Almost half the U.S. population lives along the coast. In another 20 years this population is expected to more than double in size. The unique weather and climate of the coastal zone, circulating pollutants, altering storms, changing temperature, and moving coastal currents affect air pollution and disaster preparedness, ocean pollution, and safeguarding near-shore ecosystems. Activities in commerce, industry, transportation, freshwater supply, safety, recreation, and national defense also are affected.The research community engaged in studies of coastal meteorology in recent years has made significant advancements in describing and prediciting atmospheric properties along coasts.Coastal Meteorologyreviews this progess and recommends research that would increase the value and application of what is known today.
