Climate characteristics of Nanchang:

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.

Annual rainfall 1600- 1700㎜, precipitation days 147- 157 days, annual average rainstorm days of 5.6 days, and annual average relative humidity of 78.5%.

The annual sunshine hours are 1723- 1820 hours, and the sunshine rate is 40%, with the maximum in July and August and the minimum in February and March. The light distribution is basically synchronized with the peak season of crop growth, which is beneficial to agricultural production.

Solar radiation Nanchang is the secondary station of solar radiation observation, which carries out total radiation and net radiation observation. The average total radiation from 1986 to 2003 was 4279.02 MJ/m2, and the average net radiation from 1992 to 2003 was 2078.67 MJ/m2.

Because the wind is greatly influenced by topography and geographical location, Nanchang, Xinjian and Jinxian are close to Poyang Lake, and the wind is strong, which belongs to the wind energy utilization area; Anyi doesn't face Poyang Lake, except for the special terrain, the wind is useless, and the annual average wind speed is 2.3m/s ... The frost-free period of the whole year is 25 1-272 days. Suitable for the growth of plants and flowers, it is an ideal area for building a "garden city".
