英文摘要 | Precipitation is expected to increase under global warming. However, large discrepancies in precipitation sensitivities to global warming among observations and models have been reported, partly owing to the large natural variability of precipitation, which accounts for over 90% of its total variance in China. Here, the authors first elucidated precipitation sensitivities to the long-term warming trend and interannual-decadal variations of surface air temperature T-a over China based on daily data from approximately 2000 stations from 1961 to 2014. The results show that the number of dry, trace, and light precipitation days has stronger sensitivities to the warming trend than to the Ta interannual-decadal variation, with 14.1%, -35.7%, and -14.6% K-1 versus 2.7%, -7.9%, and -3.1% K-1, respectively. Total precipitation frequency has significant sensitivities to the warming trend ( -18.5% K (1)) and the T-a interannual-decadal variation -3.6% K-1 over China. However, very heavy precipitation frequencies exhibit larger sensitivities to the Ta interannual-decadal variation than to the long-term trend over Northwest and Northeast China and the Tibetan Plateau. A warming trend boosts precipitation intensity, especially for light precipitation (9.8% K-1). Total precipitation intensity increases significantly by 13.1% K-1 in response to the warming trend and by 3.3% K-1 in response to the Ta interannual-decadal variation. Very heavy precipitation intensity also shows significant sensitivity to the interannual-decadal variation of Ta (3.7% K-1), particularly in the cold season (8.0% K-1). Combining precipitation frequency and intensity, total precipitation amount has a negligible sensitivity to the warming trend, and the consequent trend in China is limited. Moderate and heavy precipitation amounts are dominated by their frequencies. |
