104-457: Barnard " Barney " Gumble is a recurring character in the American animated TV series The Simpsons . He is voiced by Dan Castellaneta and first appeared in the series premiere episode " Simpsons Roasting on an Open Fire ". Barney is the town drunk of Springfield and one of Homer Simpson 's friends. His loud belches and desperation for alcohol serve as frequent sources of humor on

208-616: A Grammy Award for Outstanding Soul, Spoken Word, or Barbershop Album of the Year. Soon, creative disputes arose, and Barney left the group in all but name when he began dating a Japanese conceptual artist . The group realized that they were no longer popular and split up. Barney was rescued from a tar pit by Bart's pet elephant Stampy in " Bart Gets an Elephant " and he also started a snowplowing business rivaling Homer's in "Mr. Plow". Barney's commercial defamed Homer, causing Homer to lose his customers. As revenge, Homer fooled Barney into plowing

312-577: A Primetime Emmy Award for Outstanding Voice-Over Performance for voicing several characters, including Barney, in the episode " Today I Am a Clown ". "Days of Wine and D'oh'ses" was nominated for a PRISM Award in 2001. Playmates Toys created three Barney Gumble action figures as part of the World of Springfield toy line. The first one, released in August 2000, depicts Barney in his usual appearance. The second, Barney in his Plow King jacket from "Mr. Plow",

416-408: A business owner any longer, and it was explained seasons later in " And Maggie Makes Three " that his Uncle Al owns the alley and named it after him. Barney Gumble is voiced by Dan Castellaneta . Early on in the show, Castellaneta discovered that it was not easy for him to do Barney's trademark belch every time a script called for it, so he identified his best belch and told the producers to make that

520-615: A cast member singing the melody and the Dapper Dans providing backup. Castellaneta thought of the idea of Barney sobering up early in the series. He wrote a script together with his wife Deb Lacusta . They offered their script to showrunner Al Jean . Jean liked the story, but felt that it was too similar to a script the writers were already working on, " Duffless ", so he turned it down. Castellaneta and Lacusta waited several years and offered their script, which they updated, to then-show runner Mike Scully , who liked it and had them make

624-518: A child-friendly show, shifted its target group to ages 12 and up, resulting in a darker and more mature storyline. Animated film theatrical series include all early animated series: Animated Weekly (1913), The Newlyweds (1913 — 1915), Travelaughs (1913, 1915 — 1918, 1921 — 1923), Doc Yak (1913 — 1915), Colonel Heeza Liar (1913 — 1917, 1922 — 1924), Kapten Grogg  [ sv ] (1916 — 1922), Les Aventures des Pieds Nickelés (1917 — 1918),

728-664: A collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche . Though they appear to share similarities, avalanches are distinct from slush flows , mudslides , rock slides , and serac collapses. They are also different from large scale movements of ice . Avalanches can happen in any mountain range that has an enduring snowpack. They are most frequent in winter or spring, but may occur at any time of

832-424: A critical temperature gradient. Large, angular snow crystals are indicators of weak snow, because such crystals have fewer bonds per unit volume than small, rounded crystals that pack tightly together. Consolidated snow is less likely to slough than loose powdery layers or wet isothermal snow; however, consolidated snow is a necessary condition for the occurrence of slab avalanches , and persistent instabilities within

936-559: A drag force that was proportional to the square of the speed of its flow: He and others subsequently derived other formulae that take other factors into account, with the Voellmy-Salm-Gubler and the Perla-Cheng-McClung models becoming most widely used as simple tools to model flowing (as opposed to powder snow) avalanches. Since the 1990s many more sophisticated models have been developed. In Europe much of

1040-399: A driveway on Widow's Peak, a treacherous mountain just outside Springfield. When Homer saw a news report showing that Barney had become trapped in an avalanche , Homer immediately drove to the mountain and rescued Barney. The friends resolved their differences and agreed to work together. However, a heat wave hit Springfield at that exact moment, driving them both out of business. However, in

The episode was directed by Neil Affleck , who said that he had "a vested interest in getting Barney sober." However, some of the writing staff was opposed to the episode as they felt Barney sober would not be funny. Castellaneta commented, "He's still a goofy man-child...he's still got 15 years of booze left in his veins." After

