Wind Stress is not the Ceiling of Momentum Flux to the Ocean

by L. Zhou 15 February 202111 February 2021

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.

A Direct Bridge Between Tropical Cyclones and Ocean Eddies

by L. Zhou 11 August 202016 December 2021

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 El Niño, Different Paths of North Equatorial Current

by L. Zhou 6 April 202016 December 2021

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.

Different Eddy Transport for “Lazy” and “Athletic” Observers

by L. Zhou 2 January 202012 January 2022

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.

Air-Sea Exchanges from a Wave-Following Platform

by L. Zhou 11 July 201916 December 2021

Data obtained from a wave-following platform are used to calibrate coefficients and multiple parameterizations of air-sea fluxes in swell conditions.

Route for Upwelled Kuroshio Waters into East China Sea Shelf

by L. Zhou 18 February 201911 January 2022

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.

A Comprehensive Estimate on the Entropy Budget in the Ocean

by L. Zhou 21 December 201815 November 2021

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%.

New Definition of Potential Spicity by the Least Square Method

by L. Zhou 19 November 2018

A thermodynamic function of the potential spicity is defined and it is orthogonal to the potential density in the least square sense.

Potential Spicity: From Abstract Theory to Practical Application

by L. Zhou 16 November 201816 November 2018

A method for estimating potential spicity, a thermodynamic variable in oceanography, provides a new way to describe contrasts in watermass properties.

Eddy Generation in the Central Bay of Bengal

by L. Zhou 23 October 201811 May 2022

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.
