In response to needs of the U.S. Antarctic Program (USAP), the National Center for Atmospheric Research and the Byrd Polar Research Center of the Ohio State University have created the Antarctic Mesoscale Prediction System (AMPS): an experimental, real-time mesoscale modeling system covering Antarctica. AMPS was originally designed to support flight forecasters at McMurdo Station, to serve scientific programs around the continent, and to serve as a vehicle for the deployment of polar physical parameterizations. Since its creation in 2000, AMPS has been producing high-resolution forecasts (grids to 3.3 km) with a mesoscale model tuned for the polar atmosphere, the Polar MM5. This version features a number of modifications to improve the simulation of conditions and processes in Antarctica.
The scope of AMPS services has broadened since its inception to encompass guidance for many countries with Antarctic programs and installations. In addition to this, AMPS has assisted emergency rescue operations and scientific field programs. The history, capabilities, and performance of AMPS will be described, and the applications of this unique NWP system in Antarctic crisis support and international service will be highlighted.
