  • The double peak in upwelling and heating in the tropical lower stratosphere. 

    Ming, Alison; Hitchcock, Adam Peter; Haynes, Peter Howard (American Meteorological SocietyJournal of the Atmospheric Sciences, 2016-04-15)
    The processes responsible for double peak latitudinal structures in the time averaged tropical lower stratospheric upwelling, centred near 70hPa and 20º N–S, previously noted in ERA-Interim and other reanalysis and model ...

  • The downward influence of stratospheric sudden warmings 

    Hitchcock, Adam Peter; Simpson, Isla R (Journal of the Atmospheric Sciences, 2014-07-14)
    The coupling between the stratosphere and the troposphere following two major stratospheric sudden warmings is studied in the Canadian Middle Atmosphere Model using a nudging technique by which the zonal mean evolution of ...

  • The response of the lower stratosphere to zonally symmetric thermal and mechanical forcing. 

    Ming, Alison; Hitchcock, Adam Peter; Haynes, Peter Howard (American Meteorological SocietyJournal of the Atmospheric Sciences, 2016-04-15)
    The response of the atmosphere to zonally symmetric applied heating and mechanical forcing is considered, allowing for the fact that the response may include a change in the wave force (or ‘wave drag’). A scaling argument ...

  • Zonally symmetric adjustment in the presence of artificial relaxation 

    Hitchcock, Adam Peter; Haynes, Peter Howard (American Meteorological SocietyJournal of the Atmospheric Sciences, 2014-06-15)
    Numerical experiments, presented in a companion paper, have been performed in which the zonal mean state of the stratosphere in a comprehensive, stratosphere-resolving, general circulation model is strongly relaxed (or ...
