Reasons for the recent temperature drop in Suqian

Jianghuai, Jiangnan and other places have had more precipitation since winter, and the temperature in the south continues to be low. The lowest temperature in many areas has set a record for the same period in history. The above-mentioned climate anomalies occurred against the background of large-scale climate anomalies in the northern hemisphere.

Since the autumn of 2009, the cold air in the Arctic has been southward, with strong force, frequent activities and southward invasion. The cold air in Eurasia is located to the east, and the strong cold air keeps accumulating in Siberia, and continues to split and spread to the south, affecting China, and meeting with the warm and humid water vapor transport in the south. This year, it is extremely active, resulting in frequent low-temperature rain and snow weather in North China and South China.

Recently, cold air frequently goes south, meeting with the unusually active warm and humid airflow in the south, causing continuous rain in the coastal areas of Jiangnan and South China. The intense cooling effect of cold air and continuous rainfall leads to extremely low temperatures in these areas. (
