Also has anyone been able to climb up the sunny side of a cumulus

I did this twice on different occasions. It isn't always the sunny side you
can climb, but the upwind one.

I also did this for the first time last year near Gransden Lodge at the
end of September. There was a fairly strong breeze at flying height and
good streeting. I noticed a short (1 km) spur running off one street at
right angles so had a play. I was able to get 1-200 feet up the windward
side of the spur for about 4 beats along it. I think it was transient
sheer wave because when I looked at the trace afterwards the spur was
being steadily blown downwind the whole time.
