When will the rainy season in Jiangnan end?
Although Meiyu is a unique weather and climate in the middle and lower reaches of the Yangtze River, its appearance is not isolated, but closely related to the north-south displacement of a large-scale rain belt.
In the east of China, east of 1 10E, during the flood season from mid-May to early June, the main rain belt swings in Nanling Mountains and its south. In recent years, although it moved to the north of Nanling within a certain period of time, it often stayed in the south of 28N and 29° n from a waiting period (5 days) or the multi-year average of 10 days. This period is called Jiangnan rainy season or South China pre-flood season.
In the middle and late June, the main rain belt moved northward within the range of 29° n-33° n (that is, Yichang in the west, the Yangtze River estuary in the east, and then across the sea to Japan; From the two lakes plain in the south to the south bank of Huaihe River in the north, it is stable and less moving. At this time, the area south of Nanling is outside the rain belt, and the rainy weather is over; The middle and lower reaches of the Yangtze River bid farewell to the sunny early summer and ushered in the rainy season. Heavy rain and rainstorm appeared from time to time and lasted until the beginning of July. This is a famous rainy season in the middle and lower reaches of the Yangtze River.
From mid-July, the rain belt moved northward again, reaching the area north of 33 N. Stagnation and wandering in the Yellow River, Huaihe River Basin, North China, Northeast China and other places have caused heavy rainfall again and again, which are called Huanghuai rainy season and North China rainy season respectively. At this time, the plum rains in the middle and lower reaches of the Yangtze River ended, the sun hung high and entered the hot summer season. This kind of weather will last until the end of August, and then the rain belt will quickly withdraw southward with the gradual activity of cold air. In less than a month, the rain belt will always retreat to the coastal areas of South China. The regular change of this rain belt shows that the plum rain in the middle and lower reaches of the Yangtze River is not an isolated and local weather and climate phenomenon, but an integral part of the main rainy season activities in eastern China, which reflects the stagnation of the main rain belt in the middle and lower reaches of the Yangtze River.
I don't know where you are from, but you can sit down accordingly.
Question 2: When will the rainy season in the south end? The Central Meteorological Observatory released the weather trend forecast for the next ten days on March 4, 2009 10: It is estimated that there will be frequent cold air affecting China in the next 10, and the weather in the northern region will be changeable. 7 days ago, there were rainy (snowy) weather in Jiangnan, South China, Sichuan Basin, Guizhou and other places, and rainfall was conducive to alleviating the drought in meteorological arid areas such as southern Jiangnan and South China. There is much rain in South China when early rice is sown and raised, and the temperature will be 2 ~ 4℃ lower than normal. In some areas, the daily average temperature will be lower than 65438 02℃ for 3 ~ 4 days, which will adversely affect spring sowing. On August 8- 10, the rainfall intensity in Jiangnan and South China will obviously weaken, and it will turn from sunny to rainy. The specific forecast for the next 4 ~ 10 days is as follows: from 08: 00 on the 7 th to 08: 00 on the 8 th, there will be small to moderate rain in most parts of the south of the Yangtze River and central and eastern South China, and heavy rain in some parts of South China; * * * There is light snow (rain) in the east and west of Xinjiang. From 08: 00 on the 8 th to 08: 00 on the 9 th, there were small to medium snow (rain) in northern Xinjiang, northeastern Inner Mongolia and northeastern Shandong Peninsula, and there were 4 ~ 6 northerly or southerly winds, and the temperature showed a downward trend; There is light rain in the south of the Yangtze River, north-central South China, Guizhou and southeast of * * *. From 08: 00 on the 9th to 08: 00 on 10, there was light rain in southern Jiangnan, central and western South China, eastern Sichuan Basin and Guizhou. There is light snow (rain) in northern Xinjiang, eastern northwest and eastern northeast. From 00: 00 on 10 to 08: 00 on10/0, there was a small to medium snow in the north of Xinjiang, and it turned north to 4 ~ 6, and the temperature dropped; There is light rain in the middle and upper reaches of Hanshui River, western Jiangnan, western South China, Sichuan Basin and Guizhou. There is light snow (rain) in the east of Qinghai-Tibet Plateau. On June 5438+0 1- 13, there will be a large-scale precipitation cooling process in the central and eastern regions.

Question 3: When will the rainy season in the south end (indicate the beginning and end of the month)? 10. Generally, the rainy season in the south begins in June and ends in September, with less in mid-July and August. But this year may last for a long time, because of the influence of El Nino, there may be more precipitation and the duration will be longer. The reporter learned from the National Climate Center of China on June 5438+05 that El Niñ o has increased significantly recently, and the seawater temperature in the equatorial Middle East Pacific has reached a new high since this El Niñ o event. Zhou Bing, chief climate monitoring expert of China National Climate Center, said that recently, the abnormally warm water in the Pacific subsurface near the equator spread eastward and gradually rose to the surface. Monitoring shows that the SST in the equatorial Middle East Pacific was higher than normal in April 1 degree Celsius, and further higher in early May, setting a new high since the El Niñ o event in May last year. Zhou Bing predicted that this round of El Niñ o events will last until summer and autumn, and the trend of "flooding in the south and drought in the north" in flood season in China is becoming more and more obvious. It is estimated that this summer, the precipitation from the Jianghuai Basin to the south of the Yangtze River will be more than normal, and floods will occur in some areas; The precipitation in North China is less than normal, and the drought is heavier. The number of typhoons affecting China is less than normal, but the average intensity is higher.
