Abstract:
By using the precipitation data at 503 stations across China during 1951-2009, the evolution characteristics of drought in China are analyzed on the basis of spatial and temporal precipitation distributions at each season and area. The results indicate that the precipitation in China during each season showed not only a stable interannual change but also an interdecadal variability. The precipitation in autumn has a unified decreasing trend since the 1950s, suggesting that droughts become much frequent in this season. The North China easily has droughts in summer, while autumn droughts prefer the South China since the year 2000. The extremely severe drought in the Southwest China after the year 2000 might have a close relationship with the earlier withdraw date of the Bay of Bengal (BOB) monsoon.
