Heating of the auroral ionosphere by traveling ionospheric disturbances initiated by atmospheric gravity waves
ionospheric dynamics plasma physics auroral phenomena
2015/8/28
In the presence of perturbations of the thermospheric auroral region produced by traveling ionospheric disturbances during the propagation of atmospheric gravity waves, an analytical expression of the...
Can gravity waves significantly impact PSC occurrence in the Antarctic?
gravity waves significantly PSC occurrence Antarctic
2009/12/3
A combination of POAM III aerosol extinction and CHAMP RO temperature measurements are used to examine the role of atmospheric gravity waves in the formation of Antarctic Polar Stratospheric Clouds (P...
Cloud's Center of Gravity – a compact approach to analyze convective cloud development
Cloud's Center of Gravity convective cloud development
2009/3/12
As cloud resolving models become more detailed, with higher resolution outputs, it is often complicated to isolate the physical processes that control the cloud attributes. Moreover, due to the high d...
Analysis of a jet stream induced gravity wave associated with an observed ice cloud over Greenland
jet stream gravity wave ice cloud Greenland
2009/3/3
A polar stratospheric ice cloud (PSC type II) was observed by airborne lidar above Greenland on 14 January 2000. It was the unique observation of an ice cloud over Greenland during the SOLVE/THESEO 20...
On the spectrum of vertically propagating gravity waves generated by a transient heat source
gravity waves transient heat source
2009/2/27
It is commonly believed that cumulus convection preferentially generates gravity waves with tropospheric vertical wavelengths approximately twice the depth of the convective heating. Individual cumulo...
Formation of ice supersaturation by mesoscale gravity waves

2009/2/5
A case study to investigate the properties of inertia-gravity waves in the upper troposphere/lower stratosphere has been carried out over Northern Germany during the occurrence of an upper tropospheri...
Some experimental constraints for spectral parameters used in the Warner and McIntyre gravity wave parameterization scheme
experimental constraints spectral parameters McIntyre gravity wave parameterization scheme
2009/1/15
In order to incorporate the effect of gravity waves (GWs) on the atmospheric circulation most global circulation models (GCMs) employ gravity wave parameterization schemes. To date, GW parameterizatio...
Wind-profiler observations of gravity waves produced by convection at mid-latitudes
