abstract = {Polar stratospheric clouds (PSCs) are a driver for ozone
depletion in the lower polar stratosphere. They provide
surface for heterogeneous reactions activating chlorine and
bromine reservoir species during the polar night. The
large-scale effects of PSCs are represented by means of
parameterisations in current global chemistry–climate
models, but one process is still a challenge: the
representation of PSCs formed locally in conjunction with
unresolved mountain waves. In this study, we investigate
direct simulations of PSCs formed by mountain waves with the
ICOsahedral Nonhydrostatic modelling framework (ICON) with
its extension for Aerosols and Reactive Trace gases (ART)
including local grid refinements (nesting) with two-way
interaction. Here, the nesting is set up around the
Antarctic Peninsula, which is a well-known hot spot for the
generation of mountain waves in the Southern Hemisphere. We
compare our model results with satellite measurements of
PSCs from the Cloud-Aerosol Lidar with Orthogonal
Polarization (CALIOP) and gravity wave observations of the
Atmospheric Infrared Sounder (AIRS). For a mountain wave
event from 19 to 29 July 2008 we find similar structures of
PSCs as well as a fairly realistic development of the
mountain wave between the satellite data and the ICON-ART
simulations in the Antarctic Peninsula nest. We compare a
global simulation without nesting with the nested
configuration to show the benefits of adding the nesting.
Although the mountain waves cannot be resolved explicitly at
the global resolution used (about 160 km), their effect
from the nested regions (about 80 and 40 km) on the global
domain is represented. Thus, we show in this study that the
ICON-ART model has the potential to bridge the gap between
directly resolved mountain-wave-induced PSCs and their
representation and effect on chemistry at coarse global
resolutions.},
