Research on Tropical Rainfall Patterns and Associated Mesoscale Systems.
Abstract
The onset and ending of the rainy seasons along the northeast coast of South America is determined by using five day totals of rainfall. During both the rainy and dry seasons, surges of rainfall occur which can be identified and in some cases the movement of the surges can be tracked. Maps of the monthly and annual mean and standard deviation have been drawn for the Southeast Asian Peninsul a using data for 87 long-period stations. These maps are described and analyzed with regard to amount and variation. A study was made of reported rainfall as a function of the density of gages for several geographical areas including Texas, Colombia, Guyana, Panama, Venezuela, and Ecuador--each having different terrain Consideration was given to the data required to determine daily or long-term monthly means. Daily data for 124 stations in Central America are studied to determing rainfall patterns for the area. Data were grouped into 5-day or pentad rainfall totals and means and frequency of occurrence of selected amounts were determined for each pentad at 61 stations. (Author)