1248-463: A fracture at the bottom called the stauchwall. The crown and flank fractures are vertical walls in the snow delineating the snow that was entrained in the avalanche from the snow that remained on the slope. Slabs can vary in thickness from a few centimetres to three metres. Slab avalanches account for around 90% of avalanche-related fatalities. The largest avalanches form turbulent suspension currents known as powder snow avalanches or mixed avalanches,

1352-473: A journalism career. In " Homer's Barbershop Quartet ", Barney formed a barbershop quartet with Homer, Apu Nahasapeemapetilon , and Seymour Skinner called the Be Sharps. Barney was asked to join when the other members heard him singing in a beautiful tenor voice in the restroom of Moe's Tavern , replacing the group's original fourth member, Chief Wiggum , who had been kicked out. In 1986, the Be Sharps won

1456-450: A kind of gravity current . These consist of a powder cloud, which overlies a dense avalanche. They can form from any type of snow or initiation mechanism, but usually occur with fresh dry powder. They can exceed speeds of 300 km/h (190 mph), and masses of 1,000,000 tons; their flows can travel long distances along flat valley bottoms and even uphill for short distances. In contrast to powder snow avalanches, wet snow avalanches are

1560-598: A local station of a television network broadcasts an animated series as a part of its own programming, the time-slot will vary by region. All early animated television series, the first being Crusader Rabbit (1950 — 1959), are comic cartoon series. However, later series include sports ( Speed Racer , Captain Tsubasa , Slam Dunk ), action ( Hajime no Ippo , G.I. Joe ), science fiction ( Mobile Suit Gundam , Tenchi Muyo ), drama ( Neon Genesis Evangelion ), adventure ( Dragon Ball ), martial arts ( Baki

1664-399: A long discussion about how the episode should end, the writers decided that they did not want Barney to return to being drunk at the end of the episode. Barney stayed sober for several seasons. The animators modified the appearance of the character, straightening his hair, among other things, to indicate his sobriety. Castellaneta altered his voice for the character by no longer slurring. Barney

1768-607: A long term, lasting from days to years. Experts interpret the recorded data and are able to recognize upcoming ruptures in order to initiate appropriate measures. Such systems (e.g. the monitoring of the Weissmies glacier in Switzerland ) can recognize events several days in advance. Modern radar technology enables the monitoring of large areas and the localization of avalanches at any weather condition, by day and by night. Complex alarm systems are able to detect avalanches within

1872-411: A low velocity suspension of snow and water, with the flow confined to the track surface (McClung, 1999, p. 108). The low speed of travel is due to the friction between the sliding surface of the track and the water saturated flow. Despite the low speed of travel (≈10–40 km/h), wet snow avalanches are capable of generating powerful destructive forces, due to the large mass and density. The body of

1976-400: A number of methods including hand-tossed charges, helicopter-dropped bombs, Gazex concussion lines, and ballistic projectiles launched by air cannons and artillery. Passive preventive systems such as snow fences and light walls can be used to direct the placement of snow. Snow builds up around the fence, especially the side that faces the prevailing winds . Downwind of the fence, snow build-up

2080-413: A persistent weakness in the snowpack. When a slab lying on top of a persistent weakness is loaded by a force greater than the strength of the slab and persistent weak layer, the persistent weak layer can fail and generate an avalanche. Any wind stronger than a light breeze can contribute to a rapid accumulation of snow on sheltered slopes downwind. Wind slabs form quickly and, if present, weaker snow below

2184-543: A pile of leaves (but still holding his beloved bottle of Duff Beer ) and being awoken by Bart Simpson skateboarding over his stomach, causing him to let out his trademark belch. Barney's father, Arnie Gumble, was a World War II veteran who died in 1979 in a parade float accident. Little is known about his mother, except that she lives in Norway and that she served in the United States Navy , including duty on

2288-400: A point significantly above the freezing point of water, may cause avalanche formation at any time of year. Persistent cold temperatures can either prevent new snow from stabilizing or destabilize the existing snowpack. Cold air temperatures on the snow surface produce a temperature gradient in the snow, because the ground temperature at the base of the snowpack is usually around 0 °C, and

2392-412: A point with only a small amount of snow moving initially; this is typical of wet snow avalanches or avalanches in dry unconsolidated snow. However, if the snow has sintered into a stiff slab overlying a weak layer, then fractures can propagate very rapidly, so that a large volume of snow, possibly thousands of cubic metres, can start moving almost simultaneously. A snowpack will fail when the load exceeds

