Modeling Spatial Distribution of Thunderstorm Rainfalls Mountainous Areas of the Northwest of Iran

Thunderstorm rainfall is one of the most important climatic phenomena in the northwest of Iran that has specific variability in spatial distribution. These rains have an important role in case study area climates. The purpose of this study is investigation of spatial distribution of Thunderstorm rainfall of Mountainous Areas of the Northwest of Iran to modeling Thunderstorm in northwest. Because of that TRMM images precipitation data from 2009 to 2012 is selected & in the software Arc Gis، ENVI and EDRISI، have been processed.
