Monsoon dynamics: GCM results on Orography Thermal heating vs.Mechanical forcing (II) Artificially separate the thermal and mechanical forcings of Tibet Plateau Experiment design: prescribed,seasonally varying SST and sea ice orographic setting-changing prescribed surface elevations no-sensible heat experiment-the surface energy balance was kept unchanged,but the surface sensible heat released at the elevation above 500m was not allowed to heat the atmosphere.
