Oceanic and Atmospheric Research ( OAR ) is a division of the National Oceanic and Atmospheric Administration (NOAA). OAR is also referred to as NOAA Research .
111-486: NOAA Research is the research and development arm of NOAA and is the driving force behind NOAA environmental products and services aimed at protecting life and property and promoting sustainable economic growth. Research , conducted by programs within NOAA and through collaborations outside NOAA, focuses on enhancing the understanding of environmental phenomena such as tornadoes , hurricanes , climate variability, changes in
222-441: A capacity to grow , respond to stimuli , reproduce and, through natural selection , adapt to their environment in successive generations. More complex living organisms can communicate through various means. An ecosystem (also called an environment) is a natural unit consisting of all plants, animals, and micro-organisms ( biotic factors) in an area functioning together with all of the non-living physical ( abiotic ) factors of
333-641: A decreased food supply for the wildlife in an area. The atmosphere of the Earth serves as a key factor in sustaining the planetary ecosystem. The thin layer of gases that envelops the Earth is held in place by the planet's gravity. Dry air consists of 78% nitrogen , 21% oxygen , 1% argon , inert gases and carbon dioxide . The remaining gases are often referred to as trace gases. The atmosphere includes greenhouse gases such as carbon dioxide, methane, nitrous oxide and ozone. Filtered air includes trace amounts of many other chemical compounds . Air also contains
444-546: A gateway to Alaska during the Klondike Gold Rush . The city grew after World War II , partly due to the local company Boeing , which established Seattle as a center for its manufacturing of aircraft. Beginning in the 1980s, the Seattle area developed into a technology center ; Microsoft established its headquarters in the region. In 1994, Internet retailer Amazon was founded in Seattle, and Alaska Airlines
555-634: A great frenzy among the technology companies in Seattle but the bubble ended in early 2001. In 1999, the World Trade Organization held its conference in Seattle, which was met with protest activity . The protests and police reactions to them largely overshadowed the conference itself. In 2001, the city was impacted by the Mardi Gras Riots and then by the Nisqually earthquake the following day. Another boom began as

Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams and the works of mound-building termites are thought of as natural. People cannot find absolutely natural environments on Earth,naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in
777-441: A number of technology companies, including Amazon , F5 Networks , RealNetworks , Nintendo of America , and T-Mobile . This success brought an influx of new residents with a population increase within city limits of almost 50,000 between 1990 and 2000, and saw Seattle's real estate become some of the most expensive in the country. Seattle in this period attracted attention as home to the companies opened operations in or around
888-478: A number of theaters in the city exhibiting vaudeville acts and silent movies. He went on to become one of America's greatest theater and movie tycoons. Scottish-born architect B. Marcus Priteca designed several theaters for Pantages in Seattle, which were later demolished or converted to other uses. Seattle's surviving Paramount Theatre , on which he collaborated, was not a Pantages theater. War work again brought local prosperity during World War II , centered on
999-454: A pond from many other aquatic terrain features, such as stream pools and tide pools . Humans impact the water in different ways such as modifying rivers (through dams and stream channelization ), urbanization and deforestation . These impact lake levels, groundwater conditions, water pollution, thermal pollution, and marine pollution . Humans modify rivers by using direct channel manipulation. We build dams and reservoirs and manipulate
1110-431: A prominent 19th-century leader of the local Duwamish and Suquamish tribes. Seattle currently has high populations of Native Americans alongside Americans with strong Asian, African, European, and Scandinavian ancestry, and, as of 2015, hosts the fifth-largest LGBT community in the U.S. Logging was Seattle's first major industry, but by the late 19th century the city had become a commercial and shipbuilding center as
1221-400: A qualitative and quantitative understanding of the principal areas or spheres of Earth. The Earth's crust or lithosphere , is the outermost solid surface of the planet and is chemically, physically and mechanically different from underlying mantle . It has been generated greatly by igneous processes in which magma cools and solidifies to form solid rock. Beneath the lithosphere lies

