Say, there was a line of thunderstorms, and from the clouds one could hear a
continual monotonous roar as if a jet plane or two were hanging stationary
inside the clouds, for several minutes. Is this the sound of wind shear?

No -- it is the sound of a tornado! You can verify by taking an old B&W
TV set, tuning to Channel 2, reducing the brightness till the picture
goes away. The lightning will show up as lines of hash. A tornado emits
so much RF that it will turn the screen white, if it is within about 15
miles of the set.

Needless to say, use only the antenna, NOT a cable hookup!
