Variability of Air Temperature and Atmospheric Precipitation During a Period of Instrumental Observations in the Arctic : Springer : 9781402009525 : 1402009526 : 31 Oct 2002 : It has been known at least since the end of the century that the polar areas play a very important role in the formation of the Earth's climates. It is also known today that they are the most sensitive regions to climatic change, and are thus perfect case studies for the detection of such changes. The most serious obstacle to the study of climatic and other geographical elements of the polar areas (including the Arctic) has always been the severe climatic conditions which prevail in these regions. Because of these extreme con- tions, research into particular elements of the climatic system (including the atmosphere) began here much later than it did in lower latitudes. For instance, the whole area of the Arctic was not sufficiently covered with a network of meteorological stations until the late 1940s (and even t
