其他摘要：An adaptive grid model, called AMR (Adaptive Mesh refinement) is used for the first time to study the stratosphere over the Southernn Hemisphere. The model was used to study the evolution of potencial vorticity (PV), a passive dynamical tracer, during the particularly perturbed 2002 Antarctic ozone hole season. The AMR-CTM is a mechanistic model driven by winds obtained from an operational data assimilation model and reanalysis run by the European Centre for Midrange Weather Forecasting (ECMWF). The current model characteristics will be introduced and the results of the 2002 event, together with observations and independent reanalysis products will be presented, in order to demonstrate the capabilities of this new approach to modeling fluid behavior as the described here.
