What is the polar climate zone like?
Therefore, the remarkable feature of the polar climate is that it is cold all year round. The temperature in the hottest month in summer is lower than 10℃. Near the pole, the temperature in the hottest months in summer is below 0℃, and it is still very cold. Near the polar circle, although the surface ice and snow can melt into swamps in summer, the underlying soil layer is still frozen and becomes permafrost that does not melt all the year round. The polar winter temperature is low, and the highest temperature in Leng Yue is -30 ~-40℃. If there is a blizzard, it will be very cold.
The polar ground temperature is low, and under the cover of polar high pressure, downward flow prevails, with little precipitation. In most areas, the annual precipitation is less than 250 mm Near the polar regions or mainland areas, the precipitation is below 100 mm, and the precipitation is all snow, mostly dry and hard snow particles. Near the polar circle, due to the occasional cyclone invasion, the precipitation increases, which can reach more than 300 mm. Therefore, another feature of the polar climate is dryness and less precipitation.
