Abstract : The varibility of rainfall in Guyana is discussed and demonstrated by use of the Contingency Index. The changes are shown as both areal and seasonal. The size of cells in relationship to the season is demonstrated. The concept that a preceding month can be used as a predictor for a succeeding month is investigated for some stations in Guyana. Scatter diagrams and correlation coefficients indicate that an inaccurate forecast would probably result. The ojive of cumulative frequency vs. cumulative amounts of daily rainfall is used to compare the rainfall in Cambodia with rainfall in Central America. Most of the Cambodian rainfall ojives are similar to the Central American curves. A study of the hourly rainfall for several stations in Cambodia provides a mean rainstorm for the area. The duration and hourly amounts are also noted. A contingency method study for three stations with long periods of records in SEA has elicited the information that a few relationships between rainfall in one month and the amount in a succeeding month have highly significant correlation. These cases are to be studies in more detail. (Author)
