Is there any inevitable connection between the Three Gorges of the Yangtze River and the dry weather and no rain?
After the Three Gorges Project was built, a huge water body was formed in the east of Sichuan Basin. During the water storage period, due to the height of the dam reaching175m and the daily water storage reaching135m, the water temperature of the reservoir is heated up, the water vapor evaporates, the atmosphere is heated and expanded, and a low pressure is formed near the ground in Sichuan Basin. High pressure is easily attracted by low pressure. A new low pressure area appears in the Three Gorges area. April-August will attract the Hawaiian high in the Pacific Ocean to move westward, thus preventing the summer monsoon from moving northward. Instead of arriving in the middle and lower reaches of the Yangtze River as usual in June, there will be sunny and dry weather. The rain belt lingers in Guangdong and Guangxi. 165438+ 10, after the temperature drops in October, the low-pressure area in Sichuan will increase its attraction to Siberian high, change some directions, and make the winter snowfall belt move south.
