atmospheric circulation - Opis:
- Diurnal air temperature ranges (DTR) have been counted based on the monthly mean values of the daily maximal and minimal air temperature from 23 Antarctic stations. DTR shows a considerable spatial differentiation on the Antarctic. The lowest DTR values (4-6°C) occur along the western coast of the Antarctic Peninsula and on the subantarctic islands. At the remaining coast of Antarctica the mean DTR vary from 6-7°C to 10°C at the stations situated on higher geographical latitude. In the Antarctic inlands the largest DTR values occur at the highest parts of glacier plateau (8-9°C), while on the South Pole they are distinctly smaller (6°C). In the annual course of DTR the following types have been distinguished: oceanic type at the western coast of the Antarctic Peninsula with small DTR in summer (2-4°C) and twice higher in winter; oceanic-continental type at the coast of Eastern Antarctic with large DTR during the whole year; continental-oceanic type with high DTR in summer and still higher (up to 13°C) in winter occurring at Western Antarctic and in the Weddell Sea basin; continental type characteristic for the interior of the continent with the highest DTR in summer (11-12°C) and smaller in winter; polar type with small DTR in summer (to 3°C) and considerable higher in winter (7-8°C). A decrease of DTR occurred on the Antarctic in regions characterized by increasing temperature in the second half of the 20th century, especially on the western coast of the Antarctic Peninsula, on the coast of Ross Sea and on the Queen Maud Land. The decrease in the DTR values was connected with the quicker increase of daily minimal air temperatures. On the other hand, in the regions where cooling was noted the DTR values increase (inlands of Eastern Antarctic and South Pole, and the Weddell Sea basin), mainly due to the fall in daily minimal air temperatures.