2496-460: A set time period in "segments", including several such shorts. When advertising is taken into account, the cartoon itself may be only 15 — 20 minutes of the half hour, although Netflix and many other streaming companies do not show commercials. There are also series with a very short episodes lasting approximately five minutes; they have recently become more common in Japanese animation . If

2600-592: A short time in order to close (e.g. roads and rails) or evacuate (e.g. construction sites) endangered areas. An example of such a system is installed on the only access road of Zermatt in Switzerland. Two radars monitor the slope of a mountain above the road. The system automatically closes the road by activating several barriers and traffic lights within seconds such that no people are harmed. Avalanche accidents are broadly differentiated into 2 categories: accidents in recreational settings, and accidents in residential, industrial, and transportation settings. This distinction

2704-425: A source of comedy. So, of course, we went right for it." The writers also patterned the character after Norm Peterson ( George Wendt ), a character from the sitcom Cheers . In some early first season episodes, Barney had yellow hair. Later in the production of that season, the producers had it changed to brown, because they thought that his hair looked like his skin; in addition, during an artistic convention of

2808-417: A start zone where the avalanche originates, a track along which the avalanche flows, and a runout zone where the avalanche comes to rest. The debris deposit is the accumulated mass of the avalanched snow once it has come to rest in the run-out zone. For the image at left, many small avalanches form in this avalanche path every year, but most of these avalanches do not run the full vertical or horizontal length of

2912-415: A storm. Daytime exposure to sunlight will rapidly destabilize the upper layers of the snowpack if the sunlight is strong enough to melt the snow, thereby reducing its hardness. During clear nights, the snowpack can re-freeze when ambient air temperatures fall below freezing, through the process of long-wave radiative cooling, or both. Radiative heat loss occurs when the night air is significantly cooler than

3016-463: A street corner). He ultimately abandoned the car in New York City and returned to Springfield after a two-month absence. A gag in " Selma's Choice " suggests that Barney is the father of many local babies born through (presumably, paid) donation of semen and the resulting artificial insemination . Barney made a documentary film about his life as an alcoholic , titled Pukahontas . It won

3120-471: A submarine. She is seen in the season nine episode " Simpson Tide ". In " Treehouse of Horror XVII ", Barney stated that he was Polish , after mistakenly saying he was Irish in a drunken stupor. Barney was born on April 20 (which Homer remembers is also Hitler 's birthday in " Viva Ned Flanders ") In " A Star Is Burns ", Barney states that he is 40 years old. Several episodes, starting with The Way We Was , depict him as Homer's best friend in high school . In

3224-412: A sufficient quantity of airborne snow, this portion of the avalanche can become separated from the bulk of the avalanche and travel a greater distance as a powder snow avalanche. Scientific studies using radar , following the 1999 Galtür avalanche disaster , confirmed the hypothesis that a saltation layer forms between the surface and the airborne components of an avalanche, which can also separate from

3328-653: A suspended sentence. The small Austrian village of Galtür was hit by the Galtür avalanche in 1999. The village was thought to be in a safe zone but the avalanche was exceptionally large and flowed into the village. Thirty-one people died. On 1 December 2000, the Glory Bowl Avalanche formed on Mt. Glory which is located within the Teton Mountain Range in Wyoming, United States. Joel Roof

A mountain climbing camp on Lenin Peak, in what is now Kyrgyzstan, was wiped out in 1990 when an earthquake triggered a large avalanche that overran the camp. Forty-three climbers were killed. In 1993, the Bayburt Üzengili avalanche killed 60 individuals in Üzengili in

3536-413: A variety of factors such as the snow's shear strength (which is itself dependent upon crystal form) and the configuration of layers and inter-layer interfaces. The snowpack on slopes with sunny exposures is strongly influenced by sunshine . Diurnal cycles of thawing and refreezing can stabilize the snowpack by promoting settlement. Strong freeze-thaw cycles result in the formation of surface crusts during

3640-503: Is a rapid flow of snow down a slope , such as a hill or mountain. Avalanches can be triggered spontaneously, by factors such as increased precipitation or snowpack weakening, or by external means such as humans, other animals, and earthquakes . Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by

