6 meters low, the water level in the Wuhan section of the Yangtze River is the lowest time since there are hydrological observation records

The Yangtze River Daily Da Wuhan Client August 13 (Reporter Song Lei Correspondent Guo Yujun) This summer, the Yangtze River is no longer as magnificent as in previous years, but retreats. Why is it so low!

Real -time water love data shows that as of 19:00 on August 13, the water level in Wuhan in the Yangtze River was 17.54 meters, which was 5.94 meters lower than the water level in the same period. The current water level in the Wuhan section of the Yangtze River is the lowest water level in history since 1865.

Hankou (Wuhan Pass) was completed in 1865. This is the earliest modern hydrological station in the country with continuous system data. The comparison of the history of hydrological observations corresponds to the "day". According to hydrological observation records, the lowest level of the water level in the Wuhan section of the Yangtze River appeared on August 30, 1972, 16.93 meters; on August 13 of that year, the water level in the Wuhan section of the Yangtze River was 20.25 meters.

This year, the highest water level in the Wuhan section of the Yangtze River appeared at 21:00 on June 9 at 24.96 meters, approaching the water prevention level. After that, the water level has slowly fell continuously. Except for the Wuhan section of the Yangtze River, the water level of the Hanjiang River and Lianjiang is generally low. The water level of Hanjiang Xintou Station is 18.13 meters (8 o'clock on August 12), which is 6.05 meters lower than the water level in the same period.

The first -level hydrophilic platform of Hankou River Beach is no longer covered by water. The river surrounding the rivers around the south bank retreats to exist in a large area of ​​beaches. Why did the rare phenomenon of "anti -dry period" in the upper reaches of Tianxingzhou occurred?

On the 13th, relevant experts from Wuhan Flood Control and Drought Resistance Headquarters pointed out that this was caused by large -scale abnormal climate that appeared after summer, mainly because the rainfall was significantly less, and the high temperature evaporation volume continued to increase.

Experts pointed out that in July, the rainfall in the Yangtze River Basin was significantly less. The monthly precipitation was 34%less than the average value of 30 years (1991-2020). Among them, the upper reaches of the Yangtze River was 39%, and the middle and lower reaches were 28%. The water in the Wuhan section of the Yangtze River was significantly reduced. The amount of water from Hankou Station in the middle reaches of the Yangtze River was 59.184 billion cubic meters, which was 18%less than the 30 -year average. 43%; the average flow of Danjiang Pass was 510 cubic meters per second, 74%less than the 30 -year average. The main reason for the less precipitation is Meiyu and Typhoon abnormalities. This year, the rainy period of Mei Rain has a short duration, and some areas are almost "empty plums". The typhoon in July and August failed to go deep into the inland and no precipitation.

At the same time, the Yangtze River Basin has continued to have high temperatures since July 9, and it is expected that high temperatures will continue for several days. Continuous sun and hot weather brings high evaporation phenomenon in water such as the Yangtze River.

Data show that the water level of the Yangtze River and Dongting Lake and Poyang Lake are 4.7 meters to 5.7 meters lower than the same period. According to meteorological predictions, most of the Yangtze River Basin will maintain high temperature and rainy weather in the next week, and the water level of the Yangtze River will continue to decline. Sichuan, Chongqing, Hubei, Hunan, Anhui, Jiangxi and other places may continue to develop.
