 He has made contributions to defining aspects of U.S. science policy.Having helped identify the need to improve numerical weather prediction (NWP) for the Antarctic, Bromwich has been influential in the development and evaluation of the Antarctic Mesoscale Prediction System (AMPS).In April 2001 AMPS was one of four weather models used to predict a window of opportunity for the emergency medical evacuation of Ronald Shemenski from the Amundsen–Scott South Pole Station.
