Abstract:
Climate in China was at a normal level in 2018 when fewer climate disasters occurred, relatively. Annual mean temperature (10.09℃) over China was 0.54℃ higher than normal. The temperature in spring and summer reached a record high, while the temperatures in autumn and winter were close to the normal. The annual mean precipitation over China was 673.8 mm with 7.0% more than normal. The seasonal precipitation was below normal in winter, near normal in spring, but above normal in summer and autumn respectively. The first rainy season in South China started later and ended earlier than normal with deficient precipitation. The dates of beginning and end of the rainy season in Southwest China were close to the climatological dates with more heavy precipitation. Meiyu season started later and ended earlier than normal with less precipitation during the rainy period. The rainy season in North China started earlier and ended earlier than normal with more rainfall. The autumn rain in West China started and ended late, with less rainfall. The dates of start and end of the rainy season in Northeast China were near the normal time with less rainfall during the rainy period. In 2018, the generated and landed typhoons were more than normal, featuring northward landing locations and severe disaster damage. Lowtemperature freezing and snow disasters occurred frequently, causing heavy losses in China. Comparatively, 〖JP2〗the effects of other disas〖JP〗ters such as torrential rains, floods, drought, severe convection, and dust were light.
