AMPS— The Antarctic Mesoscale Prediction System
• Real-time WRF to support US Antarctic Program Antarctic weather forecasting and science
• AMPS effort includes:
(i) WRF polar performance analysis
(ii) Physics improvement

Motivations for AMPS: Antarctic Forecasting Needs
– Weaknesses seen in the NWP available to the McMurdo forecasters (circa 2000)
The Antarctic Weather Forecasting Workshop (May 2000, BPRC)
1) Inadequate resolution
To capture mesoscale wx features
To capture local topography
2) Need to improve high-latitude model performance
Better physics/parameterizations neededfor the Antarctic PBL / troposphere
– Proposed: A real-time mesoscale modeling system tailored for the USAP forecasters
