Why is the temperature difference so great in summer in Hunan?

The main reason for the large temperature difference in summer in Hunan is that Hunan is located in the subtropical monsoon climate zone, which is affected by extreme weather such as rainstorm, lightning and high temperature. At the same time, the topography and landforms are complex, resulting in great differences in temperature and humidity between different regions.

Today, during the daytime, the temperature in sunny Wan Li, Hunan Province is relatively high, but at the same time, there will be local heavy rainfall or thunderstorm weather, which can make the temperature drop sharply and form an obvious temperature difference.

At night, due to the low terrain in Hunan and the existence of the Hunan Basin, the temperature drops rapidly at night, resulting in a great temperature difference between day and night.
