Climate of Jinchang Economic and Technological Development Zone

Jinchang's four seasons climate belongs to continental temperate arid climate. There is plenty of sunshine, dry climate, year-round north wind, large temperature difference between day and night, four distinct seasons, long frost period and windy spring.

The temperature in the territory is high in the north and low in the south, with less precipitation in the north and more precipitation in the south. From northeast to southwest, it can be roughly divided into five climate zones, namely, mild extreme drought zone and warm cool drought zone; Warm, cold and arid areas; Cold semi-arid area and cold semi-humid area; Cold and humid areas; Cold and humid areas and cold and very humid areas.
