Abstract
Droughts are a recurrent phenomenon and an inevitable part of the existing climate. Over a period of years, precipitation will vary around the average (or normal), so these year-to-year variations can not be ignored when activities depend on optimum levels of rainfall. The impact of below average precipitation can range from inconvenience to serious economic loss. The extent and seriousness of the impact depends on social and economic factors and in part on the intensity, duration, and frequency of precipitation deficit. Historical rainfall records can be analyzed to characterize precipitation deficits -- the average amount of deficit (intensity), the time periods over which they prevail (duration), and the chance that such events will reoccur (frequency).
