Abstract

 Presently, in some countries of the world like Iran, where quantitative and qualitative limitation of water resources, is one of the main obstacles in access to sustainable development programs goals, PEPs through cloud seeding are preformed in order to reduce and resolve the environmental problems. Although the main part of the site-selection studies which are the scientific base for PEPs is climatology of clouds and precipitation, winds and upper air currents in each type of weather have special characteristics in standard levels of the atmosphere, and in each synoptic and thermodynamic atmospheric conditions they are the important indicator of air situation such as stability, instability, and so on. So climatological study of these parameters can provide necessary information for PEPs planners. In this research using the Isfahan synoptic and upper air stations and through drawing the wind roses, we have firstly studied wind speed and direction in atmospheric standard levels (500, 700 Hpa and surface), and then the monthly distribution of mean percent occurrence of above winds in 16 different directions. Finally, through classifying winds into two groups, light and fast winds, we have studied their speed. As a result, we have shown that in the rainy periods the winds and upper air currents can bring the necessary humidity and energy for seedable cloud formation and precipitation occurence in the above mentioned basin.
