Oceanographic and Atmospheric Processes

The linearized response of the atmosphere to thermal and orographic stationary wave forcing is examined with a high resolution (1km vertical resolution, 1.5° latitude resolution) primitive equation model. It is found that the response to thermal forcing (but not orographic forcing) is sensitive to small changes in the basic distribution of wind and temperature. This suggests that anomalies in stationary waves can occur even without changes in forcing.