3744-403: Is a rigid fence-like structure ( snow fence ) and may be constructed of steel , wood or pre-stressed concrete . They usually have gaps between the beams and are built perpendicular to the slope, with reinforcing beams on the downhill side. Rigid barriers are often considered unsightly, especially when many rows must be built. They are also expensive and vulnerable to damage from falling rocks in

3848-579: Is called the Starting Point and typically occurs on a 30–45 degree slope. The body of the pathway is called the Track of the avalanche and usually occurs on a 20–30 degree slope. When the avalanche loses its momentum and eventually stops it reaches the Runout Zone. This usually occurs when the slope has reached a steepness that is less than 20 degrees. These degrees are not consistently true due to

3952-424: Is critically sensitive to small variations within the narrow range of meteorological conditions that allow for the accumulation of snow into a snowpack. Among the critical factors controlling snowpack evolution are: heating by the sun, radiational cooling , vertical temperature gradients in standing snow, snowfall amounts, and snow types. Generally, mild winter weather will promote the settlement and stabilization of

4056-408: Is flat enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. The snowpack is composed of ground-parallel layers that accumulate over the winter. Each layer contains ice grains that are representative of the distinct meteorological conditions during which the snow formed and was deposited. Once deposited, a snow layer continues to evolve under

4160-470: Is lessened. This is caused by the loss of snow at the fence that would have been deposited and the pickup of the snow that is already there by the wind, which was depleted of snow at the fence. When there is a sufficient density of trees , they can greatly reduce the strength of avalanches. They hold snow in place and when there is an avalanche, the impact of the snow against the trees slows it down. Trees can either be planted or they can be conserved, such as in

4264-504: Is motivated by the observed difference in the causes of avalanche accidents in the two settings. In the recreational setting most accidents are caused by the people involved in the avalanche. In a 1996 study, Jamieson et al. (pages 7–20) found that 83% of all avalanches in the recreational setting were caused by those who were involved in the accident . In contrast, all the accidents in the residential, industrial, and transportation settings were due to spontaneous natural avalanches. Because of

During World War I , an estimated 40,000 to 80,000 soldiers died as a result of avalanches during the mountain campaign in the Alps at the Austrian-Italian front, many of which were caused by artillery fire. Some 10,000 men, from both sides, died in avalanches in December 1916. In the northern hemisphere winter of 1950–1951 approximately 649 avalanches were recorded in

4680-502: The angle of repose , depends on a variety of factors, such as crystal form and moisture content. Some forms of drier and colder snow will only stick to shallower slopes, while wet and warm snow can bond to very steep surfaces. In coastal mountains, such as the Cordillera del Paine region of Patagonia , deep snowpacks collect on vertical and even overhanging rock faces. The slope angle that can allow moving snow to accelerate depends on

Deep debris deposits from avalanches will collect in catchments at the terminus of a run out, such as gullies and river beds. Slopes flatter than 25 degrees or steeper than 60 degrees typically have a lower incidence of avalanches. Human-triggered avalanches have

They are typically very difficult to predict and almost impossible to mitigate. As an avalanche moves down a slope it follows a certain pathway that is dependent on the slope's degree of steepness and the volume of snow/ice involved in the mass movement . The origin of an avalanche

Preventative measures are employed in areas where avalanches pose a significant threat to people, such as ski resorts , mountain towns, roads, and railways. There are several ways to prevent avalanches and lessen their power and develop preventative measures to reduce the likelihood and size of avalanches by disrupting the structure of

5408-473: The United States. In 2001 it was reported that globally an average of 150 people die each year from avalanches. Three of the deadliest recorded avalanches have killed over a thousand people each. Doug Fesler and Jill Fredston developed a conceptual model of the three primary elements of avalanches: terrain, weather, and snowpack. Terrain describes the places where avalanches occur, weather describes

5512-408: The ambient air temperature can be much colder. When a temperature gradient greater than 10 °C change per vertical meter of snow is sustained for more than a day, angular crystals called depth hoar or facets begin forming in the snowpack because of rapid moisture transport along the temperature gradient. These angular crystals, which bond poorly to one another and the surrounding snow, often become

Finally, along transportation corridors, large shelters, called snow sheds , can be built directly in the slide path of an avalanche to protect traffic from avalanches. Warning systems can detect avalanches which develop slowly, such as ice avalanches caused by icefalls from glaciers. Interferometric radars, high-resolution cameras, or motion sensors can monitor instable areas over