Question 4: When is the rainy season in the south of the Yangtze River, such as Jiangsu and Zhejiang? The precipitation in the two lakes in the south of the Yangtze River increased obviously. Since late April, spring rain has prevailed in the coastal areas of South China, and from May to June, rain areas are all over the south of the Yangtze River. The middle and lower reaches of the Yangtze River generally enter the rainy season from the middle and late June to the middle and early July.
Question 5: Why is the rainy season in Jiangnan called Huangmei Season, and plums are yellow in late spring and early summer?
Every year around the Dragon Boat Festival, the Yangtze River and Huaihe River enter Mei, and then it will rain for about a month.
Question 6: In the rainy season in the south, the precipitation in the two lakes in the south of the Yangtze River increased obviously. Since late April, spring rains have prevailed in the coastal areas of South China, and rainy areas are all over the south of the Yangtze River from May to June. The middle and lower reaches of the Yangtze River generally enter the rainy season from the middle and late June to the middle and early July.
Question 7: How long is the rainy season in the south? The rainy season in the south generally begins in June and ends in September, with less in July and August.
But this year may last for a long time, because of the influence of El Nino, there may be more precipitation and the duration will be longer.

Question 8: How long is the rainy season? When does it start and end? With the different regions, the time is different after a long time, and there is no specific time. It's probably the season when plums are ripe.
Meiyu is a unique weather and climate in the middle and lower reaches of the Yangtze River, but its appearance is not isolated, but closely related to the north-south displacement of a large-scale rain belt.
In the eastern part of China, east of 1 10 E, the main rain belt swings in Nanling Mountains and its south area during the flood season from mid-May to early June. In individual years, although it moved to the north of Nanling in a certain period, it often stayed in the south of 28°-29° N according to a waiting period (every 5 days) or the multi-year average of 10 days. This period is called Jiangnan rainy season or South China pre-flood season.
In the middle and late June, the main rain belt moved northward within the range of 29-33 N (that is, from Yichang, China in the west, to the Yangtze River estuary in the east, and then across the sea to Japan; From China Lake Basin in the south to the south bank of Huaihe River in the north), it is stable and less active. At this time, the area south of Nanling is outside the rain belt, and the rainy weather is over; The middle and lower reaches of the Yangtze River bid farewell to the sunny early summer and ushered in the rainy season. Heavy rain and rainstorm appeared from time to time and lasted until the beginning of July. This is a famous rainy season in the middle and lower reaches of the Yangtze River.
Beginning in mid-July, the rain belt moved northward again, reaching the area north of 33 N, and stopped and wandered in the Yellow River, Huaihe River Basin, North China and Northeast China, causing heavy rainfall again and again, which were called Huanghuai rainy season and North China rainy season respectively. At this time, the plum rains in the middle and lower reaches of the Yangtze River ended, the sun hung high and entered the hot summer season. This kind of weather will last until the end of August, and then the rain belt will quickly withdraw southward with the gradual activity of cold air. In less than a month, the rain belt will always retreat to the coastal areas of South China. The regular change of this rain belt shows that the plum rain in the middle and lower reaches of the Yangtze River is not an isolated and local weather and climate phenomenon, but an integral part of the main rainy season activities in eastern China, which reflects the stagnation of the main rain belt in the middle and lower reaches of the Yangtze River during its northward movement.
Question 9: When is the rainy season? The arrival time of rainy season is different in different areas, which is related to the passing of rain belt in China.
On average, from February to May every year, the main rain belt is located in the coastal areas of South China, and it slowly moves northward with the seasonal warming. In the middle and late June, the rain belt moved northward to the Yangtze River basin, which made the Jianghuai area enter the meiyu period, and the continuous rain will last until the beginning of July. In early or mid-July, the rain belt moved northward to the Yellow River basin, and the Jianghuai area was controlled by the subtropical high and entered the summer drought period. If the subtropical high is strong and lasts for a long time, it will be very hot and rainy for a long time, resulting in severe drought. On the south side of the subtropical high is the easterly belt, where easterly waves, tropical storms and even typhoons often occur. So after mid-July, rainy areas appeared again in South China. From the end of July to the beginning of August, the rain belt moved northward to North China and Northeast China, reaching the northernmost position in a year. If the subtropical high is stable, the summer drought weather in Jianghuai area will continue with high temperature and summer heat. From the end of August to the beginning of September, the rain belt began to withdraw rapidly southward with the activity of cold air in the north, and the rainy season in North China and Northeast China ended at the earliest. In the first ten days of 10, the rainband retreated to the south of the Yangtze River and then withdrew from the mainland, ending the one-year cycle of rainband movement.
