The evolution and enhancement of occluded frontal circulation in upper-level westerly jet and lower-level southerly jet are discussed by using a dry primitive equation model.
The design of a total energy conserving semi-implicit scheme for the multiple-level baroclinic primitive equation has remained an unsolved problem for a long time.
By using of the 5-level primitive equation model, the short range evolution of the subtropical ridge and the subtropical high structure for 23-26 June 1980 was experimented.
