Abstract

The available data consists of daily rainfall for the past 24 years (1948-1972) for Lexington, Louisville and Paducah. However, for Ashland, the data is available for the period of 40 years (1932-1972). The problem is to find an appropriate family of distributions indexed by a suitable number of parameters that fits the maximum daily rainfall. Further, there might be seasonal variations. The following seasons were considered: (i) Dry Convective season: August 1-0ctober 30; (ii) Early Convective season: May 1-July 31; (iii) Late Convective season: November 1- April 30. After extracting the yearly maximums for each of these seasons (see Appendix 1), we set about fitting three distributions for each station; one for each season.
