Abstract
In theflood19July 2015, short-duration convective rainfall leads to flashflood inan area of about300km2arefallingin the short termanddue tointenserainfallin a short time, being a small basin area ,low concentration time andman-madefactorsdestructiveterriblefloodoccurred. In this paper, using WRF modelandweather patterns, thedevastating floods, from themeteorologicalperspectiveis studied.The results of the simulated instability indicators, consider to be suitable for the structure of the atmosphere and the lack of preventive factors of convection has been to create a severe instability and rainfall amounts resulting from the model outputsat the time of the occurrence floodis also well simulated by the model. Large-scale atmospheric patterns of 19 July, the existence of the thermal low pressure center on the South and southeast and the gradual expansion of the thermal low pressure to the central areas of the country and the establishment of the high pressure plumes on the Caspian coast with intense pressure gradient on the central Alborz that shows withthe levelstroughof themiddle and upperatmosphere associated andfavorable conditions for theoccurrence ofextreme precipitationhas provided.
