They are called the local rainfalls in special regions, either in spring when it becomes hot, or in autumn before it becomes cold. The unexpected rainfalls that happened in May in 2007, were exceptional because it rained heavily for along time. This event is caused by many atmospheric factors and local reasons. The results were great floods and inundation which caused losses in properties and souls and that led to soil Erosion.
