Why is the highest temperature in Mohe 38℃ and Sanya only 35.9℃?
Mohe high temperature reason:
From 165438+2009 10, the polar vortex was obviously abnormal, and the cold air in the Arctic extended to the south, leading to the warmer Arctic and the unusually cold in the middle and high latitudes in the northern hemisphere. Especially after 65438+February, this abnormal feature is more obvious, and it has continued until now, which has promoted the spread of cold air in high latitudes to the south and caused frequent cold air activities in East Asia.
It is summer in the northern hemisphere now, and it is also summer around the solstice. The northern hemisphere has the largest solar altitude angle and the strongest direct sunlight. During this period, there was little precipitation in Northeast China, and the role of rain in regulating temperature was not obvious. The sky was clear, the solar radiation was strong, and the temperature in inland areas rose rapidly. The sub-polar low pressure belt is weak, which leads to the weak polar easterly wind.