#17327916325551332-430: A river is usually in a channel , made up of a stream bed between banks . In larger rivers there is often also a wider floodplain shaped by waters over-topping the channel. Flood plains may be very wide in relation to the size of the river channel. Rivers are a part of the hydrological cycle . Water within a river is generally collected from precipitation through surface runoff , groundwater recharge , springs and
1443-485: A second time at the site of present-day Pioneer Square , naming this new settlement Duwamps . Charles Terry and John Low remained at the original landing location, reestablished their old land claim and called it "New York", but renamed "New York Alki" in April 1853, from a Chinook word meaning, roughly, "by and by" or "someday". For the next few years, New York Alki and Duwamps competed for dominance, but in time Alki
1554-546: A stronger economy through marine products and businesses, such as biotechnology and sustainable aquaculture. NOAA’s Pacific Marine Environmental Laboratory (PMEL) in Seattle , Washington, designed Deep-ocean Assessment and Reporting of Tsunamis (DART-II) technology, which provides two-way communication capabilities, allowing engineers the ability to troubleshoot these systems from the lab and repair them remotely when possible. This capability minimizes system downtime, especially in
1665-604: A total area of 142.5 square miles (369 km ), 84 square miles (220 km ) of which is land and 58.1 square miles (150 km ) is water (41% of the total area). According to the Köppen climate classification system, Seattle has a warm-summer Mediterranean climate ( Csb ), while under the Trewartha system, it is labeled an oceanic climate ( Dobk ). It has cool, wet winters and mild, relatively dry summers, covering characteristics of both climate types. The climate
1776-545: A valid assessment of the impact of how climate change might affect the climate and ecology of the Great Lakes . The CHARM model provides a realistic surface-atmosphere feedback portrayal, and accounts for runoff from land surfaces. It allows researchers to predict that global warming likely will bring higher temperatures and increased precipitation to the Great Lakes. Development of a second generation of CHARM
1887-507: A variable amount of water vapor and suspensions of water droplets and ice crystals seen as clouds . Many natural substances may be present in tiny amounts in an unfiltered air sample, including dust , pollen and spores , sea spray , volcanic ash and meteoroids . Various industrial pollutants also may be present, such as chlorine (elementary or in compounds), fluorine compounds, elemental mercury , and sulphur compounds such as sulphur dioxide (SO 2 ). The ozone layer of
1998-436: Is a terrain feature , a body of water that is localized to the bottom of basin . A body of water is considered a lake when it is inland, is not part of an ocean and is larger and deeper than a pond . Natural lakes on Earth are generally found in mountainous areas, rift zones and areas with ongoing or recent glaciation . Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of
2109-409: Is an open research network consisting of seven federal research laboratories, six program offices, sixteen Cooperative Institutes (which are non-federal, non-profit research institutions in 5-10 year collaborative partnerships with NOAA), and 33 university based Sea Grant programs. OAR also relies on work performed at numerous public, private, and academic institutions. Weather Program Office includes
2220-522: Is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt. Though generally recognized as several separate oceans, these waters comprise one global, interconnected body of salt water often referred to as the World Ocean or global ocean. The deep seabeds are more than half the Earth's surface, and are among the least-modified natural environments. The major oceanic divisions are defined in part by
2331-522: Is based in SeaTac, Washington , serving Seattle–Tacoma International Airport , Seattle's international airport. The stream of new software, biotechnology , and Internet companies led to an economic revival, which increased the city's population by almost 50,000 in the decade between 1990 and 2000. The culture of Seattle is heavily defined by its significant musical history . Between 1918 and 1951, nearly 24 jazz nightclubs existed along Jackson Street, from
SECTION 20
#17327916325552442-455: Is found in various kinds of natural body of water . An ocean is a major body of saline water and a component of the hydrosphere. Approximately 71% of the surface of the Earth (an area of some 362 million square kilometers) is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas . More than half of this area is over 3,000 meters (9,800 ft) deep. Average oceanic salinity
