Baroclinic instability of an idealized model of the polar night jet
Abstract The zonal current u ( z ), considered by Murray (1960, Section 4), as a model for the polar night jet in the lower stratosphere, has no shear in the model troposphere, and constant vertical shear u z in the stratosphere, u being a continuous function of z . The Richardson number is large. I...
