Conference paper

Abstract

The term drought has never been given a quantitative definition acceptable to everyone. In loose terms it is an extended period characterized by lack of precipitation, the consequence of which is generally reflected in some important phase of the changing economy. Under this definition dry spells in areas at times when little or no rain normally falls are not considered drought periods, and the anomalous character of precipitation is an important part of the definition. It is this phase of the subject which shall be discussed in this article with particular emphasis on the departures of precipitation from long-term normals (the climatic anomalies of precipitation) as they relate to the atmosphere’s broad-scale or general circulation.
