Abstract :
Sound portrayal techniques used in studies of speech and noise reveal the structure of atmospheric disturbances well known to long-wave radio and ocean-cable engineers as "whistlers," "swishes," and "tweeks." It is suggested that renewed investigation of these effects, using modern analyzing tools, might yield information of considerable scientific interest.
