Chesapeake bay breeze: Enhancement of air pollution episodes and boundary layer venting

Much like other locations susceptible to sea, bay, or lake breeze circulations, the Chesapeake Bay breeze plays an important role in local air pollution events in Maryland. The transport of emissions from the Baltimore-Washington metropolitan area, favorable O₃ production conditions over the bay waters, and subsequent transport of high O₃ via the bay breeze lead coastal locations, such as Edgewood, MD, to observe some of the worst air pollution in the region. The Chesapeake Bay breeze also lofts pollutants from the surface into the free troposphere at the convergence zone, allowing pollution to be transported farther down-wind from source locations.
