RISEddy Velocities in the Planetary Boundary Layer as Obtained from Tetroon Flights at Idaho Falls
Publisher: American Meteorological Society
Abstract: Tetroon flights made at the National Reactor Testing Station, Idaho Falls, during the past few years have provided values of eddy velocity within the planetary boundary layer. In this desert-like terrain the root mean ...
A Lagrangian Study of Helical Circulations in the Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: During July 1966, nearly 100 tetroon flights were made at the National Reactor Testing Station (NRTS), Idaho Falls, with the primary purpose of verifying the existence of longitudinal roll-vortices, or helices, in the ...
Tetroon Trajectories in the Los Angeles Basin Defining the Source of Air Reaching the San Bernardino-Riverside Area in Late Afternoon
Publisher: American Meteorological Society
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 ...
Comparison of the Vertical Motions of Paired Tetroon Flights
Publisher: American Meteorological Society
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. ...
Relative Diffusion within the Los Angeles Basin as Estimated from Tetroon Triads
Publisher: American Meteorological Society
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 ...
Tetroon Trajectories in an Urban Atmosphere
Publisher: American Meteorological Society
Abstract: Tetroon flights at heights near 300 m within the Los Angeles Basin illustrate the useful results to be derived from the use of Lagrangian probes in an urban environment. The tetroon trajectories depict air-flow reversals ...
Urban Influence on Nighttime Airflow Estimated from Tetroon Flights
Publisher: American Meteorological Society
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 ...
Three-Dimensional Air Trajectories Determined from Tetroon Flights in the Planetary Boundary Layer of the Los Angeles Basin
Publisher: American Meteorological Society
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 ...
Urban Influence on a Strong Daytime Air Flow as Determined from Tetroon Flights
Publisher: American Meteorological Society
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 ...
