Abstract

A first evidence of severe turbulence in the lower stratosphere during easterly tropospheric flow over Greenland is presented A numerical simulation shows the turbulence to be associated with gravity wave breaking and that simulating with a horizontal resolution of 3 km gives substantially greater and more realistic turbulence than at a 9 km horizontal resolution It is concluded that realtime simulations at high resolutions would improve aviation forecasts As the atmospheric flow impinges on SouthGreenland a barrier jet a reverse tip jet and amplified mountain waves with secondary wave breaking are generated at the same time
