Far-ranging impact of mountain waves excited over Greenland on stratospheric dehydration and rehydration
Listed in National Center for Atmospheric Research
In situ observations of reduced stratospheric water vapor combined with those of ice particle formation are rarely conducted.
Description
On the one hand, they are essential to broaden our knowledge about the formation of polar stratospheric clouds (PSCs). On the other hand, the observed profiles allow the comparison with global circulation models.
Here we report about a balloon-borne observation above Sodankyla, Finland on 26 January 2005. The frostpoint hygrometer detected layers of reduced water vapor by up to 2 ppmv from 18.5 to 23 km. Beneath, a 1-km-deep layer of increased water vapor was identified.

An aerosol backscatter sonde measured the presence of stratospheric ice clouds. According to meteorological analysis the PSCs were formed upstream above the east coast of Greenland due to mountain wave-induced cooling. The inertia-gravity waves generated a large and persistent stratospheric wake far downstream of Greenland and led to the observed dehydration.
Comparing the most recent ERA5 data with operational analyses from 2005, we find an improved representation of mesoscale internal gravity waves, dehydration and PSC formation for this particular event.
