Abstract

Among the natural disasters, floods involve the highesthuman casualties. The economic damages of flood in developing countries, including Iran, is much more, and its occurrence is very high particularly in the cold months of the year in the west of the country. By studying the synoptic maps of the Earth’ s surface and the middle and upper levels of the atmosphere, many Earth-surface phenomena such as flood, based on the spatial arrangement of the pressurecurves or the height and the location of patterns on these maps, the pattern of daily weather conditions can be controlled and the origin of many of these phenomena can eventually be determined. Precipitation is the major climate phenomenon resulting from the complex interactions of the climate system and it has a complex behavior due to the bond with various components of the climate system. The occurrence of precipitation requires the provision of several conditions. The availability of moisture, deep instability and cooling, are the prerequisites for the occurrence of precipitation. All of these conditions must appear in its strongest state for the occurrence of super heavy rainfalls. The western region of Iran is a suitable area for exacerbating and extending rainfall and sometimes flooding due to the presence of mountains. This is because the role of mountains in in capturing air humidity plays a significant role in increasing the atmospheric precipitations. There are two types of approaches in synoptic studies: circulatory to environmental, and environmental to circulatory. In the study of precipitation, the environmental to circulatory classification and approach are used. The reason for thisis that, the temporal and spatial variations of rainfall are severe, and the environmental to circulatory method allows the researchers to concentrate on the precipitation and, consequently, on the synoptic patterns whichtheyintendtostudy. In this study, the heavy and pervasive rainfall in the province of Kermanshah on October 27-30, 2015, was selected and it was attempted to analyze the synoptic and thermodynamic conditions of the occurrence of this torrential rain...
