| Abstract: | The concept of the relative moisture index was introduced on the basis of meteorological observation data which observed since the 1970s, defining M≤-0.40 as the standard of meteorological drought. The changing trend of relative moisture index and meteorological drought characteristics of crop growing season each month were analyzed in recently 39 years, and researching the reasons for these trends deeper which provided a reference for fighting the local agricultural drought. |
