RISWRF Model Experiments on the Antarctic Atmosphere in Winter
Publisher: American Meteorological Society
Abstract: he standard and polar versions 3.1.1 of the Weather Research and Forecasting (WRF) model, both initialized by the 40-yr ECMWF Re-Analysis (ERA-40), were run in Antarctica for July 1998. Four different boundary layer?surface ...
Antarctic Low-Tropospheric Humidity Inversions: 10-Yr Climatology
Publisher: American Meteorological Society
Abstract: umidity inversions are nearly permanently present in the coastal Antarctic atmosphere. This is shown based on an investigation of statistical characteristics of humidity inversions at 11 Antarctic coastal stations using ...
Mesoscale Modeling of the Atmosphere over Antarctic Sea Ice: A Late-Autumn Case Study
Publisher: American Meteorological Society
Abstract: Atmospheric flow over Antarctic sea ice was simulated applying a polar version of the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (Polar MM5). The simulation ...
Horizontal Moisture Transport Dominates the Regional Moistening Patterns in the Arctic
Publisher: American Meteorological Society
Abstract: Along with the amplified warming and dramatic sea ice decline, the Arctic has experienced regionally and seasonally variable moistening of the atmosphere. Based on reanalysis data, this study demonstrates that the regional ...
Air Moisture Climatology and Related Physical Processes in the Antarctic on the Basis of ERA5 Reanalysis
Publisher: American Meteorological Society
Arctic Humidity Inversions: Climatology and Processes
Publisher: American Meteorological Society
Abstract: AbstractThe occurrence and characteristics of Arctic specific humidity inversions (SHIs) were examined on the basis of two reanalyses (ERA-Interim and JRA-55) and radiosonde sounding data from 2003 to 2014. Based on physical ...
Evidence of Very Shallow Summertime Katabatic Flows in Dronning Maud Land, Antarctica
Publisher: American Meteorological Society
Abstract: he three-axis ?Latan-3? Doppler sodar was operated near the Finnish Antarctic station Aboa in Dronning Maud Land (73.04°S, 13.40°W) in the austral summer of 2010/11. The measuring site is located at a practically flat, ...
Evaluation of Polar WRF from Modeling the Atmospheric Boundary Layer over Antarctic Sea Ice in Autumn and Winter
Publisher: American Meteorological Society
Abstract: egional simulations of the atmospheric boundary layer over Antarctic sea ice that have been adequately validated are rare. To address this gap, the authors use the doubly nested Polar Weather Research and Forecasting (Polar ...
Features of Extreme Precipitation at Progress Station, Antarctica
Publisher: American Meteorological Society
Abstract: AbstractObserved daily precipitation data were used to investigate the characteristics of precipitation at Antarctic Progress Station and synoptic patterns associated with extreme precipitation events during the period ...
The Melting Arctic and Midlatitude Weather Patterns: Are They Connected?
Publisher: American Meteorological Society
Abstract: he potential of recent Arctic changes to influence hemispheric weather is a complex and controversial topic with considerable uncertainty, as time series of potential linkages are short (<10 yr) and understanding involves ...
