Abstract
Hail of the most dangerous natural phenomenon, which every year with the damage to crops is unsustainable cultivation practices. Therefore, the objective of this research is to comprehensively examine the temporal-spatial distribution and synoptic conditions of this destructive phenomenon for the sustainability of agriculture. For this purpose, the statistical data 18, 25 synoptic stations (1992-2009) in the plant growing season (April to September) and a selection of 10 cases of hail and heavy rainfall-data center NCEP / NCAR synoptic maps sea level, 850 and 500 hPa, cold wind, wet wind, omega, volubility and application environment Grads drawn on the job front. In addition of local factors such as topography of the study area, the results showed that hailing systems such as west winds have been effected the highest frequency of South-West, South and center of the study area. Located deep volatile due to extremely cold weather activities have latitude westerly winds North, Mediterranean and Black on the humidity, temperature difference between the surface (due to hot, humid Frarfthay at ground level) and high levels (with front cold) and ground-level air mass could have climbed the highest frequency of hail in the spring rainfall in April is the peak.
