The rainy belt has shifted westward and expanded northward, and in recent years, both the frequency and intensity of heavy rain in the northern region have increased.

From the flood season safety knowledge release conference held today by the Ministry of Emergency Management, it was learned that in recent years, extreme weather events that break traditional patterns and go beyond conventional understanding have significantly increased. The rainy belt has shifted westward and expanded northward. Compared to the 1990s, the area of China's humid and semi-humid climate zones has expanded by more than 300,000 square kilometers in the past five years. In particular, the frequency of heavy rain events in northern China has been about 50% higher in the past five years than in the 1990s, and the overall intensity of heavy rain events during the same period has been about 50% stronger. Flood prevention in northern China has shifted from the previous "prepare more, fight less" to the current "regular severe test". It is expected that in the next five years, the overall characteristics of heavy rainfall in northern China will continue, with a higher probability of above-average precipitation in Northeast China and most parts of North China, increasing the risks of flooding and severe convective disasters. In response to the new challenges brought by the northward shift of the rainy belt and the new situations faced by flood prevention work in northern China, the Ministry of Emergency Management, together with the Organization Department of the CPC Central Committee and the Central Party School, organized special training to improve the flood prevention, reduction, and relief capabilities of grassroots cadres in northern China. More than 300,000 city and county party and government leaders, as well as village party secretaries, from 16 provinces participated. This aims to accelerate the construction of flood control projects, urban drainage systems, meteorological monitoring, emergency rescue, and other capabilities in relevant departments and regions, thereby enhancing the flood prevention, reduction, and relief capabilities in northern China.