2553-791: Is from the Old English wildeornes , which in turn derives from wildeor meaning wild beast (wild + deor = beast, deer). From this point of view, it is the wildness of a place that makes it a wilderness. The mere presence or activity of people does not disqualify an area from being "wilderness". Many ecosystems that are, or have been, inhabited or influenced by activities of people may still be considered "wild". This way of looking at wilderness includes areas within which natural processes operate without very noticeable human interference. Wildlife includes all non- domesticated plants, animals and other organisms. Domesticating wild plant and animal species for human benefit has occurred many times all over
2664-506: Is hilly in some places. Like Rome, the city is said to lie on seven hills ; the lists vary but typically include Capitol Hill , First Hill , West Seattle , Beacon Hill , Queen Anne , Magnolia, and the former Denny Hill . The Wallingford , Delridge , Mount Baker , Seward Park , Washington Park , Broadmoor , Madrona , Phinney Ridge , Sunset Hill , Blue Ridge , Broadview , Laurelhurst , Hawthorne Hills , Maple Leaf , and Crown Hill neighborhoods are all located on hills. Many of
2775-440: Is increasingly rare, wild nature (e.g., unmanaged forests , uncultivated grasslands , wildlife , wildflowers ) can be found in many locations previously inhabited by humans. Goals for the benefit of people and natural systems, commonly expressed by environmental scientists and environmentalists include: In some cultures the term environment is meaningless because there is no separation between people and what they view as
2886-743: Is situated on an isthmus between Puget Sound , an inlet of the Pacific Ocean , and Lake Washington . It is the northernmost major city in the United States, located about 100 miles (160 km) south of the Canadian border . A gateway for trade with East Asia , the Port of Seattle is the fourth-largest port in North America in terms of container handling as of 2021 . The Seattle area has been inhabited by Native Americans (such as
2997-491: Is sometimes characterized as a "modified Mediterranean" climate because it is cooler and wetter than a "true" Mediterranean climate, but shares the characteristic dry summer (which has a strong influence on the region's vegetation). Temperature extremes are moderated by the adjacent Puget Sound , greater Pacific Ocean , and Lake Washington . Thus extreme heat waves are rare in the Seattle area, as are very cold temperatures (below about 15 °F; −9 °C). The Seattle area
3108-470: Is the most populous city in both the state of Washington and the Pacific Northwest region of North America , and the 18th-most populous city in the United States. The Seattle metropolitan area 's population is 4.02 million, making it the 15th-largest in the United States. Its growth rate of 21.1% between 2010 and 2020 made it one of the country's fastest-growing large cities. Seattle
3219-671: Is the application of science and technology to predict the state of the atmosphere for a future time and a given location. The atmosphere is a chaotic system , and small changes to one part of the system can grow to have large effects on the system as a whole. Human attempts to control the weather have occurred throughout human history, and there is evidence that civilized human activity such as agriculture and industry has inadvertently modified weather patterns. Evidence suggests that life on Earth has existed for about 3.7 billion years. All known life forms share fundamental molecular mechanisms, and based on these observations, theories on
3330-568: Is the cloudiest region of the Continental United States , due in part to frequent storms and lows moving in from the adjacent Pacific Ocean. Seattle is cloudy 201 days out of the year and partly cloudy 93 days. With many more "rain days" than other major American cities, Seattle has a well-earned reputation for frequent rain: In an average year, there are 150 days in which at least 0.01 inches (0.25 mm) of precipitation falls, more days than in nearly all U.S. cities east of
3441-430: Is the one originally developed by Wladimir Köppen . The Thornthwaite system , in use since 1948, uses evapotranspiration as well as temperature and precipitation information to study animal species diversity and the potential impacts of climate changes . Weather is a set of all the phenomena occurring in a given atmospheric area at a given time . Most weather phenomena occur in the troposphere , just below

NOAA researchers closely monitor the Earth's atmosphere searching for clues about long-term changes in the global climate. The data collected worldwide by NOAA researchers contributes to the understanding of complex climatic systems and the ability to forecast changes. NOAA Research organizations conduct research on
