marine surge

flujo de aire marino hacia tierra; invasión de aire marino

Definition from http://videojibe.com/2007/06/: In the Bay Area this is a rapidly developing S to SW to WSW to flow of fog laden marine air coming up the coast. This will often weaken the peninsula wind. Depending on its direction, it can make for great winds at Sherman Island and San Luis in the AM or PM and at Larkspur or Berkeley or Pt. Isabel. Often the fog will be too deep at Crissy. A marine surge can be triggered by a strong SFO to SBA south to north gradient and/or an upper level trough offshore and/or a summertime Cut-Off low to the north.