In turn, socio-environmental changes can influence the occurrence of damaging avalanches: some studies linking changes in land-use/land-cover patterns and the evolution of snow avalanche damage in mid latitude mountains show the importance of the role played by vegetation cover, that is at the root of the increase of damage when

5824-432: The bulk of the avalanche. Driving an avalanche is the component of the avalanche's weight parallel to the slope; as the avalanche progresses any unstable snow in its path will tend to become incorporated, so increasing the overall weight. This force will increase as the steepness of the slope increases, and diminish as the slope flattens. Resisting this are a number of components that are thought to interact with each other:

5928-409: The depths, crystal forms, and layering of the seasonal snowpack. Slab avalanches are formed frequently in snow that has been deposited, or redeposited by wind. They have the characteristic appearance of a block (slab) of snow cut out from its surroundings by fractures. Elements of slab avalanches include a crown fracture at the top of the start zone, flank fractures on the sides of the start zones, and

6552-532: The fact that each avalanche is unique depending on the stability of the snowpack that it was derived from as well as the environmental or human influences that triggered the mass movement. People caught in avalanches can die from suffocation , trauma, or hypothermia . From "1950–1951 to 2020–2021" there were 1,169 people who died in avalanches in the United States. For the 11-year period ending April 2006, 445 people died in avalanches throughout North America. On average, 28 people die in avalanches every winter in

6656-452: The flow of a wet snow avalanche can plough through soft snow, and can scour boulders, earth, trees, and other vegetation; leaving exposed and often scored ground in the avalanche track. Wet snow avalanches can be initiated from either loose snow releases, or slab releases, and only occur in snowpacks that are water saturated and isothermally equilibrated to the melting point of water. The isothermal characteristic of wet snow avalanches has led to

6760-460: The friction between the avalanche and the surface beneath; friction between the air and snow within the fluid; fluid-dynamic drag at the leading edge of the avalanche; shear resistance between the avalanche and the air through which it is passing, and shear resistance between the fragments within the avalanche itself. An avalanche will continue to accelerate until the resistance exceeds the forward force. Attempts to model avalanche behaviour date from

6864-470: The greatest incidence when the snow's angle of repose is between 35 and 45 degrees; the critical angle, the angle at which human-triggered avalanches are most frequent, is 38 degrees. When the incidence of human triggered avalanches is normalized by the rates of recreational use, however, hazard increases uniformly with slope angle, and no significant difference in hazard for a given exposure direction can be found. The rule of thumb is: A slope that

6968-866: The ground surface beneath the snowpack influences the stability of the snowpack, either being a source of strength or weakness. Avalanches are unlikely to form in very thick forests, but boulders and sparsely distributed vegetation can create weak areas deep within the snowpack through the formation of strong temperature gradients. Full-depth avalanches (avalanches that sweep a slope virtually clean of snow cover) are more common on slopes with smooth ground, such as grass or rock slabs. Generally speaking, avalanches follow drainages down-slope, frequently sharing drainage features with summertime watersheds. At and below tree line , avalanche paths through drainages are well defined by vegetation boundaries called trim lines , which occur where avalanches have removed trees and prevented regrowth of large vegetation. Engineered drainages, such as

7072-508: The influence of the meteorological conditions that prevail after deposition. For an avalanche to occur, it is necessary that a snowpack have a weak layer (or instability) below a slab of cohesive snow. In practice the formal mechanical and structural factors related to snowpack instability are not directly observable outside of laboratories, thus the more easily observed properties of the snow layers (e.g. penetration resistance, grain size, grain type, temperature) are used as index measurements of

7176-413: The likelihood of an avalanche. Observation and experience has shown that newly fallen snow requires time to bond with the snow layers beneath it, especially if the new snow falls during very cold and dry conditions. If ambient air temperatures are cold enough, shallow snow above or around boulders, plants, and other discontinuities in the slope, weakens from rapid crystal growth that occurs in the presence of

7280-450: The local humidity, water vapour flux, temperature and heat flux. The top of the snowpack is also extensively influenced by incoming radiation and the local air flow. One of the aims of avalanche research is to develop and validate computer models that can describe the evolution of the seasonal snowpack over time. A complicating factor is the complex interaction of terrain and weather, which causes significant spatial and temporal variability of

