The Gulf Stream and Its Frontal Structure: A Quantitative Representation

摘要: Abstract The structure of the Gulf Stream Current is associated with quasi-permanent density front in western North Atlantic. lighter mass warmer but saltier water Sargasso Sea separated from slope by inclined isopycnals that form front. Recent satellite altimeter measurements have also revealed a well-defined sea-surface height change across In this paper, model cross-sectional and current presented, using complete dynamical mass-conservation equations. postulates forcing, at interior ocean boundary, cross-stream ageostrophic circulation inflow light upper return flow greater depths. found to develop after initial geostrophic adjustment several inertial periods. quasi-steady state, normalized structural results constitute single representation all sections; i.e., sections ar...
