According to the provincial meteorological department, drought has developed rapidly in the province since mid August due to low temperature, high rainfall and so on. As of October 29, 45 cities and counties in the south of the Huaihe River had maintained severe meteorological drought, most of them along the river were extremely dry, most of which occurred once in 30-50 years.

Xiaowangs hometown is in Tongcheng, Anqing, which is just beside the Yangtze River. He told the Beijing news that at the beginning of this month, when he came back to his hometown during the national day, he found that the pond near his home had completely dried up. When I was a child, my home was near the pond. The water in the pond has been abundant. When I grow up, I can occasionally go back and see some children fighting beside it. I havent seen the dried pond for so many years.

Cheng Zhi, senior engineer of the climate center of Anhui Province, analyzed that the East Asia geopotential height field is in a horizontal configuration of high in the West and low in the East, which is not conducive to the transportation of southwest air to the north, resulting in the weak water vapor transportation in a large range of areas in the middle and lower reaches of the Yangtze River, so the precipitation in Anhui Province will be abnormally less, while the cold air in the north is weak, and the temperature is significantly high, which also leads to the increasing drought.

It is reported that the Department of water resources of Anhui Province has recently launched a level IV emergency response for drought prevention, requiring water conservancy (water affairs) bureaus in cities south of the Huaihe River to formulate water supply guarantee schemes at all levels, to ensure the safety of drinking water for rural people, and to guarantee urban water supply, large-scale breeding livestock and poultry drinking water and autumn planting water sources.

At the same time, Yuan Ye, director of the Weather Modification Office of Anhui Province, also introduced that Anhui Province will seize all favorable opportunities to actively organize and carry out the three-dimensional artificial precipitation enhancement operation of aircraft and ground. Since October, the province has carried out 7 aircraft rain enhancement operations, with a total flight time of 21 hours and 32 minutes and 112 cigarette sticks burned; organized 15 cities such as Hefei and Jiuhuashan scenic spot to carry out ground rain enhancement operations for 212 times, launching 327 rockets and 180 cigarette sticks burned. Under the combined effect of natural precipitation and artificial precipitation, the drought in the north of Huaibei has been alleviated to some extent, but the drought in other areas is still continuing.

According to reports, Anhui Meteorological Bureau has urgently adjusted enough rockets and cigarette sticks, and prepared enough ammunition. Three rain increasing aircraft are on standby. Once favorable weather conditions are found, rain increasing operations will be organized immediately.
