What impact do the causes and characteristics of plum rain weather have on us?

What kind of weather is plum rain? In fact, plum rain refers to a process of precipitation, and this kind of precipitation is large-scale precipitation. Plum rain weather usually occurs in Hubei area. Especially at this time of year when spring is about to end and summer is about to come, plum rain weather will appear in Hubei area, and there will be large-scale and heavy precipitation.

What causes the plum rain ? In fact, the plum rain is mainly caused by the accumulation of cold and warm air masses, resulting in large-scale precipitation. The longer this cold and warm air mass lasts, the longer the plum rain weather will last. Therefore, the beginning and end of the plum rain weather are determined by the duration of the cold and warm air masses.

What are the characteristics of plum rain weather

Plum rain weather : Every year between June and July, there is generally a period of continuous rainy weather or concentrated precipitation in the middle and lower reaches of the Yangtze River and the Huaihe River region. During this period, due to the monsoon adjustment of atmospheric circulation, warm and humid air currents from the ocean and cold air moving south from the north continue to interact in the Yangtze and Huaihe River basins, forming an east-west quasi-stationary front, generally called the Meiyu front, causing continuous rainy and concentrated rainstorms. This is the time when plums in the south of the Yangtze River are ripe and yellow, so it is called "plum rain" or "yellow plum weather". Because of the high temperature and high humidity at this time, clothes are prone to mildew, which is also called "mildew rain". During the plum rain season, a stable and long-lasting rain belt is maintained from the Yangtze and Huaihe River basins to southern Japan. The heavy rains in the rain belt are unevenly distributed, and there are often several heavy rain centers. The intensity of the plum rain front's heavy rain is generally much smaller than that of a typhoon, but because the plum rain front lasts for a long time and the heavy rain covers a wide area, the scope of the flood disaster caused is generally larger than that of a typhoon. For example, in 1991, the plum rain season in the Yangtze and Huaihe River basins lasted for about 56 days, and heavy rains and severe floods occurred in the lower reaches of the Yangtze River, Taihu Lake, Huaihe River and other areas. The scale of the affected area, the length of time it lasted, and the severity of the disaster were all rare in history. The Taihu Lake, Lixiahe River, Chuhe River and Qinhuai River areas all reached their highest water levels in history.

If everything goes normally in Hubei, the plum rain weather will generally last for more than 20 days, but there are also special circumstances. According to experts, if the plum rain comes early, it will last longer and the precipitation will be more. Of course, everyone hopes that the plum rain weather is normal and will not last too long. Because appropriate amount of plum rain weather will have a great effect on the growth of rice.
