RE Weather Forcasting

Thanks, sounds like the book I was thinking of. I bought a
copy so we shall see.

Dave was kind enough to reply:

Bernard Moitessier in his book A Sea Vagabond's World says "I
heartily recommend Alan Watts' little book Instant Weather
Forecasting, which taught me how to predict weather changes in
minutes. Its terrific, all you do is compare the lower, or surface
(cumulus) wind direction with the upper, or high altitude (cirrus)
wind direction and apply the crosswind rule. " There are 24 coloured
photos of clouds and a full explaination of the theory.
Hope this helps. Dave Limbrick