3774-525: The 1962 World's Fair , for which the Space Needle was built. Another major local economic downturn was in the late 1960s and early 1970s, at a time when Boeing was heavily affected by the oil crises , loss of government contracts, and costs and delays associated with the Boeing 747 . Many people left the area to look for work elsewhere, and two local real estate agents put up a billboard reading "Will
3885-618: The Alaska–Yukon–Pacific Exposition of 1909, which is largely responsible for the layout of today's University of Washington campus. A shipbuilding boom in the early part of the 20th century became massive during World War I , making Seattle somewhat of a company town. The subsequent retrenchment led to the Seattle General Strike of 1919 , an early general strike in the country. A 1912 city development plan by Virgil Bogue went largely unused. Seattle
3996-569: The Duwamish , who had at least 17 villages around Elliot Bay) for at least 4,000 years before the first permanent European settlers. Arthur A. Denny and his group of travelers, subsequently known as the Denny Party , arrived from Illinois via Portland, Oregon , on the schooner Exact at Alki Point on November 13, 1851. The settlement was moved to the eastern shore of Elliott Bay in 1852 and named "Seattle" in honor of Chief Seattle ,
4107-663: The Lake Washington Ship Canal (consisting of two man-made canals, Lake Union , and the Hiram M. Chittenden Locks at Salmon Bay , ending in Shilshole Bay on Puget Sound). The sea, rivers, forests, lakes, and fields surrounding Seattle were once rich enough to support one of the world's few sedentary hunter-gatherer societies. In modern times the surrounding area lends itself well to sailing, skiing, bicycling, camping, and hiking year-round. The city
4218-790: The Pacific Ring of Fire , Seattle is in a major earthquake zone . On February 28, 2001, the magnitude 6.8 Nisqually earthquake did significant architectural damage, especially in the Pioneer Square area (built on reclaimed land , as are the Industrial District and part of the city center), and caused one fatality. Other strong earthquakes occurred on January 26, 1700 (estimated at 9 magnitude), December 14, 1872 (7.3 or 7.4), April 13, 1949 (7.1), and April 29, 1965 (6.5). The 1965 quake caused three deaths in Seattle directly and one more by heart failure. Although
4329-759: The Rocky Mountains . However, because it often has merely a light drizzle falling from the sky for many days, Seattle actually receives significantly less rainfall (or other precipitation) overall than many other major U.S. cities like New York City , Miami , or Houston . According to the 2012–2016 American Community Survey (ACS), the racial makeup of the city was 65.7% White Non-Hispanic , 16.9% Asian , 6.8% Black or African American , 6.6% Hispanic or Latino of any race, 0.4% Native American , 0.9% Pacific Islander , 0.2% other races, and 5.6% two or more races . Seattle's population historically has been predominantly white. The 2010 census showed that Seattle
4440-525: The Seattle Fault passes just south of the city center, neither it nor the Cascadia subduction zone has caused an earthquake since the city's founding. The Cascadia subduction zone poses the threat of an earthquake of magnitude 9.0 or greater, capable of seriously damaging the city and collapsing many buildings, especially in zones built on fill. According to the U.S. Census Bureau , the city has
4551-624: The United States Lake Survey . The Coast Survey was created to conduct hydrographic surveys of the coastline of the United States, while the Lake Survey was created to undertake "a hydrographic survey of northwestern lakes," i.e, the Great Lakes . Research executed by the scientists of the Lake Survey was innovative and holistic: the first current meters were developed to understand water flow rates, and forecasting techniques were greatly enhanced to predict water levels and

As schools across Washington lost funding and attendance, the university actually prospered during the time period as they focused on growing their student enrollment. While Seattle public schools were influenced by Washington's superintendent Worth McClure, they still struggled to pay teachers and maintain attendance. Seattle was the home base of impresario Alexander Pantages who, starting in 1902, opened

The origins of NOAA Research date to the creation of the Survey of the Coast (renamed the United States Coast Survey in 1836 and the United States Coast and Geodetic Survey in 1878) by President Thomas Jefferson in 1807 and to the creation in 1841 of
5550-421: The stratosphere . Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric conditions over longer periods of time. When used without qualification, "weather" is understood to be the weather of Earth. Weather occurs due to density (temperature and moisture) differences between one place and another. These differences can occur due to

