I can see a 20-odd year cycle in there too but the 50-odd is not
obvious.

What 20-year cycle can you see then, Michael? I can't see anything of
that kind, the only tendency I see is a lack of years with less than 60
hot days in the last decade and a half.

It is only very roughly 20 years.

By the way bear in mind interference patterns where cycles overlap. Like
the nodes in accoustics. With the ideal conditions two opposite nodes
will sometimes cancel each other out, sometimes work to increase the
wave height or trough depth.

(Which explains the missing snow for around 2001.)

There does seem to be a solar max min cycle

As in sunspots? I'm familiar with the theories that they affect the
weather, I thought the sunspot cycle was 11 years?

linked to the period of
lunar nodes. (Lunar nodes are periods when the combination of the 5
degree difference of the lunar orbit combines with the eccliptic to
produce declinations of 23 1/2 degrees plus or minus 5 degrees.*


So are you saying that the declination of the moon (which I know can be
more than 23 1/2, up to about 29 north and south), combines with the
sunspot cycle to produce hot/cold weather? If so, how? (And what type
of weather do various alignments produce?)
