A relationship is established between relative geostrophic vorticity on an isobaric surface and the Laplacian of the underlying layer-mean temperature. This relationship is used to investigate the distribution of vorticity and baroclinicity in a jet-stream model which is constantly recurrent in the winter troposphere.

From this study it appears that until accurate observations of the state of the atmospheric mesostructure are available, no unique correlation between Ri and clear air turbulence (CAT) should be expect·ed to exist.

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

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.

In July 1990, the Department of Atmospheric Science at Colorado State University (CSU) received a grant from the National Oceanic and Atmospheric Administration (NOAA) to deploy Surface Radiation Budget (SRB) measurement stations in a region of the equatorial western Pacific in order to collect data for a pilot study of the radiation budget.

Supercooled liquid water flux over the Tushar Mountains was estimated from three hour averages of the radiometer and rawinsonde observations. The amount of liquid water represented by this flux over the two-month project was 17,000 acre feet, or about 45 percent of the total annual runoff in the Beaver River watershed.

This paper presents a diagnostic study of two models proposed by Betts (1973a). The first was a model for a well-mixed sub-cloud layer capped by a more stable transition layer. The downward heat flux at the base of this transition layer is here estimated from the thermal structure of the layer to be 15-25% of the surface sensible heat flux. The second model was a model for a two layer lapse-rate structure for the cumulus layer. A sensitivity analysis...
