The Amr Adaptive Grid Model And Its Use In The Study Of The 2002 Anomalous Polar Vortex
Abstract
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.
