Why is it so hot in Wuhan?

The main reason for the high temperature in Wuhan in summer is that the high altitude in summer is controlled by the subtropical high zone; Secondly, it is the influence of topography. Wuhan is located in the Yangtze River valley with a low altitude. The topography of the valley is like the bottom of a pot, surrounded by mountains, and the ground is difficult to dissipate heat, which makes the temperature rise continuously. Third, these places have dense water networks, a lot of water vapor and high humidity. People are not easy to evaporate after sweating, and the heat dissipation efficiency of sweating is greatly reduced. High temperature and humidity make people feel sultry. Wuhan has a subtropical humid monsoon climate with abundant rainfall and sunshine, and four distinct seasons. The overall climate and environment are good.
