Low-Frequency Atmospheric Acoustic Energy Associated with Vortices Produced by Thunderstorms
@article{Bedard2005LowFrequencyAA, title={Low-Frequency Atmospheric Acoustic Energy Associated with Vortices Produced by Thunderstorms}, author={A. Bedard}, journal={Monthly Weather Review}, year={2005}, volume={133}, pages={241-263} }
An infrasonic observatory collocated with the Colorado State University CHILL radar during the summer of 1995 permitted unique comparisons between severe storm kinematics and detected acoustic energy at subaudible frequencies near 1 Hz. Radar observations of a velocity couplet aloft (evolving into a tornado) showed a circulation maximum descending for about 30 min while moving to the east. The detected infrasound followed the trend of these observations. A model of sound radiated from vortex… CONTINUE READING
