Characteristics of climatic types in Greenland

Greenland has a cold polar climate, which is deeply influenced by the cold current of the Arctic Ocean and the polar easterly wind. The cold current of East Greenland goes south along the east coast of Greenland, and the warm current of West Greenland goes north along the west coast of Greenland, which makes the temperature on the east and west banks of Greenland lower in the east and higher in the west. The inland of the island is covered with huge ice sheets and has a cold polar ice sheet climate. Due to the dry climate and low snowfall, it is difficult to form ice sheets on the northern and northeastern coasts. But the temperature is still extremely low, and most of the ground is bare rock, which is a barren polar desert climate. Influenced by the warm current of West Greenland, the temperature in the western coastal area is slightly higher, the climate is mild, there is no ice sheet, lichens and low grass grow on the ground, which is the most pleasant place in Greenland, and most of the island residents live in the southwest coastal area. 1 Monthly average temperature -47.2℃, July average temperature-12.2℃. There is a continuous layer of cold air over the cold inland of the island, and there is often a low-pressure air mass moving from west to east above the cold air, which makes the weather changeable, sometimes sunny and sometimes snowy. In winter (65438+1October), the average temperature in the south is MINUS 6℃, and the average temperature in the north is MINUS 35℃. In summer (July), the average temperature in the southwest coast is 8℃, and the average temperature in the northernmost summer is 3.6℃. The coldest central plateau and the coldest Leng Yue have an absolute minimum temperature of minus 70℃, which is the second "cold pole" on earth after Antarctica. The average annual precipitation decreased from 1900 mm in the south to about 50 mm in the north. In winter, except for the southwest coast affected by the warm current of West Greenland, most of the sea around Greenland will freeze. In summer, most of the sea surface around Greenland thaws, and icebergs and broken sea ice drift with the tide, but the sea ice in the north and northeast is still connected and will not melt.
