From 3331 to 600, the water area of Poyang Lake has reached the minimum value of nearly 10 years!Why "thin into a lightning"?

Affected by the early high temperature and drought, the large lakes such as Dongting Lake and Poyang Lake in the Yangtze River Basin once changed from sparkling from the lake to the currently exposed grassland. Especially under the high temperature burning in mid -to -late August, Poyang Lake has lost thinning into a "lightning". Whether the water level can be restored in the short term has become the focus of many netizens.

On August 29, the Red Star reporter learned from the China Meteorological Administration that according to the monitoring of Fengyun Meteorological Satellite, on August 21, 2022, the main body of Poyang Lake and the nearby waters were 939 square kilometers, which was partially in the same period (average of 3110 square kilometers) partially partially partially partially partially partially partially partial). 70 % of the small water, the largest water area monitored on June 27th, has decreased by 7.2 % to the minimum value in the past 10 years.

The China Meteorological Administration also clearly stated that in August, the phenomenon of "flooding during the flood season" was exposed in Poyang Lake and the river, which was not normal.

↑ Affected by the high temperature and rainy weather in the day, the water level of Poyang Lake, the largest freshwater lake in China, continued to decline.

Fengshui period becomes dry period

The area of ​​Poyang Lake "shrinks" to the minimum value of nearly 10 years

Red Star reporter learned from the China Meteorological Administration that according to the monitoring of Fengyun Meteorological Satellite, on August 21, 2022, the main body and nearby waters of Poyang Lake were 939 square kilometers, which was 70 % of the same period (average 3110 square kilometers), and the phase was phased. Compared with the maximum water area monitored this year on June 27, it has decreased by 7.2 %, the minimum value in the past 10 years.

According to the "Jiangxi Daily" on August 22, the overall water body area of ​​Poyang Lake has shrunk to less than 600 square kilometers. On August 4, the data of the Ministry of Water Resources also showed that the water level of Poyang Lake had decreased to the duvil period standard, and the arrival of the dry period was more than 100 days earlier than previous years.

Red Star reporter learned that this year is the earliest year since the hydrological records entered the dry period. According to the records, in recent years, Poyang Lake's dry period is generally from October to November. From early July to mid -August, it should actually be the rich water period of Poyang Lake, and until late October to early April of the following year, it is the dry period of Poyang Lake.

During the flood period of anti -dead system

China Meteorological Administration: High temperature drought is the main reason for the main reason

Regarding the sharp decline in the water area of ​​the Poyang Lake, the China Meteorological Bureau also made it clear that the phenomenon of "anti -drying during the flood season" such as Caozhou and River in Poyang Lake in August is not normal.

High temperature is an important reason for the anti -dead period of the flood season. According to the statistics of the China Meteorological Administration, as of 7:00 on August 24th, Jiangxi Province, where Poyang Lake is located, a total of 91 counties (cities, districts) have a maximum temperature of more than 35 ° C. Among them, the maximum temperature of 91 counties (cities, districts) exceeds 37 ° C, and the maximum temperature of 53 counties (cities, districts) exceeds 40 ° C. The highest at 42.6 ° C in Xiushui County, Jiujiang, and broke the record of the Jiangxi Provincial National Station since 2003.

According to the latest report released by the World Meteorological Organization, in July this year, it has become one of the three hottest July since the meteorological records. This year's extreme high temperature process has occurred under the background of the global subtropical high -pressure abnormal atmospheric circulation. Recently, the northern hemisphere subtropical high -pressure high -pressure is extremely powerful, almost around the earth for a week.

The China Meteorological Administration responded that the auxiliary tropical high pressure was abnormal and strong is the most direct and most important reason for drought. The Western Pacific Deputy High High High High High High and Stable and Maintaining Time, the control range after merging with the mainland is wider. Especially since August, the strength of the high -pressure center has increased rapidly, and the control scope of the control includes the middle and lower reaches of the Yangtze River and its north.

Jiangxi starts the fourth emergency response of meteorological drought

There will be 3 precipitation process in September

Affected by the continuous high temperature, the Jiangxi Provincial Meteorological Bureau has launched a four -level emergency response to major meteorological disasters (meteorological droughts).

In this regard, the Jiangxi Meteorological Department has continued to pay attention to the changes in the weather situation, deployed early, and linked up and down to closely monitor the development of high temperature and drought, strengthen monitoring and early warning and discuss judgment, and make every effort to ensure services.

At the same time, Nanchang City also urgently held the city's artificially influencing and drought resistance scheduling meeting. Jiujiang City also issued a timely high temperature and drought warning signals to spread the latest forecast and early warning information and preventive response to the latest forecast and early warning information and preventive response to channels such as broadcasting, television, Weibo, WeChat, and mobile phone SMS. The Agricultural Gas Center issued a special report of agricultural meteorological services to guide the city's high -temperature drought resistance work in the city.

So, what is the future weather trend? According to the China Meteorological Administration, it is expected that from the end of August to mid -September, the average temperature of the province in Jiangxi is 25.5 ° C to 26.0 ° C, which is 0.5 ° C to 1.0 ° C higher than the same period. Among them, from 27.0 ° C to 27.5 ° C in central Gan and Gan, both, both are 0.5 ° C to 1.0 ° C; Gannan 26.5 ° C to 27.0 ° C, high 0 ° C to 0.5 ° C. In late August, the extreme maximum temperature in some areas will be 38 ° C to 39 ° C, and the local area can reach 40 ° C.

However, extreme high temperature and drought weather has eased in late August, and it is expected that there is no large -scale high -temperature weather development in mid -September.

From the long -term impact, due to the continuous precipitation in the early stage, most of the weather drought spread in Jiangxi. 3 precipitation process will occur in September, mainly from September 3rd to 5th, 11th to 12th, and 27th to 29th, which is conducive to improving the water environment and ecological environment of the lake, but you should also pay attention to the influence of waterlogging after drought to prevent the influence of waterlogging and prevent the prevention of water flooding to prevent the prevention and prevention. Strong lightning weather such as lightning lightning, thunderstorms and short -term heavy rainfall.
