Planetary and Topographic Beta Effects on the Northern Canary Current System (NCCS)

摘要: Abstract : To investigate planetary and topographic beta effects on classical as well unique features in the northern Canary Current system (NCCS), several numerical experiments using Princeton Ocean Model are explored isolate dependence of Coriolis parameterization (beta-plane vs, f-plane) from effect, first (last) two use a flat bottom (topography), In all experiments, eastern boundary condition (EBC) produced including an offshore surface equatorward meandering jet, coastal subsurface poleward currents, upwelling, meanders, eddies filaments, Due to jet does not have be confined within Rossby radius deformation coast, The effect also plays important role development westward propagation Meddies, feature NCCS, Bottom topography is shown play narrowing, intensifying, trapping These results show that, while wind forcing primary mechanism for generating EEC features, roles generation, evolution, maintenance
