Not sure where to begin in deconstruction, but it seems that the
following statement:
"Weather has alpha-stable distribution. This means varince is
infinite, at least in theory."
Is demonstrably false, since at some value of significant enough
atmospheric excitation there would cease to be an atmosphere due to
the gasses achieving escape velocity, as the most obvious example of
some sort of limitation on the system.
Hm.. another example of system governed by stable distribution is time
series of stock prices. Economists are arguing in similar way, but are
unable to come with anything better. Instead, they stick to gaussian and
lognormal distributions (which is valid for short time interval samples
from series).
My guess is that a more valid model of weather is that it is variable
within bounds set by climate, and climate within bounds set by
insolation, albedo, gas composition (I doubt we're about to get a
methane atmosphere any time soon, FE), etc.
You are describing almost the same model. But you sidestepped question
of distribution of - say - temperature. What distribution will you get
for temperature in your model?
IOW, it's actually in dynamic equilibrium locally, but it's gross
equilibrium is static in a relatively small spectrum, absent some
major external force.
For something more in-line with the expertise of this group, some
examination of the (awful IMNSHO) actual code used at the CRU is in order:

Yes, they can't write readable code and are unable to use DBMSs. But
what did you expect? They are scientists, not programmers.
