Wet North, Dry South Left One Net Signal in Vegetation
A preprint reports a sharp rise in overlapping rainfall and drought extremes during China's growing season.
Summary
A preprint reports a sharp rise in overlapping rainfall and drought extremes during China's growing season.
Researchers analyzed spatially uneven hydrological extremes in China and report an increase since 2000 of 2.1 events, or 14.52 affected days, per decade during the growing season. In the most recent five years of their analysis, the annual average reached 6.4 events or 42 days. They associate the pattern with more uneven moisture and circulation conditions plus a northward shift in typical precipitation; expanding drought stress outweighed the compensating effects of rainfall on vegetation growth. The study is an observational and attribution preprint, not a forecast for every region or crop.
