Numerical Modeling of Atmospheric Phenomena Causes a Water Logging in Coastal Areas of the Persian Gulf

Implementation of numerical models of atmosphere with high resolution is one of the best tools to investigate the atmosphere at the time of occurrence of extreme phenomena. The present study has conducted to survey a numerical modeling of the atmospheric phenomenon which generated a water logging in Persian Gulf coastal area that occurred on March 19, 2017.

The WRF numerical model (version of 3.8.1) with the ARW dynamic core was used in this research. The WRF model are used to provide a dynamical downscaling and modeling in a selected domain with a central latitude of the 27° and 30 N and longitude 51° and 30׳ E in a 10 Km resolution.

The results showed that atmospheric variables modeling outputs in the study site were nearly equal to observed station data especially in dry temperature and pressure climatic variables. Also, the maps and diagram which is produced by model, indicated that a supercell thunderstorm has occurred which is caused the severe explosions occurring on the sea surface near the coast of Bandar Dayyer and eventually causing four waves and water logging on these coasts.

Based on the results of the model outputs, the main cause of this flood event was the occurrence of a supercell thunderstorms on the Persian Gulf near the coast of Bandar Dayyer.
