Meridional Ekman Heat Transport: Estimates from Satellite Data

Journal of Physical Oceanography, 1995
Abstract Analyses of satellite-derived SSM/I winds and AVHRR sea surface temperatures are used to compute weekly estimates of global meridional ocean Ekman heat transport for the 4-year period 1987–1991. The heat transport is consistently poleward throughout the year over the Atlantic and much of the Pacific between 30°S and 30°N and equatorward at ...

The transport in the Ekman surface layer on the spherical Earth

Journal of Marine Research, 2002
The modification of the transport in the Ekman layer on the f-plane due to the Coriolis parameter’s variation with latitude and the curvature of Earth’s surface is analyzed by considering the temporal changes in the angular momentum. The latter plays the role of a dynamical variable of the model, replacing the zonal velocity component, and drag is ...

Estimating the Meridional Ekman Transport at 14.5 N in the Atlantic Ocean [PDF]

, 2015
The meridional Ekman transport across a transatlantic section at 14.5 N is estimated from different wind products and in-situ observational data. As a well-established method, the wind-based approach gives a meridional Ekman transport of 5.8 ± 0.4 Sv ...

The Balance of Geostrophic and Ekman Transports in the Tropical Atlantic Ocean

Journal of Physical Oceanography, 1983
Abstract Hydrographic station data from 24°N, 8°N, 8°S and 24°S in the Atlantic Ocean are used to calculate geostrophic transport in eight layers separated by isopycnal surfaces. In the upper ocean, the geostrophic transport is strongly northward across 8°S and strongly southward across 8°N resulting in a geostrophic convergence of ∼25 × 106 m2 s−1 in ...

Effects of Ekman Transport on the NAO Response to a Tropical Atlantic SST Anomaly

Journal of Climate, 2006
Abstract A recent study showed that a tropical Atlantic sea surface temperature (SST) anomaly induces a significant coupled response in late winter [February–April (FMA)] in a coupled model, in which an atmospheric general circulation model is coupled to a slab mixed layer ocean model (AGCM_ML). The coupled response comprises a dipole in

The Role of Ekman Ocean Heat Transport in the Northern Hemisphere Response to ENSO

Journal of Climate, 2008
Abstract The influence of oceanic Ekman heat transport (Qek) on air–sea variability associated with ENSO teleconnections is examined via a pair of atmospheric general circulation model (AGCM) experiments. In the mixed layer model (MLM) experiment, observed sea surface temperatures (SSTs) for the years 1950–99 are specified over the ...

Pollutant Dispersion in the Ekman Layer Using Moment-Reduced Transport Equations

1983
The program MODIS (Moment Distribution) is designed to extend the Gaussian plume model up to the range of about 102 km. Numerical experiments with stationary solutions are reported to show reliability and accuracy (essentially dependent on the grid Peclet number) of the results. The influence of the Coriolis force on the ground centre line of the plume

The Time-varying Characteristics of the Meridional Ekman Heat Transport for the World Ocean

Journal of Physical Oceanography, 1993
Abstract The time-varying meridional Ekman heat transport for the World Ocean is calculated for the 30-year period 1960–1989 using wind stress and sea surface temperature data from the Comprehensive Ocean–Atmosphere Data Set The average monthly heat transports are dominated by poleward transport of heat in the tropical Pacific and Atlantic oceans.
