Abstract: The hydrodynamic instability characteristics of planetary zonal flows are investigated through use of a quasi-geostrophic numerical model of high spatial resolution. An initial-value technique is employed to obtain solutions ...

Abstract: The numerical model of Part I is used in certain experiments designed to reveal special instability effects caused by the vertical walls which specify the lateral boundary conditions at the northern and southern boundaries ...

Abstract: Data from eight water vapor soundings made with the dew-point hygrometer instrument at McMurdo Sound, Antarctica, are presented. These data are compared with various north temperate latitude data. The soundings are too ...
