Zusammenfassung:Rainfall is frequently used as a climate index during prolonged dry seasons and extreme rainfall to determine changes in global climate. This study estimates average total rainfall for the study area based on arithmetic mean and the Thiessen polygon methods. The objective was to analyze rainfall variability based on statistical analysis of variance and to produce maps of rainfall variability using isohyetal contour techniques. Based on the two methods, results showed three distinctive rainfall patterns occurred for consecutive years within the study area.
