Some aspects of the effects of sensible heating on the development of summer weather systems over the Tibetan Plateau.

It was found that sensible heating could cause local intensification of vortices over high elevations and sometimes act in combination with topography to block intrusions of cold air. Sensible heating can play an important role, when it is combined with topography and the proper synoptic situation. Sensible heating had a greater impact over higher elevations, areas with strong cold advection, and areas under the upper-tropospheric jet stream. Sensible heating tends to destabilize an air column, permitting downward transfer of W momentum in the vicinity of the jet stream and causing an increase in cyclonic vorticity in the lower troposphere N of the upper-level jet. -from Authors