7384-526: The mechanical properties of the snow (e.g. tensile strength , friction coefficients, shear strength , and ductile strength ). This results in two principal sources of uncertainty in determining snowpack stability based on snow structure: First, both the factors influencing snow stability and the specific characteristics of the snowpack vary widely within small areas and time scales, resulting in significant difficulty extrapolating point observations of snow layers across different scales of space and time. Second,

7488-421: The meteorological conditions that create the snowpack, and snowpack describes the structural characteristics of snow that make avalanche formation possible. Avalanche formation requires a slope shallow enough for snow to accumulate but steep enough for the snow to accelerate once set in motion by the combination of mechanical failure (of the snowpack) and gravity. The angle of the slope that can hold snow, called

7592-414: The new snow has insufficient time to bond to underlying snow layers. Rain has a similar effect. In the short term, rain causes instability because, like a heavy snowfall, it imposes an additional load on the snowpack and once rainwater seeps down through the snow, acts as a lubricant, reducing the natural friction between snow layers that holds the snowpack together. Most avalanches happen during or soon after

7696-479: The next-door neighbor instead. "Barney was taking the standard sitcom sidekick and just making him as pathetic as possible," said Matt Groening , the creator of The Simpsons . The writers drew further inspiration from Crazy Guggenheim, a character played by comedian Frank Fontaine on The Jackie Gleason Show . Part of the reason the writers went in that direction, according to Groening, was because of "a sort of unspoken rule about not having drinking on television as

7800-427: The night and of unstable surface snow during the day. Slopes in the lee of a ridge or of another wind obstacle accumulate more snow and are more likely to include pockets of deep snow, wind slabs , and cornices , all of which, when disturbed, may result in avalanche formation. Conversely, the snowpack on a windward slope is often much shallower than on a lee slope. Avalanches and avalanche paths share common elements:

7904-407: The path. The frequency with which avalanches form in a given area is known as the return period . The start zone of an avalanche must be steep enough to allow snow to accelerate once set in motion, additionally convex slopes are less stable than concave slopes because of the disparity between the tensile strength of snow layers and their compressive strength . The composition and structure of

8008-553: The pre-show, Barney appears in a suit of the character Scratchy to entertain the people waiting in line, but he staggers around drunk and drinks in public, which led to Krusty firing him for drinking on the job. Barney later reappears during the ride portion where he appears outside Moe's Tavern, letting out his signature belch as the Simpson family chases an enlarged Maggie through Springfield. Animated series Animated television series are presented daily or on certain days of

8112-414: The prevention of development in these areas. To mitigate the effect of avalanches the construction of artificial barriers can be very effective in reducing avalanche damage. There are several types: One kind of barrier ( snow net ) uses a net strung between poles that are anchored by guy wires in addition to their foundations. These barriers are similar to those used for rockslides . Another type of barrier

8216-550: The protective forest is deforested (because of demographic growth, intensive grazing and industrial or legal causes), and at the root of the decrease of damage because of the transformation of a traditional land-management system based on overexploitation into a system based on land marginalization and reforestation, something that has happened mainly since the mid-20th century in mountain environments of developed countries. In many areas, regular avalanche tracks can be identified and precautions can be taken to minimize damage, such as

8320-460: The province of Bayburt , Turkey . A large avalanche in Montroc, France , in 1999, 300,000 cubic metres of snow slid on a 30° slope, achieving a speed in the region of 100 km/h (62 mph). It killed 12 people in their chalets under 100,000 tons of snow, 5 meters (16 feet) deep. The mayor of Chamonix was convicted of second-degree murder for not evacuating the area, but received

8424-804: The recent work was carried out as part of the SATSIE (Avalanche Studies and Model Validation in Europe) research project supported by the European Commission which produced the leading-edge MN2L model, now in use with the Service Restauration des Terrains en Montagne (Mountain Rescue Service) in France, and D2FRAM (Dynamical Two-Flow-Regime Avalanche Model), which was still undergoing validation as of 2007. Other known models are

8528-409: The relationship between readily observable snowpack characteristics and the snowpack's critical mechanical properties has not been completely developed. While the deterministic relationship between snowpack characteristics and snowpack stability is still a matter of ongoing scientific study, there is a growing empirical understanding of the snow composition and deposition characteristics that influence

