Spatial Distribution Modeling of Lightning Precipitation Using Satellite Images and Estimation of Perceptible Water, Case Study:Cities of Ardebil Province

Thunderstorms rainfalls are a kind of unstable storms that are caused by an extremely strong abnormal state of atmospheric displacement and are one of the most important climatic phenomena in the northwest of the country.The aim of this study was to determine the spatial distribution of thunderstorms rainfalls in Ardabil province by using satellite images and Estimation of perceptible water. In this study, synoptic stations data, satellite imagery and MODIS bands 17 and 18 for Estimation of perceptible water were used. Images of thunderstorms rainfalls on 05.10.2010 and 18.06.2012 in ENVI4.4 software was processed and then they were interpolated in ArcGIS. Also, the results of interpolated field data revealed that the highest thunderstorms rainfalls are at Khalkhal station and lowest occurs in Meshkinshar station. In addition, thunderstorms rainfalls in the province in the spring and early summer lightning occurs. The results of the analysis of ground data and satellite imagery indicated this fact that the thunderstorms rainfalls derived from satellite imagery is far more accurate than data that obtained from the harvest of the earth. Also, maps of thunderstorms rainfalls can be extracted quickly and accurately, as well as using in the prediction of atmospheric hazards and optimal water resources planning in Ardabil province.
