Abstract: The atmospheric sciences, along with other disciplines, are today contemplating strong competition for resources, exciting scientific challenges, and the need to assess opportunities and priorities. This review is intended ...

Abstract: The quasi-geostrophic theory leads to a single nonlinear partial differential equation for a streamfunction giving geostrophic velocity fields presumed to resemble the synoptic scales of atmospheric motion. This article ...

Abstract: Properties of nonlinear quasi-geostrophic flow in unforced and in thermally-forced, dissipative modes are compared. The article is based on the philosophy that precise versions of the important problems of predictability ...

Abstract: Aperiodic solutions to spectrally truncated models based on the vorticity equation are considered for the case of a zonal flow interacting nonlinearly with two other components both having the same zonal wavenumber. It is ...

Abstract: The variance spectrum of velocities in a non-homogeneous, compressible fluid does not represent the wave-number distribution of kinetic energy, as it does in incompressible, homogeneous (constant density) fluids. Use of a ...

Abstract: An analytical model of the globally averaged surface temperature response to changes in radiative forcing induced by greenhouse gases is developed from a time-dependent version of the global energy budget. The model clarifies ...

Abstract: The problems and advantages of the bolometric method of measuring surface temperature from an airplane are discussed. It is shown that the airborne bolometer measures a weighted area-mean temperature which is a function ...

Abstract: A new Lagrangian method of determining energy conversion rates for individual cyclones is developed and applied to the rapidly deepening storm of Nov. 29?30, 1963. It is shown that 12-hr average conversion rates can be ...

Abstract: A truncated spectral model of the forced, dissipative, barotropic vorticity equation on a cyclic ?-plane is examined for multiple stationary and periodic solutions. External forcing on one scale of the motion provides a ...
