The Rainfall Analysis program analyzes monthly rainfall records quickly and effectively. Longterm rainfall characteristics including a three month index are calculated and compared to current rainfall conditions. Monthly rainfall frequencies and three month averages are determined to provide historical "risk" interpretation for future conditions.

Producers using rainfall information should be able to improve many management decisions. This program determines how current conditions deviates from normal rainfall patterns. This information should help foresee potential crisis decisions and help establish important decision criteria for implementation of alternative contingency plans.

The program utilizes a maximum of 100 years of monthly rainfall data. Results are presented as follows: average monthly rainfall, standard deviation of average monthly rainfall, maximum annual rainfall, median annual rainfall, current annual rainfall (to date), three month average rainfall, standard deviation of the three month average rainfall, maximum and minimum of the three month average rainfall, median three month average rainfall, current three month average rainfall (to date), and the current three month average rainfall as a percent of longterm. Results are presented in tables and graphs.

The program is menu driven so that few spreadsheet skills are necessary. A manual with each step from data entry, calculation, printing, etc. is included. Any one interested is interpreting rainfall data will find the program user friendly and invaluable.

The potential user should be aware that he must also have installed Lotus 1-2-3 by Lotus Development Corporation.
