RISA Mean Synoptic View of the Subantarctic Front South of Australia
Publisher: American Meteorological Society
Abstract: A mean synoptic view of the subantarctic front (SAF) is obtained from current meter and hydrographic data by averaging absolute and baroclinic velocity measurements in bins defined by a cross-stream coordinate that moves ...
Eddy Variability and Energetics from Direct Current Measurements in the Antarctic Circumpolar Current South of Australia
Publisher: American Meteorological Society
Abstract: Two-year time series measurements of current velocity and temperature in the Subantarctic Front (SAF) south of Australia from 1993 to 1995 provide estimates of eddy fluxes of heat and momentum across the Antarctic Circumpolar ...
Bermuda’s Tale of Two Time Series: Hydrostation S and BATS
Publisher: American Meteorological Society
Abstract: This paper describes the oceanic variability at Bermuda between 1989 and 1999, recorded in two overlapping hydrographic time series. Station S and Bermuda Atlantic Time Series Study (BATS), which are 60 km apart, both show ...
Ocean Response and Feedback to the SST Dipole in the Tropical Atlantic
Publisher: American Meteorological Society
Abstract: The equatorial SST dipole represents a mode of climate variability in the tropical Atlantic Ocean that is closely tied to cross-equatorial flow in the atmosphere, from the cold to the warm hemisphere. It has been suggested ...
Mixing Variability in the Southern Ocean
Publisher: American Meteorological Society
Abstract: key remaining challenge in oceanography is the understanding and parameterization of small-scale mixing. Evidence suggests that topographic features play a significant role in enhancing mixing in the Southern Ocean. This ...
Internal Waves and Mixing near the Kerguelen Plateau
Publisher: American Meteorological Society
Abstract: n the stratified ocean, turbulent mixing is primarily attributed to the breaking of internal waves. As such, internal waves provide a link between large-scale forcing and small-scale mixing. The internal wave field north ...
Detecting and Characterizing Ekman Currents in the Southern Ocean
Publisher: American Meteorological Society
Abstract: his study presents a unique array of velocity profiles from Electromagnetic Autonomous Profiling Explorer (EM-APEX) profiling floats in the Antarctic Circumpolar Current (ACC) north of Kerguelen. The authors use these ...
On the Leeuwin Current System and Its Linkage to Zonal Flows in the South Indian Ocean as Inferred from a Gridded Hydrography
Publisher: American Meteorological Society
Abstract: he Leeuwin Current System (LCS) along the coast of Western Australia consists of the poleward-flowing Leeuwin Current (LC), the equatorward-flowing Leeuwin Undercurrent (LUC), and neighboring flows in the south Indian Ocean ...
Near-Surface Salinity Reveals the Oceanic Sources of Moisture for Australian Precipitation through Atmospheric Moisture Transport
Publisher: American Meteorological Society
Abstract: The long-term trend of sea surface salinity (SSS) reveals an intensification of the global hydrological cycle due to human-induced climate change. This study demonstrates that SSS variability can also be used as a measure ...
An Assessment of Numerical Weather Prediction–Derived Low-Cloud-Base Height Forecasts
Publisher: American Meteorological Society
Abstract: s demand for flight operations in Antarctica grows, accurate weather forecasting of cloud properties such as extent, cloud base, and cloud-top altitude becomes essential. The primary aims of this work are to ascertain ...