#17327916325555772-518: The Earth's atmosphere plays an important role in reducing the amount of ultraviolet (UV) radiation that reaches the surface. As DNA is readily damaged by UV light, this serves to protect life at the surface. The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes. Earth's atmosphere can be divided into five main layers. These layers are mainly determined by whether temperature increases or decreases with altitude. From highest to lowest, these layers are: Within

The Wah Mee massacre in 1983 resulted in the killing of 13 people in an illegal gambling club in the Seattle Chinatown-International District . Prosperity began to return in the 1980s beginning with Microsoft 's 1979 move from Albuquerque, New Mexico , to nearby Bellevue, Washington . Seattle and its suburbs became home to
6105-485: The Seattle area for at least 4,000 years. By the time the first European settlers arrived, the Duwamish people occupied at least 17 villages in the areas around Elliott Bay . The name for the modern city of Seattle in Lushootseed , dᶻidᶻəlal̓ič , meaning "little crossing-over place", comes from one of these villages, which was located at the present-day King Street Station . In May 1792, George Vancouver
6216-415: The abiotic constituents of their biotope . A more significant number or variety of species or biological diversity of an ecosystem may contribute to greater resilience of an ecosystem because there are more species present at a location to respond to change and thus "absorb" or reduce its effects. This reduces the effect before the ecosystem's structure changes to a different state. This is not universally

In the late 20th and early 21st century, the city also was the origin of several rock bands, including Foo Fighters , Heart , and Jimi Hendrix , and the subgenre of grunge and its pioneering bands, including Alice in Chains , Nirvana , Pearl Jam , Soundgarden , and others. Archaeological excavations suggest that Native Americans have inhabited
7326-624: The direction of the rivers and water path. Dams can usefully create reservoirs and hydroelectric power. However, reservoirs and dams may negatively impact the environment and wildlife. Dams stop fish migration and the movement of organisms downstream. Urbanization affects the environment because of deforestation and changing lake levels, groundwater conditions, etc. Deforestation and urbanization go hand in hand. Deforestation may cause flooding, declining stream flow and changes in riverside vegetation. The changing vegetation occurs because when trees cannot get adequate water they start to deteriorate, leading to

During this period the road now known as Yesler Way won the nickname "Skid Road", supposedly after the timber skidding down the hill to Henry Yesler 's sawmill. The later dereliction of the area may be a possible origin for the term which later entered the wider American lexicon as Skid Row . Like much of the U.S. West , Seattle experienced conflicts between labor and management and ethnic tensions that culminated in

NOAA research is intended to: The laboratories that are part of NOAA Research are located throughout the United States near their areas of focus. These include: The NOAA Research Laboratories conduct an integrated program of research, technology development, and services to improve
8436-401: The hilliest areas are near the city center, with Capitol Hill, First Hill, and Beacon Hill collectively constituting something of a ridge along an isthmus between Elliott Bay and Lake Washington. The break in the ridge between First Hill and Beacon Hill is man-made, a result of two of the many regrading projects that reshaped the topography of the city center. The topography of the city center
8547-418: The last person leaving Seattle – Turn out the lights." Seattle remained the corporate headquarters of Boeing until 2001, when the company separated its headquarters from its major production facilities; the headquarters were moved to Chicago. The Seattle area is still home to Boeing's Renton narrow-body plant and Everett wide-body plant . The company's credit union for employees, BECU , remains based in
8658-425: The late 19th and early 20th centuries were almost entirely from Guangdong Province . The Seattle area is also home to a large Vietnamese population of more than 55,000 residents, as well as over 30,000 Somali immigrants. The Seattle-Tacoma area is also home to one of the largest Cambodian communities in the United States, numbering about 19,000 Cambodian Americans, and one of the largest Samoan communities in

Additionally, the Seattle area had the highest percentage of self-identified mixed-race people of any large metropolitan area in the United States, according to the 2000 United States Census Bureau. According to a 2012 HistoryLink study, Seattle's 98118 ZIP code (in the Columbia City neighborhood) was one of the most diverse ZIP Code Tabulation Areas in
