Modelling the descent of nitric oxide during the elevated stratopause event of January 2013
Orsolini, Yvan; Limpasuvan, Varavut; Pérot, Kristell; Espy, Patrick Joseph; Hibbins, Robert; Lossow, Stefan; Raaholt Larsson, Katarina; Murtagh, Donal (Peer reviewed; Journal article, 2017-03)Using simulations with a whole-atmosphere chemistry-climate model nudged by meteorological analyses, global satellite observations of nitrogen oxide (NO) and water vapour by the Sub-Millimetre Radiometer instrument (SMR), ... -
Observations of planetary waves in the mesosphere-lower thermosphere during stratospheric warming events
Stray, Nora Henriette; Orsolini, Yvan; Espy, Patrick Joseph; Limpasuvan, Varavut; Hibbins, Robert (Peer reviewed; Journal article, 2015-05-04)This study investigates the effect of stratospheric sudden warmings (SSWs) on planetary wave (PW) activity in the mesosphere–lower thermosphere (MLT). PW activity near 95 km is derived from meteor wind data using a chain ... -
On the composite response of the MLT to major sudden stratospheric warming events with elevated stratopause
Limpasuvan, Varavut; Orsolini, Yvan; Chandran, Amal; Garcia, Rolando R.; Smith, Anne K. (Peer reviewed; Journal article, 2016-05)Based on a climate-chemistry model (constrained by reanalyses below ~50 km), the zonal-mean composite response of the mesosphere and lower thermosphere (MLT) to major sudden stratospheric warming events with elevated ...
