SEASONAL SURFACE GEOSTROPHIC CURRENT IN ARAFURA-TIMOR WATERS

Jurnal Ilmu dan Teknologi Kelautan Tropis, 2013
Research on the seasonal geostrophic surface current during 2002-2011 in Arafura-Timor waters was conducted using satellite altimetry data. Those data were absolute dynamic topography and absolute geostrophic velocity data taken from Archiving Validation and Interpretation of Satellite Oceanographic data (AVISO).

Fields of perturbation of pressure, density and speeds at a geostrophic state of atmosphere

Наука. Инновации. Технологии, 2022
Introduction: Fields of perturbation of pressure, density and speeds at a geostrophic state of atmosphere The general (global) atmospheric circulation (OCA) is understood as the totality of air currents (winds), which is the horizontal extent (scale ...

Improved Surface Currents from Altimeter-Derived and Sea Surface Temperature Observations: Application to the North Atlantic Ocean

Remote Sensing
We present a study on the ocean surface currents reconstruction by merging Level-4 (L4, gap-free) altimeter-derived geostrophic currents and satellite sea surface temperature.

Geostrophic current patterns off the Egyptian Mediterranean coast [PDF]

OCEANOLOGIA, 2010
Using objectively analysed hydrographic data,currents have been calculated off the Egyptian Mediterraneancoast at the surface and at 30, 50, 75, 100, 200 and 300 mdepths for the four seasons.    The surface circulation is dominated by an anticyclonic circulationoff Salum Bay in winter, spring and summer.

Surface Vector Current Retrieval by Single-Station High-Frequency Surface Wave Radar Based on Ocean Dynamics in the Taiwan Strait

Remote Sensing
In order to address the issue of limited common coverage and high cost in mapping ocean surface vector current by two (or more) high-frequency surface wave radars, this paper proposes a single-station surface wave radar vector current inversion algorithm.

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 ...

Extreme rainfall in Madeira: the June 2023 weather event

Weather, EarlyView.
This study investigates the meteorological conditions behind the extreme precipitation event on 6 June 2023 over Madeira Island, Portugal. The event set a national daily record of 497.5mm and was unusual for occurring in early summer, as most extremes in the region occur in winter.
