英文摘要 | Climate warming generally is expected to increase drought, but arguments about China's past drought trends persist. PDSIARTS, a revised self-calibrating Palmer Drought Severity Index, was computed for China over 1982-2016 using satellite leaf-area indices combined with monthly climate data interpolated from 2000 high-density stations. Drought climatology was analysed against climate factors. The results show that temperature has increased at a rate of 0.38 degrees C per decade (p < .001) in China in the past 35 years (1982-2016). However, over the same interval, China and the northern China region became wetter. PDSI(ARTS)increased at a rate of 0.03 yr(-1)(p < .001) across China during 1982-2016. The analogous increase of PDSI(ARTS)in northern China was 0.05 yr(-1)(p < .001). In China, the 5-year interval from 2012 to 2016 was the wettest 5 years in the 35-year interval. This arises from the coupled effects of decreased potential evaporation (E-p) and increased precipitation (P-r). The implication is that temperature increase does not necessarily indicate increased drought. A potential complication is that the 2015/16 El Nino event induced the highestP(r)in southern China for 1982-2016, and northern China still had plentifulP(r)in 2015/16, which further contributed to the wettest 2-years (2015/16) during the past 35 years in the whole of China. This study highlights the joint impacts ofP(r)andE(p)on the dry/wet changes and the possibility of extremely wet events in the warming future. |
