Abstract: Tetroon flights across the northern California coast indicate the influence of a laterally extensive and fairly abrupt 100-m change in terrain height near the shoreline on the three-dimensional low-level air flow. Beneath ...

Abstract: Direct beam hourly solar radiation values, measured near solar noon under clear skies, were used to show the decrease in radiation in the United States caused by the debris cloud from the El Chichon volcanic eruption of ...

Abstract: Tetroon trajectories within the Los Angeles Basin in the autumn of 1973 show that, on non-stagnation days, air located in the Los Angeles area in the morning can pass over the Puente Hills and reach the San Bernardino-Riverside ...

Abstract: Pairs of constant volume balloons (tetroons) released ?1 min apart from the same site at Haswell, Colo., and continuously tracked by two M-33 radars, are used to estimate the mutual consistency of tetroon vertical motions. ...

Abstract: The Los Angeles Reactive Pollutant Project (LARPP) in the autumn of 1973 involved helicopter sampling of a volume of air ?tagged? by means of three constant volume balloons (tetroons) released simultaneously from a point ...

Abstract: Constant-volume balloon (tetroon) flights tracked by radar across Columbus, Ohio, in March 1969, illustrate the effect of a city on the nighttime airflow at heights of 100?200 m. On the average, the urban influence on wind ...

Abstract: Between 9 September and 2 October 1969, 105 constant-volume balloons (tetroons) were released from various sites in the Los Angeles Basin for the purpose of obtaining three-dimensional air trajectories in the planetary ...

Abstract: Tetroon flights across Oklahoma City indicate the influence of an isolated urban area on the horizontal and vertical air velocity at heights near 400 m in relatively strong (13 m sec?1) daytime flow. The Lagrangian ...
