Climate and disaster occurrence time of the Yangtze River

The middle and lower reaches of the Yangtze River are located in the subtropical monsoon climate zone, and the advance and retreat speed of summer monsoon affects precipitation, which is prone to drought and flood disasters.

In the early summer of each year, under the control of the quasi-static front of the Yangtze River and Huaihe River, "Meiyu" weather appears.

From mid-July to August, the subtropical ridge in the northwest Pacific controlled the "summer drought" weather.

In summer and autumn, the influence of typhoon brings abundant precipitation and relieves the heat.

In winter, strong cold air heading south, or even cold wave, may cause low temperature freezing injury.
