When does the southern rainy season end? What month is the southern rainy season?

The recent rain has really affected everyone's mood. Geological disasters have occurred in some places in the south because of the rain, but you don't have to worry too much. The rainy season will soon pass, and you will welcome summer after this rainy season has passed.

The annual plum blossom time

July 9th

A period of continuous rainy weather with heavy precipitation and frequent precipitation often occurs from the Jianghuai Valley in China to the early summer in southern Japan.

It is named because the plum is yellow and ripe. Because of the high temperature, heavy humidity and heavy rain at this time, utensils are easy to get wet and mildew, so it is named mildew rain.

generally, plum blossoms enter from early June to mid-June, and begin in midsummer after early July.

Types of Meiyu

1. Normal Meiyu

The southern region starts around June 15th and ends around July 15th. The rainy season lasts about 2-3 days, and the rainfall is maintained around 2-4 mm, so the rainy season is normal.

2. Early Meiyu

If a year has plum rains that appear at the end of May and the beginning of June, it means early Meiyu

3. Late Meiyu

Plum rains that appear around June 15th are called late Meiyu.

4. Extra-long Meiyu

The rainfall from May to July reached an abnormal 9 mm, which is called extra-long Meiyu.

5. Short plum and empty plum

Some plum rainy seasons appear for a very short time, leaving only ten days, or there is no plum rainy season at all.

6. There is no plum rainy season at the beginning, and there is a hot climate in summer, but suddenly there are all kinds of thunderstorms and rains.

Pruning criteria

During June and July, on the 5mb map in the northern hemisphere, 125-14. The position of the ridge line of the western Pacific subtropical high of E: 23-24.n in southern Zhejiang and 24——25.C in northern Zhejiang, and it has been stable for five days or more.

It appears after the continuous rainy days:

It lasts for seven days or more in southern Zhejiang and five days or more in northern Zhejiang.

the daily average temperature is stable at or above 25.C The daily average temperature and pressure time curve of a single station have synchronous rise. If the subtropical ridge line has jumped north to 25. N。

if it is stable for two hours, and the continuous rainy weather is greater than or equal to .1 mm during this period, the whole day with daily rainfall greater than or equal to 1. mm will be selected.

Is the weather good after the rainy season?

After the rainy season, it will be 12-13. The ridge line of subtropical high between E jumps northward to 26. N or its north, and the daily average temperature is ≥27.C, the highest temperature is 33.C, and there is no rain for more than 6 consecutive days. The average annual date of plum blossom is July 9.

when the ridge line of subtropical high jumped northward to the north of 26.N and remained stable for more than 3 days, the last provincial precipitation process that the peripheral line of subtropical high (588dagpm) controlled Hankou for more than 2 days ended, and it was designated as plum blossom.
