OBJECTIVE ANALYSIS OF PRECIPITATION OCCURRENCE AND TYPE

Abstract

An objective technique was developed to analyze precipitation occurrence and type. A weighted averaging method was used, in which the contribution of a station observation to the analysis is a function of its distance from the gridpoint. A square area centered on a gridpoint was searched to locate stations to be used in the analysis. Developmental testing on 49 hr of data from January 1961 and 72 hr from September 1960 over the eastern half of the United States showed that the method correctly specified whether precipitation was occurring for more than 90% of the analysis area.
