Description
Hurricane spawned tornadoes are most frequent at the time when hurricanes initially cross land and undergo rapid filling. This paper presents data composite information on all available rawinsonde and pibal reports surrounding this type of tornado genesis in the United States and Japan.

Description
A dynamical forecast model is applied to study the moisture variation in the planetary boundary layer under the chosen synoptic condition. The observed 12-hour moisture patterns are compared with the forecast patterns.

Description
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.

Description
The results of a detailed analysis of 159 tornado proximity rawinsonde soundings are considered in Part I of this study. An extensive discussion of tornado features and a hypothesized physical model of tornado genesis is presented in Part II of this paper.

Description
Data acquired during the 1972 Venezuelan International Meteorological and Hydrological Experiment is used to study the thermodynamic structure of the cumulus sub-cloud layer: its time dependence, and transformation by precipitation. A close relationship between lifting condensation level (LCL) and cloud base, and between LCL and the transition layer is found.

Description
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.

Description
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...

Description
Visible and infrared image data from the scanning radiometer on the NOAA-2 and NOAA-3 satellites are received by a VHF "APT" Station at Colorado State University. In addition to producing the regular hard-copy photographs, the taped signal is specially processed by electronic means, converted from analog to digital form and further processed in the computer. Details of the processing steps and equipment will be described and the meteorological application...

Description
Evidence has accumulated over the last twenty years that in some clouds the concentration of ice crystals may be a factor of four or five orders of magnitude greater than the concentration of observed ice nuclei apparently available to the cloud.

Description
For several days at the end of January and the beginning of February 1972, the components of short-wave radiation were measured over a snowfield in a valley of the Rocky Mountains at a height of 2700 m above sea level.
