The divergence of net radiation in a tropical atmosphere with cirrus clouds has been examined in terms of two bulk radiative properties of the cloud: shortwave thickness and broad-band infrared emissivity.

A simple formalism for the diagnostic use of the feedback and static control portions of the theory is presented. The relation of the subgrid scale flux forms and the detrainment forms of the large-scale heat and moisture budgets is also discussed.

The results indicate that the presence of extensive low-level decoupled flow does indeed cause part of the orographic lift of the mountain barrier to be experienced upstream of the barrier. This changes the location of condensate production which in turn shifts precipitation upstream.

The present study is designed to provide both a method whereby the details of the nonlinear exchange process which occurs in the atmosphere may be considered in a simplified form, and also to indicate from some calculations the complexity of those exchanges.

A general numerical integration formula is presented which generates many of the commonly used one-dimensional finite-difference schemes.

Theoretical and observational studies are carried out to evaluate the use of cloud near-infrared spectral reflectance to determine cloud droplet size.

A generalization of the two-dimensional spectral forecast equations is suggested, whereby the atmospheric flow field in horizontal and vertical directions is represented in terms of orthogonal functions, which are eigenfunctions of certain differential operators in the three-dimensional equations. The technique is applied to the quasi-geostrophic potential vorticity equation.
