Derivation of Regression Coefficients and Conversion Factors for 1-Minute Rain Rate Statistics in A Tropical Environment

An important characteristic of rainfall levels at a particular place is the statistical distribution rate. In this paper, 1-minute, 5-minute and 30-minute integration time data were obtained from three different weather stations in Physics Department, Federal University Technology, Minna, North Central Nigeria. The aim to derive regression coefficients conversion factors for predicting rate 1-minute rates other times. This was achieved by employing Segal, Flavin Watson rain models. results revealed that there power law relationship between 1-minuterain (R1) equiprobable (R5); (R30). Also,it observed values b, Ce CR derived Minna locations outside Nigeria when comparisons made. These discrepancies are attributed differences climatic conditions regions among factors. Therefore, these findings have further corroborated claims earlier researchers needed conversion.
