Detecting surface geostrophic currents using wavelet filter from satellite geodesy

Science in China Series D: Earth Sciences, 2007
According to the features of spatial spectrum of the dynamic ocean topography (DOT), wavelet filter is proposed to reduce short-wavelength and noise signals in DOT. The surface geostrophic currents calculated from the DOT models filtered by wavelet filter in global and Kuroshio regions show more detailed information than those from the DOT models ...

Compatible finite element methods for numerical weather prediction [PDF]

, 2014
This article takes the form of a tutorial on the use of a particular class of mixed finite element methods, which can be thought of as the finite element extension of the C-grid staggered finite difference method.

Finer Vertical Resolution Improves the Sudden Stratospheric Warming Prediction Through Better Representing Planetary Waves

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Sudden stratospheric warmings (SSWs) strongly impact tropospheric weather, yet their accurate prediction remains a significant challenge. This study investigates the predictability of SSWs in the Whole Atmosphere Community Climate Model with different vertical resolutions.

Reduced cooling in the Norwegian Atlantic Slope Current: investigating mechanisms of change from 30 years of observations [PDF]

Ocean Science
The Norwegian Atlantic Current (NwAC) is a principal conduit for poleward heat and salt transport within the Atlantic Meridional Overturning Circulation (AMOC) and plays a key role of water mass transformation in the Nordic Seas. Its variability exerts a

Rainfall and Rain‐on‐Snow Events Over Greenland in Summer: Climatology, Trends, Synoptics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Rain‐on‐snow (ROS) events in the Arctic can lead to major impacts on the snow cover, cryosphere and environment. During the last decades, these events have significantly increased, mostly due to climate change. Here, we use outputs from the regional climate model MAR (version 3.14) driven by the ERA5 reanalysis at 10‐km resolution over ...

Mesoscale ageostrophic circulations associated with baroclinic jet streaks [PDF]

, 1984
Studies of ageostrophic motion attending jet streaks and convection are examined. Various types of dynamical experiments are carried out with the hybrid isentropic-sigma coordinate model. The effects of vorticity and static stability distributions on the

Seismic Stratigraphy of Eocene–Recent Mixed Depositional Systems on the SE New Zealand Continental Margin, Great South Basin

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The continental margin of SE New Zealand is strongly influenced by the Southland Current and associated water masses. This new seismic stratigraphic study of the margin has revealed a range of depositional mounds and erosional channels that document the close interaction of turbidity and bottom currents in shaping the margin from the Mid‐Eocene onward.

Intermediate Western Boundary Current speeds from the southeastern Brazilian margin: A 16,000‐year record from grain‐size evidence

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract This study presents a high‐resolution reconstruction of the Antarctic Intermediate Water (AAIW) transport variability on the southeastern Brazilian continental margin over the last 16,000 years BP, based on grain‐size analysis. Variations of sortable silt (SS¯$$ \overline{SS} $$) are interpreted as changes in flow speed of the Intermediate ...
