RISSensitivity of the Amundsen Sea Low to Stratospheric Ozone Depletion
Publisher: American Meteorological Society
Abstract: ramatic sea ice loss in the Amundsen and Bellingshausen Seas and regional warming in West Antarctica and the Antarctica Peninsula have been observed over the last few decades. Both of these changes are strongly influenced ...
Strong Trends in the Skill of the ERA-40 and NCEP–NCAR Reanalyses in the High and Midlatitudes of the Southern Hemisphere, 1958–2001
Publisher: American Meteorological Society
Abstract: The European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) and the National Centers for Environmental Prediction?National Center for Atmospheric Research (NCEP?NCAR) reanalysis (NCEP1) data are ...
Decadal Variability of the ENSO Teleconnection to the High-Latitude South Pacific Governed by Coupling with the Southern Annular Mode
Publisher: American Meteorological Society
Abstract: Decadal variability of the El Niño?Southern Oscillation (ENSO) teleconnection to the high-latitude South Pacific is examined by correlating the European Centre for Medium-Range Weather Forecasts (ECMWF) 40-yr Re-Analysis ...
Atmospheric Moisture and Cloud Cover Characteristics Forecast by AMPS
Publisher: American Meteorological Society
Abstract: Antarctic Mesoscale Prediction System (AMPS) forecasts of atmospheric moisture and cloud fraction (CF) are compared with observations at McMurdo and Amundsen?Scott South Pole station (hereafter, South Pole station) in ...
Extratropical Southern Hemisphere Synchronous Pressure Variability in the Early Twentieth Century
Publisher: American Meteorological Society
Seasonal Zonal Asymmetries in the Southern Annular Mode and Their Impact on Regional Temperature Anomalies
Publisher: American Meteorological Society
Abstract: he Southern Hemisphere annular mode (SAM) is the dominant mode of climate variability in the extratropical Southern Hemisphere. Representing variations in pressure and the corresponding changes to the circumpolar zonal ...
A New Monthly Pressure Dataset Poleward of 60°S since 1957
Publisher: American Meteorological Society
Abstract: AbstractThis study presents a new monthly pressure dataset poleward of 60°S, from 1957 to 2016, based on a kriging interpolation from observed pressure anomalies across the Antarctic continent. Overall, the reconstruction ...
Historical SAM Variability. Part I: Century-Length Seasonal Reconstructions
Publisher: American Meteorological Society
Abstract: Seasonal reconstructions of the Southern Hemisphere annular mode (SAM) index are derived to extend the record before the reanalysis period, using station sea level pressure (SLP) data as predictors. Two reconstructions ...
An Exceptional Summer during the South Pole Race of 1911-1912
Publisher: American Meteorological Society
Abstract: e race for the South Pole during the summer of 1911-1912 was marked by exceptionally high temperature and pressure anomalies experienced by both Amundsen and Scott.
Historical SAM Variability. Part II: Twentieth-Century Variability and Trends from Reconstructions, Observations, and the IPCC AR4 Models
Publisher: American Meteorological Society
Abstract: This second paper examines the Southern Hemisphere annular mode (SAM) variability from reconstructions, observed indices, and simulations from 17 Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report ...
