Air Mass Transformation Experiment

Project Description
A mesoscale numerical simulation (35 km) of a return-flow event over the Gulf of Mexico that occurred during the Gulf of Mexico Experiment (GUFMEX) is presented in order to examine the structure and the transformation of the polar air mass and to assess the model's skill in simulating the event. The study deals with the phase of cold-air outbreak over the Gulf of Mexico and the subsequent rapid modification of the cold air mass by the underlying warm ocean, prior to the onset or return flow.
