RESEARCH ON TROPICAL RAINFALL PATTERNS AND ASSOCIATED MESOSCALE SYSTEMS.

Abstract

A study is initiated of some aspects of rainfall in Guyana. The discussion includes the seasonal changes of rainfall and especially the variations of rainfall, along with an analysis of the coefficient of association of rainfall across the area. The work concerning the monthly precipitation changes was extended to tropical South America and has brought to light some of the inherent synoptic patterns associated with the rainfall changes. Work has begun on a study of the maximum 24-hour precipitation amounts, using the statistical theory of extreme value analysis. Preliminary results have been most encouraging. A heavy rain storm which caused flooding in Bogota, Colombia occurred on 17 April 1965. A network of recording raingages make it possible to study cause of development, movement and rainfall intensities over five minute periods. (Author)
