Analysis and forecast of the surface currents in the Okhotsk Sea on the base of observations on drift of buoys

Известия ТИНРО, 2017
Data of observations on drifting buoys in the western Okhotsk Sea are presented. Quasi-stochastic mode of the buoys drift under forcing of atmospheric cyclone is noted.

Benefits of radar-derived surface current assimilation for South of Africa ocean circulation

Geoscience Letters, 2021
The oceanic circulation south of Africa is characterised by a complex dynamics with a strong variability due to the presence of the Agulhas current and numerous eddies.

Bathymetry-constrained ocean geostrophic currents play a key role in shaping the sea ice circulation in the Canada Basin, Arctic Ocean

Environmental Research Letters
Satellite-based observations and a pan-Arctic coupled sea ice-ocean model are utilized to study the effect of ocean geostrophic currents on large-scale sea ice circulation in the Canada Basin, Arctic Ocean.

Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

Present and future downslope windstorms in the Scandinavian Mountains from a kilometre‐scale climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Kilometre‐scale climate simulations for Scandinavia indicate the importance of high resolution for reproducing downslope windstorms (DWs). Scandinavian DWs on average induce a limited local warming but with large variability due to the region's complex orography.

A new smoother method for treating different timescales in variational data assimilation for coupled systems

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We propose a new method for treating different timescales in coupled variational data assimilation for atmosphere–ocean models. The approach involves a series of short‐window coupled assimilations (red arrows in the schematic) followed by a long‐window correction to the ocean fields (blue arrow).

On the Structure and Kinematics of an Algerian Eddy in the Southwestern Mediterranean Sea

Remote Sensing, 2021
An Algerian Eddy, anticyclonic vortex generated by the instability of the Algerian Current in the southwestern Mediterranean Sea, is studied using data provided by drifters (surface currents), Argo floats (temperature and salinity profiles ...

Wind Forced Variability in Eddy Formation, Eddy Shedding, and the Separation of the East Australian Current [PDF]

, 2017
The East Australian Current (EAC), like many other subtropical western boundary currents, is believed to be penetrating further poleward in recent decades.

Stratospheric and tropospheric seasonality and its implications for observation requirements in numerical weather prediction

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Daily time series of zonal‐mean zonal wind (m·s−1) at 10 hPa and 60° N from 1950 to 2021 from the ERA5 reanalysis. This shows huge variability in some seasons and very little in others. We provide evidence that high‐level observations, radiosonde and satellite, are more important during the extended winter season with its very large variability ...