8880-415: The mantle which is heated by the decay of radioactive elements . The mantle though solid is in a state of rheic convection . This convection process causes the lithospheric plates to move, albeit slowly. The resulting process is known as plate tectonics . Volcanoes result primarily from the melting of subducted crust material or of rising mantle at mid-ocean ridges and mantle plumes . Most water
8991-620: The miners in Alaska and the Yukon . Few of those working men found lasting wealth. However, it was Seattle's business of clothing the miners and feeding them salmon that panned out in the long run. Along with Seattle, other cities like Everett , Tacoma , Port Townsend , Bremerton , and Olympia , all in the Puget Sound region, became competitors for exchange, rather than mother lodes for extraction, of precious metals. The boom lasted into
9102-410: The natural environmental dynamics in contrast to environmental changes not within natural variances. A common solution is to adapt a static view neglecting natural variances to exist. Methodologically, this view could be defended when looking at processes which change slowly and short time series, while the problem arrives when fast processes turns essential in the object of the study. Climate looks at
9213-486: The natural world, or their surroundings. Specifically in the United States and Arabian countries many native cultures do not recognize the "environment", or see themselves as environmentalists. Seattle Seattle ( / s i ˈ æ t əl / see- AT -əl ) is a city on the West Coast of the United States . It is the seat of King County , Washington . With a 2023 population of 755,078 it
9324-409: The origin of life attempt to find a mechanism explaining the formation of a primordial single cell organism from which all life originates. There are many different hypotheses regarding the path that might have been taken from simple organic molecules via pre-cellular life to protocells and metabolism. Although there is no universal agreement on the definition of life, scientists generally accept that
9435-506: The other. The massive environmental changes of humanity in the Anthropocene have fundamentally effected all natural environments including: climate change , biodiversity loss and pollution from plastic and other chemicals in the air and water . More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in an agricultural field,
9546-438: The physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (i.e.: exchange of materials between living and nonliving parts) within the system is an ecosystem." The human ecosystem concept is then grounded in the deconstruction of the human/nature dichotomy , and the emergent premise that all species are ecologically integrated with each other, as well as with
9657-400: The planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems. Deserts, rain forests, plains, and other areas—including the most developed urban sites—all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by civilized human factors, most scientists agree that wildlife around
9768-415: The planet, its natural environment and humans' existence. It is clear the planet is warming, and warming rapidly. This is due to the greenhouse effect , which is caused by greenhouse gases, which trap heat inside the Earth's atmosphere because of their more complex molecular structure which allows them to vibrate and in turn trap heat and release it back towards the Earth. This warming is also responsible for
9879-411: The population, Spanish was spoken by 4.5% of the population, speakers of other Indo-European languages made up 3.9%, and speakers of other languages made up 2.5%. Seattle's foreign-born population grew 40% between the 1990 and 2000 censuses. The Chinese population in the Seattle area has origins in mainland China , Hong Kong, Southeast Asia, and Taiwan . The earliest Chinese-Americans that came in
9990-586: The production of Boeing aircraft. The war dispersed the city's numerous Japanese-American businessmen due to the Japanese American internment . After the World War II, however, the local economy dipped. It rose again with Boeing's growing dominance in the commercial airliner market. Seattle celebrated its restored prosperity and made a bid for world recognition with the Century 21 Exposition ,
10101-690: The quality, relevance, and performance of research conducted at the OAR laboratories. These reviews help to strategically position laboratories in their planning of future science and are intended to ensure that OAR laboratory research is linked to the NOAA Next Generation Strategic Plan, remains relevant to the NOAA research mission and its priorities, and is consistent with NOAA planning, programming, and budgeting processes. NOAA Research partners with research-oriented universities and institutions to share data and resources to advance
