Abstract: Wind data from the central five stations of the 1961 Weather Bureau boundary-layer-jet research pibal line are space-averaged as point data. In this form the information is compatible with other boundary-layer wind analyses ...

Abstract: For the first time in meteorological history the broad aspects of the southerly low-level jet over the Western Plains have been studied in fine detail both in time and space. This was accomplished in the spring of 1961 by ...

Abstract: Drag coefficients were determined for a 152-cm (60-inch) tetrahedral Mylar plastic balloon in free flight as functions of Reynolds numbers ranging from 104 to 3.3 ? 105. Vertical relative air speeds ranged from 9 to 270 ...

Abstract: A composite distribution of tangential and upward components of air flow is determined by tracing particles of debris and cloud tag movements in scaled movies of a tornado. The greatest tangential speed measured is 170 ...

Abstract: The three-dimensional pressure field of the Dallas tornado, April 2, 1957, is integrated from a distribution of observed tangential wind speeds. A total pressure drop of 60 mb. is computed at ground level at the axis. ...

Abstract: Fifty-five constant volume balloons (tetroons) were released in the fall of 1971 at Oklahoma City, Okla., and were ballasted to float at about 300 m over the city (elevation 400 m MSL) to trace local air currents. Twenty ...

Abstract: A slow but steady increase in the use of tetroons for tracing atmospheric air trajectories has prompted the development of an automatic method for calculating accurate tetroon inflation factors to float tetroons at desired ...

Abstract: A model has been developed for predicting diurnal height changes of quasi-constant-density Mylar tetroons resulting from the complex interaction between thermally induced density changes of the tetroon and height-dependent ...

Abstract: From the records obtained during the Weather Bureau Artificial Cloud Nucleation Project carried out in western Washington State during the winters of 1952?53 and 1953?54, it is possible to study the nature of some of the ...
