基于TRMM降水数据的云南干旱分析
Analysis on Drought in Yunnan Based on TRMM Precipitation Data
摘要
Abstract
Based on the TRMM3B43 precipitation data from 2008 to 2012, TRMM precipitation anomaly and accumulated precipitation anom-aly was calculated to study temporal and spatial distribution characteristics of drought in Yunnan Province in different time scale.The results showed that, precipitation was the main factor affecting drought in Yunnan Province, drought mainly occurred in Feb., Jan., Nov.and Dec., the special drought mainly occurred in Nov.and Dec., the heavy drought mainly occurred in Nov., Feb., Dec.and Jan., the moderate drought mainly occurred in Dec.and Feb., the light drought mainly occurred in Feb., in the drought prone months, the drought mainly hap-pend in central area of Yunnan and southwestern Yunnan;From the cumulative drought in Yunnan Province, the drought mainly occurred from Oct.to Jan.Of next year and mainly happend in central area of Yunnan;TRMM data can be used for medium and long-term drought monito-ring.TRMM data are more suitable than measured data in wide-range drought monitoring.关键词
