The model includes nonlinear convective accelerations, lateral mixing and bottom friction; wave refraction is specified using a semi-discrete Galerkin method. The model is applied to predict realistic meandering currents occurring on a periodic rip channel. Due to the nonlinear inertial effect, the unaccelerated longshore current profile is stretched and causes a decrease in the magnitude of maximum velocity. Comparison with the linear analytic solution suggests that the latter significantly overestimates maximum velocity. The numerical results quantitatively demonstrate the relative importance of the nonlinear convective terms in the nearshore current problem. Dept. of Oceanogr., Naval Postgrad.

Labrador Sea are less saline than they were during the 1960s. The Western Boundary Undercurrent is stronger than geostrophic estimates based on the traditional 1500 dbar reference level would indicate. Transport estimates are within the generally accepted ranges for the East Greenland Current, North Atlantic Current, Labrador Sea Water, and Western Boundary Undercurrent. An estimate for the transport of the Irminger Current, higher than traditional estimates, can be reconciled with the outflow of Labrador Sea Water and the offshore Labrador Current.

The main contribution of dense water to the western North Atlantic flows through Denmark Strait. The time-averaged volume flux of water colder than 2°C is 2.9 × 106 m 3 s-I. The temperature-salinity characteristics of this 'overflow' water are dominated by Arctic Intermediate Water and Norwegian Sea Deep Water.

On vertical motion, divergence, and the thermal wind balance in cold-dome meanders: a diagnostic study. J. geophys. Res., 90(C2):3173-3183. Wavelike meanders are observed along the length of the Florida Current from the Florida Keys to Cape Hatteras; each has a cold dome and a meandering flow that overtakes the dome in a cyclonic turn. The pattern of vertical motion is one of upwelling formed by the forepart of the translating dome and its overlying onshore flow and a downwelling that similarly extends vertically through the rear part of the dome and its overlying offshore flow. The vertical motion and the translation of the meander are interrelated; both influence acceleration of the water columns and skewness in the strength of the meandering flow component. As the thermal wind changes with the divergence accompanying the vertical motion, it also provides a twisting mechanism to help restore the thermal wind balance. NOAA, AOML, Miami, FL, USA.
