Abstract

In this study, in order to estimate the amount, for special and temporal patterns of precipitation over Iran, a simple model of precipitation forecast was used with two parameters namely VERTICAL MOTION and PRECIPITABLE WATER. The VERTICAL MOTION and PRECIPITABLE WATER were computed in different methods as follows:The Kinetics with the correction of divergence and quasi-geostrophic omega equation were applied to estimate the VERTICAL MOTION. Then the temperature dew point and the vertical integration of specific humidity trom surface up to 100 HPa were used to estimate PRECIPITABLE WATER.There were two cases of investigation which have been done from 10 to 12 January 2002 and 26 to 28 December2004whichshowedthat usingthe Kinetics methods with the correction of divergence and vertical integration of specific humidity have given best results in estimating the two parameters.And finally comparing the results of precipitation of the model with actual precipitation, showed that in spite of over estimating the amount of precipitation for spatial and temporal patterns, there was no difference between the model and the real precipilation.
