The ocean is mainly driven by wind stress, but simultaneous observations show that the gain of momentum flux by the ocean can be larger than the wind stress due to the influence of ocean waves.
Tropical cyclones can inject potential vorticity directly into ocean eddies—an alternative way for tropical cyclones to leave fingerprints on the ocean besides the traditional near-inertial wave.
Different types of El Niño have different impacts on the North Equatorial Current Bifurcation and can be extended to ocean circulations in the Pacific and the global climate system.
Two specifications of fluid dynamics—taking measurements at a fixed point and following a fluid parcel—are compared for quantifying eddy transport in the ocean.
Data obtained from a wave-following platform are used to calibrate coefficients and multiple parameterizations of air-sea fluxes in swell conditions.
A simple algorithm obtains short-term variations in upwelling, which show that the subsurface Kuroshio waters can upwell directly into the East China Sea shelf under the advection of the Kuroshio.
An analysis of the energy budget in the ocean estimates the Carnot work to be 110 terawatts and the ocean’s Carnot efficiency to be 0.86%.
A thermodynamic function of the potential spicity is defined and it is orthogonal to the potential density in the least square sense.
A method for estimating potential spicity, a thermodynamic variable in oceanography, provides a new way to describe contrasts in watermass properties.
Eddies in the central Bay of Bengal are generated near the eastern boundary of the basin, related to equatorial wind forcing, nonlinearity, and the topographic “bump” of Myanmar.
