Nanchang is surrounded by mountains on three sides, Jinggangshan in the west, Wuyishan in the east and Nanling in the south. The subtropical monsoon (southeast wind) that brings us coolness is repelled by these mountains. Without the wind, hot air will gather slowly and will not disperse for a long time.

2, the humidity is too high

Another reason why Nanchang is very hot in summer is the high humidity. Originally, because there was no wind, the hot air could not disperse, and the humidity in the air was too high, so our sweat could not volatilize, and the moisture would stick to us with the hot air. This is the sultry weather we often encounter, just like taking a sauna.

3. Urban heat island effect

With the acceleration of urban construction in Nanchang, more and more high-rise buildings have sprung up. These buildings absorb a lot of heat, which leads to the increase of surface temperature. At the same time, the building density is very high, so we have to walk through these high-temperature cement forests every day.

Nanchang belongs to subtropical monsoon climate, with humid and mild climate, abundant sunshine, long summer and winter and short spring and autumn. Nanchang is a typical "hot summer and cold winter" city. It's hot in summer, so it's called a stove. It's colder in winter. Annual average temperature 17℃- 17.7℃, extreme historical maximum temperature 40.9℃, extreme historical minimum temperature-15.2℃.

Nanchang is located in the subtropical zone of the northern hemisphere and influenced by the East Asian monsoon, forming a subtropical monsoon climate. It is windy in winter and southerly in summer. The city is rich in heat, abundant in rain and sunshine, and the rain and heat match well in the peak season of crop growth, which provides favorable meteorological conditions for agricultural production and is known as the land of plenty.

However, due to the different monsoon intensity, different advance and retreat times, the temperature changes greatly, the precipitation distribution is uneven, and meteorological disasters such as high temperature drought, low temperature snowfall and low temperature chilling injury, rainstorm and flood, typhoon and so on frequently occur, which have adverse effects on people's production and life.
