Why is it not hot in the south this year?

Hello, landlord (emotional assistance inquiry group). I'm glad to answer your question: since the spring, there have been three cold wave weather processes. The frequent invasion of cold air to the south has led to the continuous low temperature in southern China such as Fujian and Guangdong. Xiao and other experts believe that the main reason for the frequent cold air activity in middle and high latitudes since winter is related to the location of polar cold air. Since June 5438+065438+ 10, 2009, the polar vortex has been obviously abnormal, and the cold air in the Arctic has spread southward, resulting in a low temperature in the south.