10212-479: The relationship to lakefront property. The science and technology that NOAA Research produces is not only relevant to society, it anticipates and responds to partners’ needs to demonstrates the value of technologies so that partners can deploy them into their applications. OAR works with end-users to integrate mature technologies (and associated expertise) into larger systems, either in NOAA operations or partner applications, via testbeds, patents, etc. NOAA Research

Their current is confined within a bed and stream banks . Streams play an important corridor role in connecting fragmented habitats and thus in conserving biodiversity . The study of streams and waterways in general is known as surface hydrology . A lake (from Latin lacus )
10434-495: The statistics of temperature , humidity , atmospheric pressure , wind , rainfall , atmospheric particle count and other meteorological elements in a given region over long periods of time. Weather , on the other hand, is the present condition of these same elements over periods up to two weeks. Climates can be classified according to the average and typical ranges of different variables, most commonly temperature and precipitation. The most commonly used classification scheme
10545-434: The sun angle at any particular spot, which varies by latitude from the tropics. The strong temperature contrast between polar and tropical air gives rise to the jet stream . Weather systems in the mid-latitudes , such as extratropical cyclones , are caused by instabilities of the jet stream flow. Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of
10656-775: The surface of the earth today exist free from human contact, although some genuine wilderness areas continue to exist without any forms of human intervention. Global biogeochemical cycles are critical to life, most notably those of water , oxygen , carbon , nitrogen and phosphorus . Wilderness is generally defined as a natural environment on Earth that has not been significantly modified by human activity. The WILD Foundation goes into more detail, defining wilderness as: "The most intact, undisturbed wild natural areas left on our planet – those last truly wild places that humans do not control and have not developed with roads, pipelines or other industrial infrastructure." Wilderness areas and protected parks are considered important for
10767-420: The survival of certain species , ecological studies, conservation , solitude, and recreation . Wilderness is deeply valued for cultural, spiritual, moral , and aesthetic reasons. Some nature writers believe wilderness areas are vital for the human spirit and creativity. The word, "wilderness", derives from the notion of wildness ; in other words that which is not controllable by humans. The word etymology
10878-538: The understanding of Earth's atmosphere, oceans and inland waters, and to describe and predict changes occurring to them. The laboratories and their field stations are located across the country and around the world. The laboratories have established formal collaborative agreements with universities/non-profit research institutions to form joint research institutes pertaining to the Earth's oceans, inland waters, intermountain west, atmosphere, and arctic environment. Scientific reviews are conducted every five years to evaluate
10989-758: The upper and lower atmosphere as well as the space environment. Their findings form the basis for NOAA's contributions to major national and international environmental programs and agreements. For instance, improvements in forecast and warning services provided by the National Weather Service are a direct result of NOAA research. Improvements in numerical modeling, observations gathered by satellites and Doppler weather radars (NEXRAD), and sophisticated weather warning and information processing and communications systems, have collectively led to significantly improved severe weather forecasts and warnings. Other research programs focus on observation and study of
11100-531: The way to their claim passed three scouts of the Denny Party. Members of the Denny Party claimed land on Alki Point on September 28, 1851. The rest of the Denny Party set sail on the schooner Exact from Portland , Oregon, stopping in Astoria , and landed at Alki Point during a rainstorm on November 13, 1851. After a difficult winter, most of the Denny Party relocated across Elliott Bay and claimed land
11211-411: The world is (now) impacted by human activities. It is the common understanding of natural environment that underlies environmentalism — a broad political , social and philosophical movement that advocates various actions and policies in the interest of protecting what nature remains in the natural environment, or restoring or expanding the role of nature in this environment. While true wilderness
