| 内容記述 | The Eliassen-Palm (EP) cross sections for the model are discussed. EP cross sections conveniently display the principal eddy fluxes of heat, momentum, and quasi-geostrophic potential vorticity on one diagram. The EP diagnostics are used to follow the evolution of the mean flow through into the second stage of the model warming, which includes the reversal of the polar westerlies and which appears to have more in common with observed warmings. The transformed Eulerian-mean equations presented by Andrews and McIntyre (1976, 1978) provide the basis for an investigation in which an especially clear picture of the warming dynamics is obtained. In the second stage of the model warming, the decelerating torque per unit mass is large throughout a deep layer in the middle atmosphere, spanning several scale heights. |
