Why is Jiangyin so cold?

Since the winter of this year, there has been rain and snow in a large area of the country, and the humidity in the air is relatively high, so it will feel particularly cold.

There is no freezing rain this year. If you have paid attention to the weather forecast of CCTV 1 before, you will know that freezing rain often occurs in China's Guizhou, Jiangxi and other places in winter and spring, but it is very rare that freezing rain lasts for such a long time this year.

Freezing rain is a weather phenomenon seen in early winter or late winter and early spring. When the strong cold air meets the southbound warm and humid airflow, the cold air is inserted under the warm air like a wedge, and the near-surface temperature drops below zero, and the humid warm air is lifted to form clouds, causing rainfall. When raindrops fall from the air, because the temperature near the ground is very low, a layer of crystal clear thin ice will form on the surface of telephone poles, trees, vegetation and roads, which is called "freezing rain" in meteorology.
