Recently, there have been heavy snowstorms in Heilongjiang and other places. What is the weather like in the south?

Strong cold air southward brought snowfall to central and southern Inner Mongolia, western Liaoning, western and northwestern Jilin, southeastern Heilongjiang and other places, and unexpected warming occurred in many cities in the south. The temperature in many cities has reached 30 degrees Celsius, as if it had returned to summer overnight. After working for a period of time, the northern region finally ushered in snowfall. Because the temperature was higher before the arrival of strong cold air, the snowfall intensity was also relatively high. In Tongliao, Inner Mongolia, it is also a scene of heavy snow closing the door. Some netizens posted videos that were difficult to move in the snow, and some friends with weak bodies could only go with the wind.

China has a vast territory, and there are many kinds of climates on the vast land. From north to south, the climate in China is temperate monsoon climate, temperate continental climate, subtropical monsoon climate, plateau mountain climate and tropical monsoon climate. Monsoon climate is characterized by the same period of rain and heat, and so is China. Winter in the north is cold and dry, the temperature is below zero, and winter in the south is mild. In winter, there is central heating in the northern region, and the average indoor temperature is above 22 degrees Celsius, which is very warm. Even in rural areas, there is no need to worry about heating. The heating effect of northeast kang is very good. Among them, the most helpless should belong to several provinces in the central region, which are located at the junction of north and south. Their winter is inseparable from thick quilts and air conditioners or electric heaters.

It seldom snows in winter in the south unless the climate is abnormal, such as the once-in-a-century snowstorm in 2008. In summer in China, the temperature is generally high all over the country, except the Qinghai-Tibet Plateau, which is particularly high above sea level, so the summer temperature is around 10 degrees, which means that the rest areas are above 20 degrees Celsius. With the precipitation of high temperature, the summer monsoon affecting China is southeast wind. This is because the specific heat capacity of land and ocean is different, so the rapid warming of land in summer is low pressure and the ocean is high pressure, and the wind blows from high pressure to low pressure, that is, from land to ocean. The wind also brought a lot of water vapor from the sea, and the movement of rain belt from south to north brought a lot of precipitation to the monsoon region of China.
