18-499: Chimbu is located in the central highlands cordillera of Papua New Guinea. It shares geographic and political boundaries with five provinces: Jiwaka , Eastern Highlands , Southern Highlands , Gulf and Madang . It is a significant source of organically produced coffee . Chimbu is a province with limited natural resources and very rugged mountainous terrain. The economic progress of the province has been slower than some other highlands provinces. There are seven secondary schools in

36-516: A councillor who sits in the Council Assembly. All the councillors are democratically elected and Presidents are elected in the Council Assembly. For census purposes, the LLG areas are again subdivided into wards and those into census units. The province was governed by a decentralised provincial administration, headed by a Premier, from 1977 to 1995. Following reforms taking effect that year,

54-487: A lower elevation, as the north-facing slopes receive less sunlight ( solar irradiance ) than south-facing slopes. The converse will occur in the Southern Hemisphere. The glacier equilibrium line is the point of transition between the accumulation zone and ablation zone . It is the line where the mass of these two zones is equal. Depending on the thickness of the glacier, this line can seem as though it

72-470: A transient snow line is called the "climatic snow line" and is used as a parameter to classify regions according to climatic conditions. The boundary between the accumulation zone and the ablation zone on glaciers is called the "annual snow line". The glacier region below this snow line was subject to melting in the previous season. The term "orographic snow line" is used to describe the snow boundary on surfaces other than glaciers. The term "regional snow line"

90-651: Is a small chain and/or network system of mountain ranges , such as those in the west coast of the Americas . The term is borrowed from Spanish , where the word comes from cordilla , a diminutive of cuerda ('rope'). The term is most commonly used in physical geography and is particularly applied to the various large mountain systems of the American Cordillera , such as the Andes of South America , and less frequently to other mountain ranges in

108-420: Is leaning more towards one zone but it is determined by the actual mass of ice in either zone. The rates of ablation and accumulation can also be used to determine the location of this line. This point is an important location to use in determining whether a glacier is growing or shrinking. A higher glacier equilibrium line will indicate that the glacier is shrinking, whereas a lower line will indicate that

126-404: Is the level above which snow will lie all year. Snow line is an umbrella term for different interpretations of the boundary between snow -covered surface and snow-free surface. The definitions of the snow line may have different temporal and spatial focus. In many regions the changing snow line reflect seasonal dynamics. The final height of the snow line in a mountain environment at the end of

144-548: Is therefore necessary to lower the temperature further against the surroundings and keep the snow from melting. Furthermore, large-scale oceanic currents such as the North Atlantic Current can have significant effects over large areas (in this case warming northern Europe, extending even to some Arctic Ocean regions). In the Northern Hemisphere the snow line on the north-facing slopes is at

162-468: Is used to describe large areas. The "permanent snow line" is the level above which snow will lie all year. The interplay of elevation and latitude affects the precise placement of the snow line at a particular location. At or near the equator , it is typically situated at approximately 4,500 metres (15,000 ft) above sea level . As one moves towards the Tropic of Cancer and Tropic of Capricorn ,

180-563: The " ridge " that rims the Pacific Ocean . In Colombia and Venezuela , cordilleras are named according to their position: Cordillera Occidental , Central , and Oriental . Various local names are used for the cordilleras in Ecuador , Peru , Bolivia , Chile and Argentina . Such mountain systems have a complex structure, which is usually the result of folding and faulting accompanied by volcanic activity . In South America,

198-526: The elevation of the snow line. Areas near a coast might have a lower snow line than areas of the same elevation and latitude situated in a landmass interior due to more winter snowfall and because the average summer temperature of the surrounding lowlands would be warmer away from the sea. (This applies even in the tropics, since areas far from the sea will have larger diurnal temperature ranges and potentially less moisture, as observed with Kilimanjaro and presently glacier-free Mount Meru .) A higher elevation

216-465: The glacier is growing. The terminus of a glacier advances or retreats based on the location of this equilibrium line. Scientists are using remote sensing to better estimate the locations of this line on glaciers around the world. Using satellite imagery , scientists are able to identify whether the glacier is growing or receding. This is a very helpful tool for analyzing glaciers that are difficult to access. Using this technology we can better gauge

234-450: The melting season is subject to climatic variability, and therefore may be different from year to year. The snow line is measured using automatic cameras, aerial photographs , or satellite images . Because the snow line can be established without on-the-ground measurements, it can be measured in remote and difficult to access areas. Therefore, the snow line has become an important variable in hydrological models . The average elevation of

252-500: The national government reassumed some powers, and the role of Premier was replaced by a position of Governor, to be held by the winner of the province-wide seat in the National Parliament of Papua New Guinea . The province and each district is represented by a Member of the National Parliament . There is one provincial electorate and each district is a local ("Open") electorate. Cordillera A cordillera

270-587: The parameter at first increases: in the Himalayas the permanent snow line can be as high as 5,700 metres (19,000 feet). Beyond the Tropics , the snow line becomes progressively lower as the latitude increases, to just below 3,000 metres (9,800 ft) in the Alps and falling all the way to sea level itself at the ice caps near the poles . In addition, the relative location to the nearest coastline can influence

288-471: The province: Kondiu Rosary, Yauwe Moses, Kerowagi, Muaina, Gumine, Mt Willem and Kundiawa Day Secondary School. The province also has many high and primary schools. The province is subdivided into six districts , with each district further subdivided into 18 rural LLGs and 2 urban LLGs areas. Each of the RLLGs are headed by a President and Urban LLG by a Mayor. Each LLGs have various council wards represented by

306-538: The ranges include numerous volcanic peaks . The Andes cordillera has Ojos del Salado , the highest active volcano in the world and second-highest point in the Western Hemisphere (though not itself a volcano, Argentina's Aconcagua , at 6,960 m or 22,830 ft, is the highest point in the Western Hemisphere). Some of the volcanoes have been active in historical times . Aside from

324-481: The volcanic peaks, the cordilleran crests include many narrow ridges, some of which reach into the zone of permanent snow . Between the ranges are numerous inhabited valleys , basins and low plateaus , with a wide range of elevations . Snow line The climatic snow line is the boundary between a snow -covered and snow-free surface. The actual snow line may adjust seasonally, and be either significantly higher in elevation, or lower. The permanent snow line
