Close...it's water vaporizing in the low pressure air just behind the high pressure, compressed wave.
It's an effect that happens more with some explosives than it does with others. Many explosives don't produce a pressure wave of long enough duration for a noticeable effect in low humidity, especially bombs that bury them selves. Other bombs with long burn durations, like fuel air bombs produce lovely pressure waves. Humidity also has a big effect. Bombs in 'Nam show nice vapor waves whilst bombs in Desert Storm don't.
In summery...sure, you will see thins with some bombs in some conditions in the BoB, for instance if it is slightly misty and the bomb is not buried, but certainly not all the time.
not worth adding IMHO.
