The Research of the Regional Meteorological Drought Assessment Model

Abstract:

The drought turns more serious in recent years, and it lacked an appropriate system to assess the regional meteorological drought. The paper took Weihe basin for example, completed the regional meteorological drought assessment by four steps. They were the drought evaluation units division, the drought index selection and calculation based on RDI (reconnaissance drought index), the drought identification and the drought characteristic values analysis based on the correlation coefficient and the copulas connect joint distribution function analysis. It discussed the interrelationship of the regional drought characteristics of area, duration, severity and frequency, and formed a relatively complete regional meteorological drought assessment system.
