Dr. Chen will study the forcing of stationary waves in both             Northern and Southern hemispheres using a steady state model. The               model employs a lower boundary condition (LBC) which                            incorporates what is probably the most important nonlinear                      effect, namely, allowing flow to go around as well as over the                  orography.  The specific objectives are: 1. to further explore                  the dynamics and the responses of the planetary waves by the more               complete LBC (wave.coupled LBC) in the linear model used by Chen                and Trenberth (1988a,b) and the issue of flow going "around" or                 "over" a mountain from both theoretical and computational point                 of views; 2. to elaborate on the interpretation of the wintertime               Northern Hemisphere (NH) subtropical jet streams by momentum                    budget studies and the theory relating the "rotational and                      divergent geopotentials and planetary vorticity advection                       potential" in a linear balance system (Trenberth and Chen, 1988);               3. to simulate the observed planetary waves in the NH summertime                and Southern Hemisphere wintertime, and to explore the reasons                  for the observed differences in planetary waves between the two                 hemispheres in wintertime; 4. to investigate the kinematic                      destabilizing effect of the Himalayas on the abrupt onset of the                southwest.Asian monsoon.
