Abstract:
The general feature of China’s climate in 2020 is warm and wet. The 2020 annual mean temperature over China was 0.7℃ higher than normal, becoming the eighth warmest since 1951. The temperatures in all the four seasons were above normal, and much warmer in spring and winter. The annual mean precipitation over amount China was 694.8 mm with 10.3% more than normal. The seasonal precipitation in spring was below normal, but above normal in summer, autumn and winter. The pre-flood season in South China started and ended both earlier than normal with deficient precipitation. The rainy season in Southwest China started later but ended earlier than normal with more heavy precipitation. The Meiyu season started earlier but ended later than normal with more precipitation, resulting in the longest rainy period and the most precipitation amount since 1961. The rainy season in North China, the autumn rain in West China and the rainy season in Northeast China started and ended later than normal with more rainfall. In 2020, the landing typhoons were fewer than normal, feathering concentrated landing locations and periods of time, with lighter disaster losses. Rainstorm and floods occurred heavily, causing serious losses in China. The impacts of other disasters such as droughts, severe convection, cold freezing and snow disaster as well as sand-dust storms, were all mild relatively.