11322-826: The world, there are many lakes because of chaotic drainage patterns left over from the last ice age . All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them. A pond is a body of standing water , either natural or human-made, that is usually smaller than a lake . A wide variety of human-made bodies of water are classified as ponds, including water gardens designed for aesthetic ornamentation, fish ponds designed for commercial fish breeding and solar ponds designed to store thermal energy. Ponds and lakes are distinguished from streams by their current speed . While currents in streams are easily observed, ponds and lakes possess thermally driven micro-currents and moderate wind-driven currents. These features distinguish
11433-465: The year. On the Earth's surface, temperatures usually range ±40 °C (100 °F to −40 °F) annually. Over thousands of years, changes in the Earth's orbit have affected the amount and distribution of solar energy received by the Earth and influenced long-term climate. Surface temperature differences in turn cause pressure differences. Higher altitudes are cooler than lower altitudes due to differences in compressional heating. Weather forecasting
11544-484: Was abandoned and its residents moved across the bay to join the rest of the settlers. David Swinson "Doc" Maynard , one of the founders of Duwamps, was the primary advocate to name the settlement Seattle after Chief Seattle ( Lushootseed : siʔaɫ , anglicized as "Seattle"), chief of the Duwamish and Suquamish tribes. The name "Seattle" appears on official Washington Territory papers dated May 23, 1853, when
11655-754: Was also changed by the construction of a seawall and the artificial Harbor Island (completed 1909) at the mouth of the city's industrial Duwamish Waterway , the terminus of the Green River . The highest point within city limits is at High Point in West Seattle, which is located near 35th Ave SW and SW Myrtle St. North of the city center, the Lake Washington Ship Canal connects Puget Sound to Lake Washington. It incorporates four natural bodies of water: Lake Union , Salmon Bay , Portage Bay , and Union Bay . Due to its location in
11766-478: Was founded in the immediate wake of the fire. The Panic of 1893 hit Seattle hard. The second and most dramatic boom resulted from the Klondike Gold Rush , which ended the depression that had begun with the Panic of 1893 . In a short time, Seattle became a major transportation center. On July 14, 1897, the S.S. Portland docked with its famed "ton of gold", and Seattle became the main transport and supply point for
11877-730: Was mildly prosperous in the 1920s but was particularly hard hit in the Great Depression, experiencing some of the country's harshest labor strife in that era. Violence during the Maritime Strike of 1934 cost Seattle much of its maritime traffic, which was rerouted to the Port of Los Angeles . The Great Depression in Seattle affected many minority groups, one being the Asian Pacific Americans; they were subject to racism, loss of property, and failed claims of unemployment due to citizenship status. Seattle
11988-497: Was one of the major cities that benefited from programs such as the Works Progress Administration , CCC , Public Works Administration , and others. The workers, mostly men, built roads, parks, dams, schools, railroads, bridges, docks, and even historical and archival record sites and buildings. Seattle faced significant unemployment, loss of lumber and construction industries as Los Angeles prevailed as
12099-448: Was one of the whitest big cities in the country, although its proportion of white residents has been gradually declining. In 1960, whites constituted 91.6% of the city's population, while in 2010 they constituted 69.5%. According to the 2006–2008 American Community Survey , approximately 78.9% of residents over the age of five spoke only English at home. Those who spoke Asian languages other than Indo-European languages made up 10.2% of
12210-687: Was re-incorporated December 2, 1869, with a mayor–council government . The corporate seal of the City of Seattle carries the date "1869" and a likeness of Chief Seattle in left profile. That same year, Seattle acquired the epithet of the "Queen City", a designation officially changed in 1982 to the "Emerald City". Seattle has a history of boom-and-bust cycles, like many other cities near areas of extensive natural and mineral resources. Seattle has risen several times economically, then gone into precipitous decline, but it has typically used those periods to rebuild solid infrastructure. The first such boom, covering
12321-641: Was the first European to visit the Seattle area during his 1791–1795 expedition for the Royal Navy , which sought to chart the Pacific Northwest for the British. In 1851, a large party of American pioneers led by Luther Collins made a location on land at the mouth of the Duwamish River ; they formally claimed it on September 14, 1851. Thirteen days later, members of the Collins Party on
