摘要: A 6 year (2007-2013) temperature data set from the Solar Occultation for Ice Experiment (SOFIE) onboard Aeronomy of in Mesosphere (AIM) satellite is used to extract gravity waves (GWs) polar stratosphere and mesosphere both hemispheres. These are continuous regions. The monthly mean GW potential energy (PE) increases exponentially with a scale height similar 13 km upper mesosphere. GWs stronger winter than summer exhibit strong annual variation. southern region (SPR) northern (NPR) except months. This likely because there longer-lasting zonal wind jets SPR stratosphere, as revealed Modern-Era Retrospective analysis Research Applications (MERRA) data. longitudinal variations PE consistent elevated In mesosphere, do not vary significantly. correlations between column ice water content (IWC, an indicator cloud) variations.