8632-458: The secondary term of isothermal slides found in the literature (for example in Daffern, 1999, p. 93). At temperate latitudes wet snow avalanches are frequently associated with climatic avalanche cycles at the end of the winter season, when there is significant daytime warming. An ice avalanche occurs when a large piece of ice, such as from a serac or calving glacier, falls onto ice (such as

8736-555: The show, Groening stated that he wanted only the Simpsons to have yellow hair. Animation director Rich Moore modeled Barney's apartment on one he and several other animators who worked on the show shared, particularly the Farrah Fawcett poster and the cable spool table. The writers originally intended for the character to be the owner of Barney's Bowl-A-Rama . However, after making him "pathetic", they could not regard him as

8840-559: The show, though Barney sobered up in the Season 11 episode " Days of Wine and D'oh'ses " before relapsing three years later. Barney was inspired by the cartoon character Barney Rubble from The Flintstones and by several barflies from other television programs. In 2004, Castellaneta won an Emmy Award for voicing various characters, including Barney. Barney can be seen in The Simpsons opening credits since 2009, passed out under

8944-416: The slab may not have time to adjust to the new load. Even on a clear day, wind can quickly load a slope with snow by blowing snow from one place to another. Top-loading occurs when wind deposits snow from the top of a slope; cross-loading occurs when wind deposits snow parallel to the slope. When a wind blows over the top of a mountain, the leeward, or downwind, side of the mountain experiences top-loading, from

9048-429: The snowpack can hide below well-consolidated surface layers. Uncertainty associated with the empirical understanding of the factors influencing snow stability leads most professional avalanche workers to recommend conservative use of avalanche terrain relative to current snowpack instability. Avalanches only occur in a standing snowpack. Typically winter seasons at high latitudes, high altitudes, or both have weather that

9152-423: The snowpack, and the heat stored in the snow is re-radiated into the atmosphere. When a slab avalanche forms, the slab disintegrates into increasingly smaller fragments as the snow travels downhill. If the fragments become small enough the outer layer of the avalanche, called a saltation layer, takes on the characteristics of a fluid . When sufficiently fine particles are present they can become airborne and, given

9256-460: The snowpack, such as melting due to solar radiation, is the second-largest cause of natural avalanches. Other natural causes include rain, earthquakes, rockfall, and icefall. Artificial triggers of avalanches include skiers, snowmobiles, and controlled explosive work. Contrary to popular belief, avalanches are not triggered by loud sound; the pressure from sound is orders of magnitude too small to trigger an avalanche. Avalanche initiation can start at

9360-479: The snowpack, while passive measures reinforce and stabilize the snowpack in situ . The simplest active measure is repeatedly traveling on a snowpack as snow accumulates; this can be by means of boot-packing, ski-cutting, or machine grooming . Explosives are used extensively to prevent avalanches, by triggering smaller avalanches that break down instabilities in the snowpack, and removing overburden that can result in larger avalanches. Explosive charges are delivered by

9464-402: The snowpack; conversely, very cold, windy, or hot weather will weaken the snowpack. At temperatures close to the freezing point of water, or during times of moderate solar radiation, a gentle freeze-thaw cycle will take place. The melting and refreezing of water in the snow strengthens the snowpack during the freezing phase and weakens it during the thawing phase. A rapid rise in temperature, to

9568-404: The standard, the belch also appears on an episode of The Pitts . Castellaneta has voiced Barney every time he has appeared in the series, with the exception of the episode " Homer's Barbershop Quartet ", in which some of Barney's singing is provided by a member of The Dapper Dans , who recorded lines for all four members of the Be Sharps. Their recordings were intermixed with the cast's, often with

9672-401: The strength. The load is straightforward; it is the weight of the snow. However, the strength of the snowpack is much more difficult to determine and is extremely heterogeneous. It varies in detail with properties of the snow grains, size, density, morphology, temperature, water content; and the properties of the bonds between the grains. These properties may all metamorphose in time according to

9776-450: The stuff The Simpsons satirizes, all those simple sitcom narratives where everything is wrapped up in half an hour and everyone learns a lesson in the end." Britain's The Guardian said that Barney "should be hailed for making compulsive drinking a source of comedy on US TV, a hitherto impossible dream." Entertainment Weekly placed "Mr. Plow" sixth on their list of the best 25 Simpsons episodes in 2003. In 2004, Dan Castellaneta won

