Why is it still so cold?

It is mainly caused by abnormal atmospheric circulation, and the cold and warm airflow is quite active. Last winter and this spring, although the cold air was not very strong, there were frequent activities, and the warm and humid airflow in the south was also strong. The two are "evenly matched" and continue to meet and "kill" in South China and Jiangnan, thus causing continuous low temperature and rainy weather.
