Guangdong: Is the cold air coming? How is the cooling effect?

Guangdong cold air is coming, and the cooling effect is obvious.

According to the weather news in Guangdong, the cold air arrived in Guangdong on the night of September 2 1 2023, and the intensity was weaker than a little. After September 2 1, the highest temperature in various places will drop.

A few days after September 2 1 2023, the subtropical high still strongly controlled Guangdong. On September 22 and September 23, there was weak cold air heading south, but the front area stayed in Lingbei, and there was a small infiltration affecting Guangdong, and the shear line was weak. On September 22 and September 23, the east wind oscillated westward, but there was no humidity field to cooperate with it, and the water and gas conditions were poor. The heat is accompanied by the rhythm of sporadic thunderstorms, and thunderstorms are accompanied by short-term heavy precipitation and short-term strong winds.

From the intensity point of view, this cold air is not strong, but it coincides with the stability and intensity of the subtropical high, abundant water vapor conditions and high heat in the south, and the intense action of cold and warm air, which leads to tornadoes and typhoon-level Jianghuai cyclones in Suqian and Yancheng, Jiangsu Province. Under the influence of cold air and rainy weather, many places in the south also experienced seasonal cooling overnight. The temperature in Wuhan and Changsha dropped by about 13℃, giving people an illusion of autumn.
