Geostrophic Wave Circulations
Yong Zhu
1) The unique approach for solving the nonlinear primitive equation analytically.2) New three-dimensional perturbations in the divergent atmosphere, which possess the geostrophic property much better than that of non-divergent Rossby waves.
3) Explanations for the geographic distributions of orographic and thermal stationary waves and their seasonal changes at different latitudes, based on the global balances of momentum and heat under the effects of nonlinear eddy transport.
4) Reproduction of the zonal mean circulation fields in terms of the nonlinear transport processes.
5) Theoretical demonstrations of the geographic distributions of low and middle frequency variabilities and their seasonal changes according to the long-term balances and local feedback.
6) Realistic illustrations of the onset, development and decay of blocking systems in the nonlinear processes of wave-wave interactions.
7) Development of synoptic disturbances in the geostrophic wave which manifests the realistic growth rate compared with the previous disturbance models including the Eady waves.
8) Realistic demonstration of the warm pools in the stratosphere according to the nonlinear theory of planetary wave interaction introduced.
9) Realistic demonstration of the stratospheric sudden warmings according to the new theory of thermally forced nonlinear baroclinic instability in the planetary wave circulations.
10) Three-dimentional group velocity and ray-tracing theory for anisotrophic atmospheric waves.
