I believe that people who live in Changsha must have a general understanding of the topography of Changsha. Changsha is located in the south of China, surrounded by mountains on three sides and hilly areas on the east, so the terrain of Changsha is relatively flat. The pleasant climate of Changsha in the plain area is also closely related to the local topography.
Because it is surrounded by mountains, the cold air is isolated from the outside world every winter, so the winter in Changsha is not as bitter as that in other places. In addition, the local climate has the function of river conservation, which makes people breathe smoothly in such an environment. In contrast, the local climate in summer is not too hot. Although there are hills around, the monsoon climate can still climb over these low hills and enter the Changsha Plain. At the same time, the monsoon climate also brings abundant rain. So it often rains in Changsha in summer, and there is little heat left under the erosion of rain. On the contrary, the water towns in the south of the Yangtze River have a taste of water towns.
However, the temperature difference between day and night in Changsha is a thorny issue. Someone once joked that one day in Changsha is the fourth grade in the north, and it is a little chilly in the morning. At noon, the temperature rises and looks hot, and at night, the temperature drops, and the air looks bitter. This is also a headache for many people. Although it is located in the south of China, due to the influence of topography and other factors, this geographical position does not make Changsha very different from the north. On the contrary, it is more like a transitional zone between north and south, hot and cold.
It's the kind that opens very early
