RISIdentifying the Characteristics of Strong Southerly Wind Events at Casey Station in East Antarctica Using a Numerical Weather Prediction System
Publisher: American Meteorological Society
Abstract: Casey Station in East Antarctica is not often subject to strong southerly flow off the Antarctic continent but when such events occur, operations at the station are often adversely impacted. Not only are the dynamics of ...
A Numerical Modeling Study of the Weather in East Antarctica and the Surrounding Southern Ocean
Publisher: American Meteorological Society
Abstract: The requirement for more detailed and accurate weather forecasts in Antarctica has steadily grown over the past decade, to the point where more sophisticated high-resolution numerical weather prediction (NWP) systems need ...
Precipitation Forecasting at High Latitudes
Publisher: American Meteorological Society
Abstract: Despite Antarctica being considered the driest continent on Earth, precipitation plays an important role in modulating activities, where reduced visibility in snow not only adversely affects flying operations but can also ...
Numerical Weather Prediction Model Performance over High Southern Latitudes
Publisher: American Meteorological Society
Abstract: Increasingly, output from numerical weather prediction (NWP) models is being used for real-time weather forecasts for the Antarctic and for Antarctic-related climate diagnostics studies. Evidence is presented that indicates ...
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 ...
An Assessment of Operational Antarctic Analyses Based on Data from the FROST Project
Publisher: American Meteorological Society
Abstract: The quality of the Antarctic operational analyses that were distributed over the Global Telecommunications System during the First Regional Observing Study of the Troposphere project special observing period of July 1994 ...
Precipitation over the Interior East Antarctic Ice Sheet Related to Midlatitude Blocking-High Activity
Publisher: American Meteorological Society
Abstract: Intermittent atmospheric blocking-high activity in the South Tasman Sea is shown to play a key role in delivering substantial snowfall as far south as at least 75°S on the central East Antarctic Ice Sheet plateau. Typically, ...
On the Reanalysis of Southern Hemisphere Charts for the FROST Project
Publisher: American Meteorological Society
Abstract: An overview is presented of the analysis procedures and problems encountered in the FROST reanalysis of weather charts poleward of latitude 50°S carried out in Hobart by the Australian Bureau of Meteorology, with advice ...
Extreme Anomalous Atmospheric Circulation in the West Antarctic Peninsula Region in Austral Spring and Summer 2001/02, and Its Profound Impact on Sea Ice and Biota
Publisher: American Meteorological Society
Abstract: Exceptional sea ice conditions occurred in the West Antarctic Peninsula (WAP) region from September 2001 to February 2002, resulting from a strongly positive atmospheric pressure anomaly in the South Atlantic coupled with ...
