Why is it easy to have "freezing rain" in Guizhou in winter?
These are the reasons why it rains in winter. Guizhou province is located in China's subtropical monsoon climate zone, and its winter location happens to be the intersection of southeast monsoon, southwest monsoon and northwest monsoon. Cold and warm air meet here, often evenly matched, which causes long-term rainfall. Such conditions are the first step in causing freezing rain.
Secondly, because Guizhou is located in the plateau, the weather is colder than that in the same latitude area. Take Guiyang as an example, the average temperature in winter is only 5 degrees, and it often hovers at 0 degrees in case of cold wave, which is the second step to cause freezing rain.
Thirdly, because the cold and warm air forms a quasi-static front here, the warm air is lighter in the upper part and the cold air is heavier in the lower part, so the temperature in the cloud is even higher than that near the ground. Therefore, when clouds cause rainfall, raindrops do not form ice crystals at high altitude, but exist in the form of small water droplets. In the process of falling, the temperature of water droplets decreases due to the temperature drop. But if the water drops fall to the ground before freezing, it will form freezing rain. In Guizhou, because of the high terrain, the clouds are far from the ground.
In a word, because its topography, geographical location and water vapor conditions are isomorphic conditions for the formation of freezing rain in Guizhou, Weining County in Bijie Prefecture of Guizhou Province is known as the "hometown of freezing rain in China".
