CONVERSION ALGORITHM OF RAIN-RATE STATISTICS AND ITS APPLICATIONS FOR VARIOUS INTEGRATION TIME DATA

摘要

A conversion algorithm of the rainfall intensity distribution according to the accumulated time data is provided to effectively estimate domestic one minute accumulation rainfall intensity distribution by converting data measured for a long time more than one minute into the one minute accumulation rainfall intensity distribution. Rainfall intensity data which is measured by a specified few minutes unit is read out from a database(101). A first coefficient of correlation and a second coefficient of correlation which correspond to the specified few minutes unit are obtained to convert the rainfall intensity data into one minute accumulation rainfall intensity data(102). The measured rainfall intensity data are converted into the one minute rainfall intensity data by squaring the first coefficient correlation in the measured rainfall intensity data and multiplying the result by the second coefficient correlation(103).
