boundary was adjusted to conserve the total volume of the model domain, and the gradient of depth-averaged normal flow with respect to depth was preserved. In this study, the ambient current is assumed to be steady. The model applies bulk formulas ( Fairall et al. 2003 ) using marine boundary layer winds, temperature, humidity, and pressure from the North America Regional Reanalysis (NARR; Mesinger et al. 2006 ), and ROMS sea surface temperature and current to compute air–sea fluxes of momentum and

of the jet shifts north and affects the simulated flow at site SB2 if the observed wind stress at site SB3 is used to drive the coastal model (Exp-F). In comparison, the jetlike flow does not affect very much the simulated currents at site SB2 if the observed wind stress at SB2 is used (Exp-E). Figures 14c,d demonstrate that the use of observed wind stress at SB3 improves the agreement between the observed and simulated currents at day 271.78. It should be noted, however, that the model results

Time sequence of sea level anomaly maps (cm), at 3.5-day intervals, corresponding to MEd over the mooring location, denoted by a circle when the vertical velocity is positive at 333-m depth or by a cross when it is negative. The white line shows the Q 0 = 0.54 σ Q ( σ Q = 2.98 × 10 −11 s −2 ) contour, the same value of Fig. 8b . Notice that north-northeast of the mooring is SEd, which eventually affects it, as shown in Fig. 10 . Fig . 10. Same as in Fig. 9 , but for SEd. Fig . 11

If a current is composed of a number of constituents with different frequencies, then quadratic friction may be analyzed at the same frequencies. The ratios of the constituents of the friction differ from the ratios for the current itself, with a classic result being that for unidirectional flow a very weak current constituent experiences proportionately 50% more friction than a strong constituent. Here, exact results for the magnitude of the friction constituents are derived and confirmed numerically. The results are applied to the tidal currents in Juan de Fuca Strait and the Strait of Georgia, showing that minor constituents experience proportionately more friction than the main constituent by an amount that varies spatially but is typically less than the classic result of 50%. For two-dimensional currents it is shown that, if there are two current constituents with the same ellipticity and major axis direction, the friction coefficients are separable functions of the current constituent ratio and the ellipticity. Some results are derived for two constituents with different ellipticity and major axis direction. For the case of two constituents with rectilinear but misaligned currents, each constituent experiences friction inclined at an angle to its current. Last, the effect of a tidal current on the bottom friction experienced by a steady flow is investigated for arbitrary relative magnitudes and directions of the tide and steady flow. In particular, the inclination of the mean friction to the mean flow is quantified.

floating matter on the sea surface were simulated by using the surface currentdata based on shipdrift data produced by Meehl. The validity of the simulation was confirmed by comparingthe results of the model with the trajectories of satellite tracked drift in the eastern North Pacific observed byKirwan et al. Some cases which originated in the western North Pacific Ocean were investigated. It was foundthat drifters set in the ocean during spring quickly migrated to North America on the strong eastward
