SOME THREE-DIMENSIONAL CHARACTERISTICS OF LOW-FREQUENCY CURRENT FLUCTUATIONS NEAR THE OREGON COAST.

Abstract

AN ANALYSIS IS PRESENTED OF THE LOW-FREQUENCY FLUCTUATIONS (W%0.6 CYCLE PER DAY %CPD < AND NORTHWARD %APPROXIMATELY ALONGSHORE< COMPONENTS OF THE CURRENTS.THE MEAN ALONGSHORE VELOCITY O HAS THE STRUCTURE OF A BAROCLINIC COASTAL JET, WHOSE MAXIMUM SPEED OCCURS NEAR THE SURFACE AT A DISTANCE OF ABOUT 15-20 KM FROM THE SHORE, WHEREAS THE FLUCTUATING PART OF V HAS THE STRUCTURE OF A ROUGHLY BAROTROPIC COASTAL JET WHOSE MAXIMUM OCCURS VERY NEAR %%4KM <
