Abstract: A field observation program was conducted at El Mirage, Calif., to investigate some aspects of the interaction between dust devils and their environment. The outputs of sensors designed to measure vertical vorticity were ...

Abstract: An experiment has been constructed which yields a vortex flow similar in many respects to atmospheric dust devils. Measurements were made of air velocity and temperature in the vortex core. These results were compared with ...

Abstract: An investigation of the dominant horizontal scale of motion in free convection, using data from GATE, principally from the NOAA acoustic sounder, is described. The horizontal scale was seen to vary from two times the depth ...

Abstract: Measurements during periods of atmospheric free convection have been made using acoustic echo sounders and conventional wind sensors on a meteorological tower. Comparison of data from the two instrument systems shows good ...
