Technical Note: SWIFT - A Fast Semi-Empirical Model For Polar Stratospheric Ozone Loss
An extremely fast model to estimate the degree of stratospheric ozone depletion during polar winters is described. It is based on a set of coupled differential equations that simulate the seasonal evolution of vortex-averaged hydrogen chloride (HCl), nitric acid (HNO3), chlorine ni5 trate (ClONO2), active forms of chlorine (ClOx=Cl+ClO+ 2ClOOCl) and ozone (O3) on isentropic levels within the po...

متن کاملSimulation of polar ozone depletion: An update
We evaluate polar ozone depletion chemistry using the specified dynamics version of the Whole Atmosphere Community Climate Model for the year 2011. We find that total ozone depletion in both hemispheres is dependent on cold temperatures (below 192 K) and associated heterogeneous chemistry on polar stratospheric cloud particles. Reactions limited to warmer temperatures above 192 K, or on binary ...
متن کاملThe impact of polar stratospheric ozone loss on Southern Hemisphere stratospheric circulation and climate
The impact of polar stratospheric ozone loss resulting from chlorine activation on polar stratospheric clouds is examined using a pair of model integrations run with the fully coupled chemistry climate model UM-UKCA. Suppressing chlorine activation through heterogeneous reactions is found to produce modelled ozone differences consistent with observed ozone differences between the present and pr...
متن کاملStratospheric Polar Vortices
GM000887-PO-Waugh. f The intense cyclonic vortices that form over the winter pole are one of the most prominent features of the stratospheric circulation. The structure and dynamics of these “polar vortices” play a dominant role in the winter and spring stratospheric circulation and are key to determining distribution of trace gases, in particular ozone, and the couplings between the stratosphe...
