Seasonal Variation of Gravity Wave Sources From Satellite Observation

Abstract

Recent high-resolution satellite observations of gravity waves in the middle atmosphere have shown correlations with the strength of the stratospheric jet stream, surface topography, and tropical convection. Seasonal variations of wave-induced stratospheric radiance variances are often the manifestations of modulations of these sources and refractive influences. In this paper, we focus on the seasonal climatology of gravity waves observed by the UARS MLS, while also showing some new results from GPS and AMSU instruments. Our analysis is aided by MWFM modeling of mountain waves at high latitudes and CMAP precipitation indices in the subtropics to provide a clearer picture of global gravity wave dynamics.
