A DYNAMICAL STUDY OF THE 1958-59 STRATOSPHERIC POLAR VORTEX

The circulation of the stratosphere and its relation to the troposphere is presented for the six-month period October, 1958 to March, 1959. The study is based mainly on circumpolar analyses at five-day intervals at the 500-mb, 100-mb and 25-mb levels, supported by numerous space and time sections. F...

Description
Summary:The circulation of the stratosphere and its relation to the troposphere is presented for the six-month period October, 1958 to March, 1959. The study is based mainly on circumpolar analyses at five-day intervals at the 500-mb, 100-mb and 25-mb levels, supported by numerous space and time sections. FourierANALYSIS OF THE CIRCUMPOLAR CHARTS IS USED TO COMPUTE ENERGIES AND ENERGY EXCHANGES AFTER THE MANNER OF Lorenz (Tellus, 7:157-167, 1955) and unstable wave characteristics following the linear theory of Fleagle (Quart. J. R. Meteor. Soc., 83:1-20, 1957). The polar-night middle stratosphere is found to be baroclinically unstable in mid-winter, otherwise the energy exchanges appear to be ascribable to forced perturbations. (Author)
