Abstract: Laboratory experiments with finite-amplitude baroclinic waves arising from instability of a two-layer f-plane shear flow are reported. They show that as the system becomes more and more supercritical, as measured by ...

Abstract: Simple expressions are presented for the corrections to the classic Ekman pumping law We = ?·curl(τ0/f) due to nonlinear advection effects in the surface boundary layer. These involve products of the surface Reynolds stress, ...

Abstract: Limit-cycle type oscillations of the amplitude of a baroclinic wave field, which has grown by instability on a background zonal flow, have been observed experimentally in a rotating cylinder containing two immiscible fluid ...

Abstract: This paper discusses the nature of quasi-geostrophic ?-plane flow over an idealized set of ridges with height h=F(y/Ly) cosx/Lx. When the mountains are highly anisotropic, with scale factor ratio Lx/Ly?1, the asymptotically ...

Abstract: Airbone Doppler lidar wind measurements were obtained in the lee of Mount Shasta in northern California on 28 August 1984. These data consist of line of sight wind vectors at flight level (3000 m) and along planes tilted ...

Abstract: This paper describes observation of the East African low-level jet stream obtained during June and July 1977 with a long-range research aircraft. We present results based on the real-time display of data on board the ...
