AB: An observational and modeling study was performed over the Arabian Gulf region to investigate the coastal circulations and aerosol transport in the area. Climatological data and observations from the United Arab Emirates' Unified Aerosol Experiment were used to develop a better understanding of the complex meteorological processes in the Arabian Gulf region. Climatological data suggests that sea breezes occur on more than 77 percent of days in all months of the year and land breezes occur on more than 70 percent of the days. The occurrence of the sea and land breeze circulations are higher (90-99 percent) during the summer months when large-scale weather patterns are quiescent. Measurements of aerosol concentrations taken during the Unified Aerosol Experiment(2004) experiment are used to investigate aerosols, namely dust, transported in the Arabian Gulf region. Vertical profiles of dust concentration along with vertical profiles of potential temperature and wind are used to determine the source region, transport distance, and height of the dust layer. The aircraft aerosol vertical profiles suggest highest dust concentrations occur near the surface. Numerical simulations of two periods during the summer of 2004 were performed to test the ability of COAMPS (Coupled Ocean Atmosphere Mesoscale Prediction System) to resolve the sea breeze circulation and to understand the horizontal and vertical structure of the sea breeze. Results from these simulations will be presented.
