Polar Atmospheric River (AR) Scale Forecast Products over Antarctica
A team of researchers led by Scripps Institution of Oceanography at the University of California San Diego has created a scale to characterize the strength and impacts of “atmospheric rivers” mainly for the mid-latitudes. This Polar AR scale utilize an adapted version of the original AR Scale... -
Gridded Polar Atmospheric River (AR) scale dataset
The gridded polar Atmospheric River (AR) scale dataset is calculated based on the extended AR scale developed at the Center for Western Weather and Water Extremes (CW3E) at Scripps Institution of Oceanography, which ranks ARs from AR P1 to AR5 at each grid point based on ERA5 data (1°×1°) at... -
Year of Polar Prediction in the South Hemisphere: Targeted Observing Period Antarctic Forecast Discussion, 2022.
The following PDFs contain a forecast product created in support of the Year of Polar Prediction – Southern Hemisphere (YOPP-SH) Targeted Observing Period (TOP). The forecasts were produced by Art Cayette from the Naval Information Warfare Center, Naval Weapons Station, in Charleston, SC.... -
Selected austral summer Atmospheric River cases over the Antarctic Peninsula, 2001 - 2022.
Six-hourly IVT maps from Polar WRF D01 simulations (30 km resolution) are provided for all selected AR cases over the Antarctic Peninsula from 2001 to 2022, based on the gridded Polar AR scale dataset. Full PWRF outputs are included for five representative AR events, while selected surface...
