Nighttime mesospheric ozone enhancements during the 2002 southern hemispheric major stratospheric warming
Christine Smith-Johnsen, Yvan Orsolini, Frode Stordal +2
Sudden Stratospheric Warmings (SSW) affect the chemistry and dynamics of the middle atmosphere. Major warmings occur roughly every second winter in the Northern Hemisphere (NH), bu…
Modelling the descent of nitric oxide during the elevated stratopause event of January 2013
Yvan J. Orsolini, Varavut Limpasuvan, Kristell Pérot +5
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 Su…
Observations of planetary waves in the mesosphere-lower thermosphere during stratospheric warming events
N. H. Stray, Y. J. Orsolini, P. J. Espy +2
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 der…
