A Summary of the Optoma Program's Mesoscale Ocean Prediction Studies in the California Current System.

摘要: Abstract The OPTOMA program sampled the California Current System mainly on continental rise off Northern from March 1982 to November 1986. Maps of surface dynamic height surveys during summer show intense offshore jets and associated eddies in coastal transition zone. current meanders tend be sharper than those winter so that often have smaller horizontal scale. mean, standard deviation range height, maximum speeds are larger winter. In both seasons, structure at 200 db, relative 450 is weak; filaments less prominent this depth regions strongest flow with eddies. An array three moorings, separated by about 100 km, influenced small-scale which may account for lack large-scale coherence between velocity or temperature variations moorings. Some features appear propagate offshore, mooring clearly shows influence onshore/offshore advection. From dynamical model hindcast experiments, as well maps, local instability processes wind stress curl forcing important evolution mesoscale California.
