Title

A SYNOPTIC ANALYSIS ON FLOOD-MAKER THUNDERSTORMS IN KERMANSHAH PROVINCE

Pages

  21-41

Abstract

 Many social and economic activities of human beings depend on weather conditions and climate. One of the phenomena affecting the production of runoff and flood events in most latitudes is occurrence of thunderstorms in the local-regional scales. Due to the occurrence of severe thunderstorms with heavy rainfall, a lot of losses in the province are created in Kermanshah. So, understanding the mechanism of formation and development of storms can help to reduce the frequency of losses and increase agricultural production and productivity levels … in this province.In the present study, in an eight-year statistical period (1987-1994) data of thunderstorms (which includes the 95-99 codes) was taken for the KERMANSHAH PROVINCE from Iran's Meteorological Organization and the data of synoptic pressure, and especially not in the Omega Sea level pressure, 850 and 500 hpa were received from Forecast Center of the so-called environmental NCEP and maps needed were drawn in the software environment of GRADS. By extracting rainfall statistics these storms and matching them with data, the four flood discharge were identified during the statistical period.Overall, the floods created three (25 and 26 October 1987 and November 7, 1994) will follow a template pattern so that the tabs in the sea level pressure of dry and cold air flow under study area and in higher balances system, hot and humid air pressure to the Arabian Sea under study area located in front of trough in the West Country will flow. In December 24, 1987, large low pressure system covered Western Asia, would cover the Western part of country and in higher balance of the study area, quite deep trough in the western front is located. Also, in a review of humid maps, it revealed that the most moisture advection in above-mentioned flood basin was through the Arabian Sea.
