Hurricanes and solar radiation

It would appear the weather in the UK turns murky in October/November
every year. I can't think why I had forgotten this as it is something
that occurs almost ever year and is singularly depressing therefore not
easily ignored. It is also fabled in weather lore and prose. I have
noticed too that it clears with a bang of some sort. Why I didn't look
for the coincidence of earthquakes I can't explain. But this does seem
to hold true too! The question is, is it true that it produces major
earthquakes or can it also let off steam with different types of quakes?
Why are the tropical and subtropical storms that also derive their power
from such runs of the phases not present?

Many assert "tropical/subtropical storms" are nature's way of
Transferring/equalizing heat over vast areas of the world. The "Energy
Transfer Budget" of tropical/subtropical storms is tremendous.

If my limited understanding is correct, tropical storms occur when water
temps exceed 80 F. Further the intensity of these storms is directly
related to water temp. The higher the water temp the more intense a
storm. Further there is a direct time/water temp relationship that
determines storm size, intensity, & strength.

Why on earth are you reading my stuff?

You will find yourself branded if you are not careful.

About hurricanes:
The first thing to note is they appear to have a seasonal intensity just
like the sub polar cyclones that move from Canada’s rich fishing
grounds, through Iceland’s to Scotland and Norway. I wonder what the
fishing is like after the subtropical storms.

Purists can use obvious dissimilarities in the behaviour of hurricanes
to prove that the much vaunted Coriolis Effect need not apply to their
northern cousins.

Insolation:

I got most of the following from the Encyclopedia Britannica so any
errors are only my oversight or classical bloopers. (It goes without
saying that my slant is the corrected view.)

The earth receives heat from the sun (insolation) in the wave band 0.39
to 0.76 micrometers. Earth gives off longwave radiation of 4 to 30
micrometers.

At 6000 degrees Kelvin (*K) apparently, the sun has a shortwave heat
spectrum. This is due to a bloke called Planck who decreed that earth
has a longwave spectrum of 250 to 300 *K. (Astute followers of my drivel
will note how carefully I let God sort out who gets the real credit by
not mentioning God at all. (Not even in passing.))

A fraction of insolation directly warms the earth’s atmosphere. Where
cloud is absent most of the heat gets through but 80% is reflected off
the earth. That which falls on snow has a 95% return rate and that
hitting “rich dark soils” 10%. At least that is my understanding of the
term albedo. I stand to be corrected. (I’m just trying to keep it
simple.)

In water the heat penetrates several hundred metres and is distributed
equally through this depth as the insolation causes less temperature
change than it does over land. (One wonders what controls are used to
rule out the other source of heat evolution.)

Water and carbon dioxide absorb long wave radiation. Clouds with a 2.5
gram/cubic metre water content, completely absorbs all solar radiation
in 12 metres. Funny how it goes so deep so equally in sea water. (Anyone
know how thick the cloud is over the track an hurricane is going to
follow?)
