Doppler effect
The Doppler Affect
Doppler Shift. It occurs in electromagnetic radiation too, though is really only significant at extremely high speeds such as the recession-rate of galaxies.
Air in a tornado travels upward rapidly. In some cases it takes objects with it.
Air in a tornado move upward rapidly and can carry objects with it.
Yes - on density but not frequency. Sound (of any frequency) travels much more rapidly through water, for example, than through air.
It's a large horn therefore it makes a low pitched sound; large objects do not vibrate as rapidly as smaller objects do.

a frequency higher then the original frequency...
By slowly vibrating objects and rapidly vibrating objects respectively.

A frequency higher than the original frequency.
In addition to rotating, air in a tornado flows upward fairly rapidly. Often, this is enough to lift objects of the ground, sometimes very large objects.

"Waters that slowly/rapidly drift" "Swerve/shimmer and shift"

The black absorbs radiation and reflects little of it. This causes black objects to get warm quickly. White reflects much of the radiation that hits it, and it doesn't warm as rapidly. This is the cause for black objects getting hot quickly in the sun, and white objects to warm less rapidly.
Frequency agility is the changing radar frequency rapidly and continuously to minimize jamming effect or enhance the target resolution and hit per scan. where as frequency diversity is a method to couple two radar transmitters to a single antenna simultenously to increase the range of radar in terms of coverage.
