The influence of stratospheric conditions on the climate has recently become widely accepted. Coupling in the stratosphere-troposphere system causes large amplitude dynamical activity occurring in the middle atmosphere to have significant consequences on the troposphere's equilibrium and flow. Sudden stratospheric warmings are the clearest and strongest manifestation of such activity. This study focuses on the impact of these events on the variability of the middle atmosphere and on estimations of temperature trends. Another objective of our work is to acquire a better understanding of the evolution of a stratospheric warming, from the state of the atmosphere that initiates such an event to its consequences on both the middle atmosphere and...
