Two case studies have been investigated using high-resolution WRF model simulations. The purpose of these case studies is to determine the effects of wind patterns on visibility and aerosol transport in the region. In the first case study, strong synoptic-scale forcing led to a large-scale pressure gradient resulting in strong wind and longrange aerosol transport. In the second case study, the mesoscale land/sea breeze offset weak synoptic-scale forcing near the coast. The daytime sea breeze and nighttime land breeze limited the ventilation of air masses and allowed recirculation of contaminants and aerosols near the shoreline, which may strongly influence visibility and air quality locally.
