Abstract

Flood is one of the environmental hazards that creates some damages every year. With due attention that it can explain the most environmental characteristic in relation to circulation patterns, it becomes a necessity to determine and study creation synoptic patterns of spread and destroy floods.In this study, after determining of spread and destroy FLOODS THRESHOLD, the 500 HP level high data analyzed with FACTOR ANALYSIS method and Ward`s method hierarchical clustering using SPSS statistical software for 44 flood(171 days) generating storms during 1370-1384. Finally, seven synoptic patterns generating of spread and destroy floods recognized and classified over URMIA LAKE BASIN.Research results show that the trough axis has been deepened while occurrence of mentioned floods and either URMIA LAKE BASIN position seems related to high level disturbances took place in bottom area of western winds short waves trough high diverg ence or located in bottom-front section of Cut-Off Low system synoptic or occurred in bottom-front part of blocking system western winds southern direction. Among them synoptic pattern of western winds short waves trough generated 67.2 percent of all floods.
