| 摘 要： | 从干旱实时监测气象服务的需要出发，研究并提出了考虑近期降水、土壤底墒（前期降水）和气温三种要素，利用实时天气资料来计算干旱指数的方案，即重庆市干旱动态监测指数。该指数考虑了造成干旱的三个主要原因：降水持续偏少、日最高气温高、前期降水少。利用该指数，建立干旱实时监测业务系统，对2004年重庆市盛夏发生的干旱进行了逐日跟踪动态监测，效果良好。

| Abstract: | Based on the requirement of the meteorological service of real-time monitoring drought,a calculation scheme of drought index, the drought index of the dynamic monitoring in Chongqing, is designed in consideration of three conditions including precipitation in recent time,soil moisture(preceding precipitation)and air temperature, with real-time weather informance. The index is based on the main three factors resulting the drought, which is continuous less of rainfall, higher daily maximum temperature, and less rainfall in the prior period. The operating system of the real-time drought monitoring was established based on the index, and it did well in the daily dynamic monitoring of the drought in Chongqing in the midsummer of 2004. |
