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.

Two well documented cases of tradewind disturbances are studied. One disturbance developed into Hurricane Carla (1961) while the other failed to intensify. Initially the two cases appeared to be very similar but on closer inspection the flow patterns in which the disturbances were embedded proved to have significant differences. This paper describes these differences.

Characterizes the static environment of middle and upper tropospheric clouds as deduced from rawinsonde data from 24 locations in the contiguous U.S. for 1977.

The structure of hail-producing and no hail-producing atmosphere is studied by examining rawinsondes launched at New Raymer, Colorado, in the summer of 1967. It is found through examination of mean soundings and the convective condensation level and level of free convection that an ample low-level moisture supply is important for hailstorms to form.

Meridional fluxes of angular momentum and kinetic energy values have been computed for the month of January 1964 for five longitudinal sections of the Northern Hemisphere.
