ALT The Marine Layer: Cool, moist air trapped near the surface by a temperature inversion aloft. Can result in low clouds and fog near the coast. - Persistent high pressure anchors over the eastern Pacific - Warm air aloft sits over the cool air trapped near the surface, resulting in a temperature inversion - Cold water flows down the coast, helping to cool air near the surface - The strength of the inversion determines how far inland low clouds extend = Deep marine layer = cloud farther inland = Shallow marine layer = clouds confined to coast
ALT The 5 PM satellite image showed marine layer clouds surging inland (again), and dissipating storms over the mountains and deserts.
