abstract = {Gravity waves (GWs) are one of the most important drivers
of middle atmospheric circulations and strongly affect the
polar vortex of the winter hemisphere. These waves are of
comparatively small horizontal scales and are generated by a
multitude of processes, of which wind flow over orography
and convection are the most common. The resolution of
today’s climate models is, however, too coarse for
resolving GWs explicitly; therefore, they need to be
parameterized within long-term climate projections. These
parameterizations are a first approximation of the GW’s
effect on the atmosphere. A technical shortcoming common to
parameterization schemes is their vertical column-wise
application without the possibility of horizontal
communication between adjacent grid cells due to
computation-cost intensity. Hence, parametrization schemes
do not account for the horizontal propagation of GWs, even
though many studies show the far propagation of gravity
waves (and especially mountain waves, MWs) from their
sources. This horizontal propagation transports the momentum
carried by the orographic GWs away from regions of high
orographic variability; thereby spreading the effect of the
orography on the atmosphere dynamics. Studies attribute
highvariability and model biases in the southern hemisphere
to this lack of horizontal propagation of mountain waves
within climate models.},
