threshold for which the rainy season beginning merges with its end. This implies a
zero length rainy season. This rainfall threshold represents the maximum daily
rainfall or the maximum ARWS amount with a return period of 1 year. This
threshold was obtained by equalizing the linear regression equations for the
beginning and ending of the rainy season. Table 3 shows these rain thresholds for
various percentiles. At KRAN, for example, the P50 daily rainfall is 72.5 mm,
