The China Meteorological Administration has launched a Level 4 drought emergency response. Why is this year’s drought so severe?

The leaders of the China Meteorological Administration issued the order, the Office of the China Meteorological Administration, the Emergency Disaster Reduction and Public Service Department, the Forecasting and Network Department, the Comprehensive Observation Department, the National Meteorological Center, the National Meteorological Administration, the National Climate Center, The National Satellite Meteorological Center, the National Meteorological Information Center, the Earth System Numerical Prediction Center of the China Meteorological Administration, the Meteorological Observation Center, the Public Meteorological Service Center, the Artificial Weather Modification Center, the Meteorological Publicity and Science Popularization Center, and Huafeng Group will immediately enter the fourth level of drought. emergency response. Meteorological bureaus in Jiangsu, Anhui, Henan, Hubei, Zhejiang, Fujian, Jiangxi, Hunan, Guizhou, Chongqing, Sichuan and other provinces have initiated or adjusted emergency responses at corresponding levels based on actual research and judgment.

Increase personnel on duty, strengthen duty, mobilize and deploy flood control and drought relief work; dispatch water conservancy and flood control projects according to authority; transfer personnel in dangerous areas as planned, organize and strengthen embankment inspections and defenses, control dangerous situations in a timely manner, or organize and strengthen drought relief Work. The heads of flood control and drought relief command agencies at all levels and the heads of member units in disaster areas shall organize and guide flood prevention and drought relief work in their respective jurisdictions according to their responsibilities, or be stationed in disaster-stricken areas. Specially help the hardest-hit areas with flood prevention and drought relief. The flood control and drought relief command agencies of each province, autonomous region, and municipality directly under the Central Government will report their work status to the local people's government and the General Administration of National Defense.

A once-in-a-century heatwave is sweeping across Europe, with temperatures exceeding 40?C in many places. The highest temperature in Paris, France reached 40.5°C; the temperature in some areas of Portugal and Spain once reached 47°C; the temperature in many places in the UK exceeded historical extremes. The highest temperature in Corningsby, Lincolnshire, UK reached 40.3°C, the highest ever recorded in the UK. The UK has declared a state of emergency and issued its first-ever red alert for extreme heat. Europe's heatwave killed more than 1,700 people in Portugal and Spain alone, the World Health Organization said. The subtropical high pressure in the Northern Hemisphere is extremely strong and almost orbits the Earth, with only a significant break near India. Northern South America and southern Central Africa are also controlled by the Southern Hemisphere subtropical high. In Europe, the subtropical high pressure and the continental high pressure overlap in phase. Affected by factors such as atmospheric clear-sky radiation, subsidence warming, and warm advection transport, large-scale sustained high temperature weather occurs.
