LARGE-AMPLITUDE GRAVITY-WAVE BREAKING OVER THE GREENLAND LEE AND THE SUBSEQUENT FORMATION OF DOWNSTREAM SYNOPTIC-SCALE TROPOPAUSE FOLDING AND STRATOSPHERIC-TROPOSPHERIC EXCHANGE

 Large- amplitude internal gravity waves may be generated as a consequence of stably stratified air that is forced to rise over topography.The present extended abstract describes an extreme topographic flow event that occurred in the eastern lee of Greenland.The severity of this event warranted its simulation and diagnosis with the NCAR/Penn State MM5 multi-scale prediction system and is presented here.
