31. The vorticity equation for a frictionless atmosphere may be written using pressure as the vertical coordinate: 32. An equatorward heat flux is induced, decreasing potential vorticity and pressure anomalies and yielding cyclolysis. 33. More precisely, the vorticity is a pseudovector curl ( rotational ) of the flow velocity vector. 34. He also investigated how western boundary currents, such as the Gulf Stream, dissipated planetary vorticity . 35. The volume integration of certain flow quantities, such as vorticity moments, is related to forces. 36. The derivation of the \ omega equation is based on the vorticity equation and the thermodynamic equation. 37. Note that the fractions have odd denominators, which follows from the even vorticity of composite fermions. 38. They found that changes in potential vorticity at the tropopause can cause changes in the wind field. 39. Specifically, different schemes have different methods of parametrizing the potential vorticity which results in different tracks. 40. The discontinuity in the tangential velocity means that the flow has infinite vorticity on a vortex sheet.
