Extratropical eddy distributions in four months typical of the four seasons are treated in terms of temporal mean and temporal r.m.s. values of the geostrophic relative vorticity.
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 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.
Data from an experiment to measure the upward and downward components of solar radiation from aircraft during the Barbados Oceanographic and Meteorological Experiment (BOMEX) have been analyzed in the present study.
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.
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.
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.
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.
Atmospheric structure derived from satellite, multi-channel radiance data is used to calculate zonally-averaged vertical motions in the wintertime stratosphere of both hemispheres.
