Abstract:
In 2021, the annual climate anomaly was warmer and wetter in China. The annual mean temperature nationwide was 1.0℃ higher than normal, breaking the historical record since 1951, and the annual precipitation was 6.7% more than normal, ranking the 12th highest since 1951. The seasonal precipitation in spring, summer and autumn was above normal, but below normal in winter. The onsets of pre-flood rainy season in South China, rainy season in Southwest China, and Meiyu season were all later than normal, while the withdrawls of these rainy seasons were earlier than normal with deficient precipitation. However, the rainy season in North China and Northeast China as well as the autumn rain in West China all started earlier and ended later with abundant rainfall. The autumn rainfall in West China was the most since 1961. In 2021, floods were more severe than droughts in China. The torrential rain intensity in rainy season was very strong, featured with significant extremities. The extreme severe torrential rain in Henan Province caused serious life and property losses. Autumn rainfall in northern China was more than normal. The influences of drought, typhoon, hail and hale, frost and snow disaster losses were light.
