Stratospheric Weather Impacts Light Species at Great Heights

Using three simulation models (NAVGEM, TIE-GCM and TIME-GCM) and measurements obtained from the TIMED/SABER instrument, Jones et al. [2020] examine the effects of sudden stratospheric warmings (SSWs) on minor constituents in the upper mesosphere and thermosphere. High latitude, wintertime enhanced planetary wave activity in the troposphere and stratosphere changes the circulation and local […]