9880-1046: The style of All in the Family . The Alvin Show from Ross Bagdasarian Sr. and Beany and Cecil from Bob Clampett are also sitcoms. The 1980s and 1990s were a renaissance of the animated children and adult television series. Various broadcast networks and media companies began creating television channels and formats designed specifically for airing cartoon and anime series. Companies that already had these types of formats in place began to revamp their existing models during this time. Most of this animations were American-based or Japanese anime. Listed below are examples of television networks and channels that include animated programs. American British Japanese Canadian Australian Examples of animation-focused networks and channels are listed below; but some of them aired live-action programs occasionally. American South Korean Canadian Japanese During

9984-570: The top prize at the Springfield Film Festival. He was ready to quit drinking after winning the Festival, but unfortunately, the prize he received was a lifetime supply of Duff Beer. In " Deep Space Homer ", Barney trained to become an astronaut for NASA . Under their alcohol-ban, he quickly regained his balance and diction and was quite appropriately selected to fly with Buzz Aldrin . However, he reverted to his old ways when he

10088-421: The top to the bottom of that lee slope. When the wind blows across a ridge that leads up the mountain, the leeward side of the ridge is subject to cross-loading. Cross-loaded wind-slabs are usually difficult to identify visually. Snowstorms and rainstorms are important contributors to avalanche danger. Heavy snowfall will cause instability in the existing snowpack, both because of the additional weight and because

10192-449: The warmer months. In addition to industrially manufactured barriers, landscaped barriers, called avalanche dams stop or deflect avalanches with their weight and strength. These barriers are made out of concrete, rocks, or earth. They are usually placed right above the structure, road, or railway that they are trying to protect, although they can also be used to channel avalanches into other barriers. Occasionally, earth mounds are placed in

10296-430: The week during a prescribed time slot , including for example saturday-morning cartoons , prime time cartoons , late night anime , and weekday cartoons ; series broadcast only on weekends. The duration of an episode also varies. Traditionally, they are produced as complete half-hour or nearly half-hour programs; however, many are presented as animated shorts of 10 — 11 minutes, which can be combined for filling

10400-483: The year. In mountainous areas, avalanches are among the most serious natural hazards to life and property, so great efforts are made in avalanche control . There are many classification systems for the different forms of avalanches. Avalanches can be described by their size, destructive potential, initiation mechanism, composition, and dynamics . Most avalanches occur spontaneously during storms under increased load due to snowfall and/or erosion . Metamorphic changes in

10504-595: Was presented with a bottle of non-alcoholic champagne. Barney served in the United States Navy Reserve as a submariner on the USS Jebediah , alongside his mother, in " Simpson Tide ". In " Days of Wine and D'oh'ses ", after watching a video of his drunken antics at his birthday party, Barney resolves to get sober . He attends Alcoholics Anonymous meetings, cleans up his appearance, and attends helicopter-flying lessons. He remains sober by

10608-651: Was released in January 2003. The third, a Toys "R" Us retail exclusive, was released in July 2003 as part of a Be Sharps play set. The song "A Boozehound named Barney" from the episode " Simpsoncalifragilisticexpiala(Annoyed Grunt)cious " was included on the Go Simpsonic with The Simpsons album. Barney plays a role in The Simpsons Ride , launched in 2008 at Universal Studios Florida and Hollywood . During

10712-464: Was snowboarding recreationally in this backcountry, bowl-shaped run and triggered the avalanche. He was carried nearly 2,000 feet to the base of the mountain and was not successfully rescued. On 28 January 2003, the Tatra Mountains avalanche swept away nine out of a thirteen-member group heading to the summit of Rysy in the Tatra Mountains . The participants of the trip were students from

10816-584: Was still seen at Moe's Tavern, but only drinking lattes . The character's new addiction to coffee was suggested by writer-producer David Mirkin , who has friends who stopped drinking alcohol and became addicted to coffee. Filmcritic.com ranked Barney 18th on their 2008 list of "The 21 Best Movie Alcoholics of All Time". Recognizing the character for his appearance in The Simpsons Movie , Filmcritic called him "the most awesomely funny town drunk in pop culture". IGN ranked Barney fifth on their list of
