It was verified that in April, natural disasters throughout the country were dominated by meteorology and flood and drought disasters. The northern region suffered many low-temperature freezing and snow disasters, and the southern region was dominated by wind and hail, floods and droughts, and local disasters were severely affected. Various natural disasters caused 8.148 million disasters, 5 deaths, and more than 10,000 emergency resettlement; more than 300 houses collapsed and 38,000 houses were damaged; the area of crops affected was 12.98 million hectares, of which 11.192 thousand hectares were received; direct economy The loss was 10.21 billion yuan.

The country suffered three cold air processes, and the northern region suffered heavy losses from low-temperature freezing and snow disasters
From April 19 to 22, the cold air process affected Inner Mongolia, Northeast China, North China, Jianghuai, Jianghan and other places. In some areas, the temperature dropped by 8-12 ° C, and the local temperature dropped to blizzard. The 61 counties (cities, districts) of 11 cities such as Jinzhong and Changzhi in Shanxi are at a time when the output of flowering forests and some cash crops has been cut, resulting in a direct economic loss of 1.77 billion yuan. The lowest temperature in Shandong Weifang and other places dropped to -5.1 ℃, which caused freezing damage to the forest fruit and wheat at the booting stage, with a direct economic loss of 1.09 billion yuan. Blizzards in Qiqihar, Heilongjiang and Heihe 2 cities led to the loss of more than 30,000 agricultural greenhouses and a direct economic loss of 300 million yuan. In addition, the direct economic losses caused by low temperature freezing and snow disasters in Shaanxi, Ningxia, Hebei, Gansu and other provinces (regions) exceeded 500 million yuan. Compared with the average of the same period in the past five years, the national low temperature freezing and snow disasters in April were significantly more important.
Southwest China is heavily affected by strong convective weather, and hail disasters occur intensively
In April, there were five severe convective weather processes across the country. From April 13th to 14th, a wide range of strong convective weather occurred in southern Sichuan, resulting in an area of 5.8 thousand hectares affected by forests and crops in 6 counties (districts) of 2 cities (prefectures) in Panzhihua and Liangshan, with a direct economic loss of 100 million yuan. From 17th to 19th, strong convective weather such as strong winds, hail and short-term heavy rainfall occurred in many places in Guizhou, causing a direct economic loss of 450 million yuan. On 21-22, strong convective weather such as thunderstorms, strong winds, and hail occurred in southeastern Yunnan, causing damage to crops and agricultural facilities and direct economic losses of 500 million yuan.

Yunnan's drought partially eased and forest fire situation improved somewhat
Affected by factors such as low total precipitation in the early stage and uneven spatial and temporal distribution, this year, Yunnan Province has had fewer river water inflows and less reservoir storage. As of mid-April, there were 137 river outages in the province, and 201 reservoirs have dried up. Water storage was the least since 2015, with 2.433 million people affected in 81 counties (cities and districts) in 16 cities (prefectures) such as Yuxi, Pu'er, and Zhaotong. 662,000 people needed help for drought. The area affected by crops was 5.34 million hectares The direct economic loss was 1.41 billion yuan; since late April, Yunnan has experienced continuous rainfall and drought conditions have been alleviated in some areas. Since April, the northwest and southeast of the northwest region have had less precipitation and higher temperatures, and local meteorological arid outcrops have developed. According to preliminary statistics, in April, there were 159 forest fires across the country and three people died. Compared with the previous month and the same period in recent years, the number of fires decreased significantly, and the situation of forest fires has improved.
