China Weather Network News "Pouring Yellow Plum" is coming! Today (August 10) to 14, there will be heavy rainfall along the middle and lower reaches of the Yangtze River along the river to the northern part of Jiangnan, and there will be heavy rain or even heavy rain in Hubei, Anhui, Jiangsu, Zhejiang, Shanghai and other places. The continuous rain seems to have turned back to Huang Meitian and returned to the middle and lower reaches of the Yangtze River. What is "inverted yellow plum"? What is the impact of "pouring yellow plum"? What precautions do I need to take? China Weather Network for you to interpret in detail.
What is the difference between "pouring yellow plum" and plum rain Why is there "pouring yellow plum" this year?
Today to the 14th, the middle and lower reaches of the Yangtze River along the river to the north of Jiangnan will have heavy rainfall, the strongest rainfall period appears on the 11th to the 13th, the precipitation lasts for a long time, the cumulative rainfall is large, and the familiar plum rainy season in Jiangnan and other places seems to be coming back.
"Inverting Yellow Plum" is to point out that after the plum, the meteorological elements in the middle and lower reaches of the Yangtze River have taken on the characteristics of mid-summer, experiencing a period of sunny, hot and high temperature weather, and then turning into a weather with plum rain characteristics, as if Huang Meitian is walking back to the middle and lower reaches of the Yangtze River.
According to Wang Weiyue, a meteorological analyst at the China Weather Network, generally speaking, the "pouring yellow plum" does not last long, from a week or so to ten days and a half months. The precipitation in the rainy season is caused by the plum rainy front, and the cold air and warm and humid air flow that continue to move south in the north have been facing each other for a long time in the middle and lower reaches of the Yangtze River, and the rainy weather may last for about a month or even longer.
Why is there a "poured yellow plum" this year? Wang Weiyue analyzed that "inverted yellow plum" is a manifestation of climate anomalies, often with continuous rains and even rain, and obvious cooling. This year, the position of subtropical high pressure is abnormally swinging, and in the next few days, the south fall of subtropical high pressure will just allow cold and warm air to meet again in the middle and lower reaches of the Yangtze River, resulting in the appearance of "inverted yellow plum".
The "inverted yellow plum" in the middle and lower reaches of the Yangtze River lasted for five days Jiangsu, Zhejiang, Shanghai and other places suffered heavy rainfall
Wang Weiyue analyzed that the early stage of this rainfall process was caused by low vortex shear lines, and after the 12th, with the addition of cold air and the strengthening of the rapids, the intensity of rainfall increased significantly.
Specifically, the Central Meteorological Observatory predicts that tomorrow, the precipitation in the middle and lower reaches of the Yangtze River will still be relatively scattered, and there will be moderate to heavy rain in some parts of Jianghuai, Jianghan, and jiangnan in the north and central parts of the country, among which there will be heavy rain or heavy rain in southern Jiangsu, south-central Anhui, eastern and southwestern Hubei, northeastern Jiangxi, Chongqing and other places.
From the 12th to the 13th, the precipitation along the middle and lower reaches of the Yangtze River increased significantly, and there was heavy rain in the central and southern parts of Jianghuai, northwest and northeast Of Jiangnan, and heavy rain or even heavy rain in Chongqing, eastern Hubei, southern Anhui, southern Jiangsu, northern Zhejiang, Shanghai and northern Jiangxi.
On the 14th, there was heavy rain along the middle and lower reaches of the Yangtze River and parts of eastern Guizhou, and there may be heavy rain in northern Zhejiang, northeastern Jiangxi, southern Anhui and parts of the junction of Guizhou and Hunan. On the 15th, the precipitation area was pressed south, and the precipitation intensity weakened significantly.
The middle reaches of the Yangtze River should beware of drought and floods turning sharply The lower reaches of the Yangtze River should pay attention to flood prevention and flood prevention
Wang Weiyue reminded that since June, there has been a moderate meteorological drought in some parts of Hubei, Hunan, Jiangxi and other provinces in the middle reaches of the Yangtze River, and this rainfall is beneficial to alleviating high temperature and drought, increasing the storage of water in kutang and increasing soil moisture in drylands, but due to the long duration of rainfall and the large cumulative rainfall, there may be a sharp turn of drought and flood in the local area.

In the lower reaches of the Yangtze River, affected by typhoon "fireworks", since June, the rainfall in Zhejiang, Shanghai, Anhui, Jiangsu and other places has been 20% to 50% more than the same period of the year, and it is necessary to pay attention to the superimposed impact of heavy rainfall. The meteorological risk of the main stream of the lower reaches of the Yangtze River and some small and medium-sized rivers is high, especially some hydrological stations in the Taihu Lake Basin are still above the alert water level, and it is necessary to strengthen the monitoring of rain and water conditions.
Affected by heavy rainfall, the meteorological risk of flash floods, geological disasters, small and medium-sized river floods, and flooding disasters in the south and northeast of Chongqing, the northeast of Hubei, the western and eastern parts of Anhui, the northeast of Jiangxi, and the southwest of Jiangsu is high, and it is necessary to strengthen prevention and do a good job in urban flood prevention and flood prevention and safety management.
