Nature Communications, 2017 Satellite altimeters resolution poorly capture mesoscale signals in the upper ocean. Here, the authors analyse shipboard Acoustic Doppler Current Profiler measurements from the northwest Pacific, and show that balanced geostrophic flows and unbalanced ...

Energetics of the global ocean: The role of mesoscale eddies [PDF]
, 2016 This article reviews the energy cycle of the global ocean circulation, focusing on the role of baroclinic mesoscale eddies. Two of the important effects of mesoscale eddies are: (i) the flattening of the slope of large-scale isopycnal surfaces by the ...

Nonlinearity in a dynamo [PDF]
, 2009 Using a rotating flat layer heated from below as an example, we consider effects which lead to stabilizing an exponentially growing magnetic field in magnetostrophic convection in transition from the kinematic dynamo to the full non-linear dynamo.

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract As near‐surface wind speed (NSWS) largely controls wind power generation, robust projection is vital to wind energy planning and broader sustainability goals. However, the predictive skill of climate models for NSWS remains uncertain. Analysis of Coupled Model Intercomparison Project Phase 6 simulations shows that the models reproduce the mean

Ciencias Marinas, 2010 We estimated the net flux of inorganic phosphorus (kg P d–1) due to geostrophic transport in the upper 100 m of a control volume (CV) off Baja California (Mexico) during 2003 and 2004. The influence of this flux on integrated primary production (IPP) in

Laminar and weakly turbulent oceanic gravity currents performing inertial oscillations [PDF]
Ocean Science, 2012 The small scale dynamics of a weakly turbulent oceanic gravity current is determined. The gravity current considered is initially at rest and adjusts by performing inertial oscillations to a geostrophic mean flow.

On the global estimates of geostrophic and Ekman surface currents [PDF]
Limnology and Oceanography: Fluids and Environments, 2013 Lay AbstractA fundamental goal of physical oceanography is to provide a primary description of global ocean circulation. Historically, ocean surface currents were inferred from ship drift measurements, mainly in relation with navigational requirements. Ocean circulation was shown to play an important role in the last decades for studying the transport ...

Estimation of orographically induced wave drag in the stable boundary layer during the CASES-99 experimental campaign [PDF]
, 2009 This paper addresses the quantification of gravity wave drag due to small hills in the stable boundary layer. A single column atmospheric model is used to forecast wind and temperature profiles in the boundary layer.

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract This study investigates mechanisms by which distinct intraseasonal oscillation modes drive regional persistent extreme precipitation events over South China during the rainy season. Based on periodic characteristics of 54 such events, two dominant modes are identified: 12–20‐day (type‐1) and 25–50‐day (type‐2) oscillations. Although comparable

The Propagation of Internal Waves in a Geostrophic Current
Journal of Physical Oceanography, 1981 Abstract The paper presents the WKB theory of internal wave propagation in a large-scale geostrophic mean flow with vertical as well as horizontal shear. As an application a mean flow with isopycnals having constant slope but arbitrary spacing is considered and the behavior of waves at turning points and critical layers is discussed.
