1. There are two types of Rossby waves, barotropic and baroclinic. 2. Barotropic Rossby waves have the highest speeds and do not vary vertically.3. Absolute transports including barotropic circulation are monitored using precision bottom pressure gauges. 4. One common class of barotropic model used in astrophysics is a polytropic fluid. 5. Typically, the barotropic assumption is not very realistic. 6. Hence, the motions of a rotating barotropic air mass is strongly constrained. 7. In this type of atmosphere, Euler equations reduces into the barotropic vorticity equation. 8. Geostrophic flow may be either barotropic or baroclinic. 9. Barotropic Rossby waves do not vary in the vertical, and have the fastest propagation speeds.10. A "'barotropic flow "'is a generalization of a barotropic atmosphere.
