Climatologically, the winter months show a peak in gale frequency.
As far as I know the autumn equinox does not show any peak, but I saw
some study (can't remember where now) which showed an increase in
gales near the spring equinox.
This figures as north-south temperature gradient is at a max then due
to Arctic ice.
Warming mid lats in spring enable any instabilty in the westerly flow
to concentrate the temp. gradient and so amplify the disturbance.
