The purpose of this paper is to analyse the thermo-dynamical response of the stratosphere-troposphere system to the solar corpuscular and electromagnetic forcing during Solar Proton Event in January 2005 (SPE-05). Cross-correlation analysis of the zonal wind and temperature reveals a warming of subtropics and mid-latitudes (with a time delay of about 5 days) and cooling of the polar cap with time lag of 20-30 days. The zonal wind response manifests itself as a strong and almost instantaneous acceleration of the vortex core and delayed westerlies, deceleration at its polar and equatorial edges. The temperature response equatorward of 500N are most probably related to the increased solar ultra-violet (UV) radiation, whose effect can not be separated by the cross-correlation technique from those of the corpuscular heating. Multi-factorial and multivariate statistical analysis of the zonal wind before and after the SPE-05 confirms the leading role of the solar short time variability. Moreover, it turns out that the vertical propagation of planetary waves is strongly influenced by bursts in solar UV and corpuscular radiation. Comparison of the effectiveness of solar and wave forcing shows that solar impact is dominant factor influencing temperature and zonal wind in the period of preparation of final stratospheric warming in 19 March 2005.
