Below cloud base, the air is very disturbed and can be extremely
turbulent.

Thanks for the reply, Jack.

.... this used to be an ongoing discussion when STC used to provide the
military charts : what was significant when forecasting for a wide
variety of a/c? A consequence of the successive mergers between military
formations (the most significant being between Transport/Air Support and
Strike) was that we had 'one size fits all' output - it never works, and
you are going through it again with the merger of civil and military
output. As Jack writes, fast jets etc., whistle through these phenomena
with hardly an impact - the larger/slower types (which are used on
low-level flights for extended periods, e.g. C-130 on para-drops or
battlefield supply) would be interested in turbulence from whatever
cause. The w/e gliding schools/fixed wing 'familiarisation' flights
would also be wary of turbulence from whatever cause.

Martin.
