华中地区干旱特征指数数据集（1982-2015）

数据集基于1982-2015年CMFD数据计算的标准化降水实际蒸散指数（SPAEI指数），数据内容包括以下变量：年均干旱历时、年均严重干旱历时，最大干旱历时，最大干旱历时发生时期，年均干旱频率，年均严重干旱频率，年均干旱烈度，年均严重干旱烈度，最大干旱烈度，最大干旱烈度发生时期。数据集空间范围为华中地区，数据保存格式均为TIF，数据集用以描述华中地区在研究期内的干旱特征，可为华中地区干旱特征研究提供参考。

This dataset is developed from the Standardized Precipitation Actual Evapotranspiration Index (SPAEI) calculated using CMFD data spanning from 1982 to 2015. The dataset contains the following variables: annual mean drought duration, annual mean severe drought duration, maximum drought duration, the occurrence period of maximum drought duration, annual mean drought frequency, annual mean severe drought frequency, annual mean drought severity, annual mean severe drought severity, maximum drought severity, and the occurrence period of maximum drought severity. The spatial coverage of this dataset is Central China, and all data are stored in TIF format. This dataset is used to describe the drought characteristics of Central China during the study period, and can provide references for relevant studies on drought characteristics in Central China.
