Tropical stratospheric gravity wave activity and relationships to clouds

Intercomparison of stratospheric gravity wave observations with AIRS and IASI

Gravity waves are an important driver for the atmospheric circulation and have substantial impact on weather and climate. Satellite instruments offer excellent opportunities to study gravity waves on a global scale. This study focuses on observations from the Atmospheric Infrared Sounder (AIRS) onboard the National Aeronautics and Space Administration Aqua satellite and the Infrared Atmospheric...

Stratospheric gravity wave simulation over Greenland during 24 January 2005

[1] The ‘‘Advanced Regional Prediction System’’ forecast model is extended up to the stratopause and over the entire hemisphere to simulate gravity waves during 24 January 2005. With a 15-km horizontal resolution, the simulation produces dominant gravity wave features near Eastern Greenland that are associated mainly with orographic forcing by the Greenland terrain. The simulated wave temperatu...
