Variability of precipitation is analyzed in detail for records of 40 to 50 years or more. The probability of occurrence of wet or dry days is calculated for various thresholds of rainfall. Using the Freyerherm-Bark model, tables of initial and transitional probabilities and confidence limits are calculated. Tables of sequences of wet and dry days are also calculated. Computer programs and example problems are presented. Monthly total precipitation is calculated by station and tables and maps are given for the monthly means and of variance about the means. Long-term variations in precipitation were found in analyzing 40-year data series. Variations due to tropical storms are also analyzed. Conclusive evidence is presented that long-term variations do occur and affect nearby locations quite differently.
