Since October, the precipitation in most of southern China, southwestern Jiangnan, Jianghuai, Huanghuai and other places has been 3 to 80% less than normal, and there have been different degrees of meteorological drought in various places. According to the latest monitoring, light to moderate meteorological drought occurred in western China, southwestern Jiangnan and Huanghuai, and severe meteorological drought occurred in parts of Guangxi, Hunan, Anhui, Jiangsu and Shandong.
In the next ten days, there will be no obvious precipitation in the dry areas such as Guangxi, Hunan and Huanghuai, and the drought will continue, and the forest fire risk weather level will remain high. It is recommended that all localities should strengthen the scientific dispatch and management of water resources, ensure the production and living of the people, and do a good job in winter agricultural production drought and forest fire prevention.
Guangxi, Hunan and other places Huanghuai drought in
Since October (October 1 to November 9), the precipitation in most of South China, southwestern Jiangnan, Jianghuai and Huanghuai is obviously less, and precipitation is 3 to 80% less than normal. Among them, parts of Guangxi and Anhui In the north, northern Jiangsu, southern Shandong, and eastern Henan, there are less than 80%, and precipitation in southern China and Huanghuai continues to be less, resulting in meteorological drought in various places. According to the latest monitoring, light to moderate meteorological drought occurred in western South China, southwestern Jiangnan, Huanghuai and other places, including heavy drought in parts of Guangxi, Hunan, Anhui, Jiangsu and Shandong.
According to the results of soil moisture estimation on November 10, the surface soils in the southwestern part of Guangxi and northern Henan, eastern Shandong and southern China are lacking.
More than half of the counties in Guangxi have experienced moderate to severe meteorological droughts. According to statistics, as of November 8, 88 counties (cities, districts) in Guangxi have different degrees of meteorological drought in 88 counties (cities, districts), including 1 special drought and 21 heavy droughts. There were 36 droughts and 30 droughts. However, due to the large amount of water stored in the previous reservoir, there have been no drinking water difficulties due to drought and agricultural disasters.
The lack of precipitation in Hunan has led to a decrease in incoming water in the Xiangjiang River Basin. Since October this year (October 1 to November 9), the average precipitation in Hunan Province is 80.0 mm, which is 30% less than the normal period (117.7 mm), of which 3 to 80% are in the central and southern parts of Hunan. There are less than 80% in the southwest. The lack of precipitation caused a mild to moderate meteorological drought in southern Hunan, and heavy drought occurred in the southwestern part of Hunan. Due to the lack of precipitation, the water in the Xiangjiang River has decreased and the water level has dropped rapidly, causing cities in Changsha and Xiangtan to use water urgently.
In the next ten days, there will be no obvious rainfall in the dry areas such as Guangxi and Hunan. The drought will continue
It is expected that before the 18th, there will be no rain in meteorological arid areas such as Guangxi, southern Guizhou and southern Hunan. The drought in the dry areas will continue, and the forest fire risk meteorological level will continue to be higher. From the 18th to the 20th, there may be a light rain process in the dry area. It is expected that the rainfall will be less than 10 mm and the drought will not be effectively alleviated.
In addition, it is expected that in the next 10 days, there will be no obvious precipitation weather process and drought development in meteorological arid areas such as southern Shandong, Henan, northern Anhui, and northern Jiangsu.
Concerns and Suggestions
In view of the drought, the drought in the southwestern part of South China, the southwestern part of Jiangnan and Huanghuai will continue or develop in the next 10 days. Recommendation:
The first is to strengthen water resources management. The dry area should strengthen the management and dispatch of existing storage and storage water resources, start the standby water source when necessary, and seize the opportunity to store water during the precipitation to ensure the production and living of the people.
The second is to do a good job in winter agricultural production and drought relief. Water-saving irrigation should be carried out in a timely manner to ensure the normal growth of crops such as autumn and winter vegetables.
The third is to strengthen forest fire prevention work. The forest fire danger meteorological grades in some areas such as Guangxi and Hunan will continue to be high. All localities should strengthen forest area inspections and prohibit wildfires to ensure the safety of forest areas.
