There are generally three paths by which air pollution is transported into Maryland. Long-range transport typically originates in the Midwest and travels hundreds of miles on upper air wind currents. Mid-range night-time transport originates south of Maryland and travels tens to hundreds of miles on upper air wind currents. Local transport is characterized by movement between urban areas like Washington to Baltimore to Philadelphia on surface winds.
