That's pretty unlikely. What's the explanation for 1982, 1983, 1984,
1986, 1987, 1993, and 1994 having less intense hurricanes than 1980 or
1991?
Debatable. Andrew was the strongest of the two years, but the next two
strongest ones, Claudette (115 kt maximum) and Bob (100 kt) were both
1991 hurricanes. Bonnie and Charley (both 95 kts in 1992) were 4th and
5th, Grace (1991-85 kts) was 6th. Not much difference there, if any.
8
storms reached tropical storm status (one of them unnamed) in 1991 and
6
did in 1992 (with another subtropical storm in the list).
And your plan for moving all that heat from the tropics northward is?
Little, if any, of Mt. St. Helens output was still in the atmosphere by
the main part of hurricane season. It was a low sulfur eruption and
the
blast was horizontal, so not even much of the tephra got into the
stratosphere, where residence times are longer.
Ash typically washes out quickly. It's not important for climate. SO2
is the climaticly important output, mixing with H2O to form sulfuric
acid aerosols. I'll summarize the output, but there's no way that the
aerosol distribution can be summarized. I recall that El Chichon
quickly dispersed into a homogeneous band from the equator and 30 N,
before slowly expanding northward, reaching Ann Arbor, MI in early
October.
Pinatubo (June 1991) was a VEI 6 eruption, putting out 10 cubic km of
tephra and 20 million tons of SO2. Mt. St. Helens (May 1980) was VEI
5,
so an order of magnitude less explosive, with little SO2. El Chichon
(April 1982) was also VEI 5, but put out 10 times as much SO2.
Pinatubo
had the biggest effect on global temperatures and El Chichon was
ssecond, with most of its effect in the northern hemsisphere.

Thanks for the information, for it leaves me with the impression that
past volcanic activity did not affect by much the hurricane activities.
I was hoping to use volcanic ash as a sort of modelling to the
application of Aluminium Sequin in orbit to cool Earth. But the data
suggests volcanic ash is no good for a modelling tool.
I would be remotely interested whether the most fierce volcanoes such
as Krakatoa ?? year ?? whether they preempted the formation of all
hurricanes when they exploded. But I guess we have no means of finding
out whether any hurricanes formed after Krakatoa exploded and no
"fossil imprint of hurricanes in the past". Perhaps there is a budding
new science or technique that can tell us whether in the year of
Krakatoa or succeeding years after Krakatoa as to whether the hurricane
activities were stopped for several years. Kind of hard to leave a
fossil imprint when the activity is mainly water and air activity. Is
there a living creature that is associated with hurricanes and can thus
offer some clue as to the number and frequency of hurricanes in the
history before humanity recorded hurricanes?
I guess the only question that Harold raised that is pertinent above is
the question of what I do with all the heat of the tropics when
installing Aluminium Sequin. Well it is expected that the sequin would
decrease the heat of the tropics since it would reflect much of the Sun
rays in the equatorial belt. If my plan works well, then no hurricane
will ever be formed in the Atlantic or Gulf waters because of the
amount of reflection of incoming Sun rays. What I am not so sure of is
whether any harm to the Gulf Stream that keeps northern Europe warm.
There is going to be a diminuation of the Gulf Stream that travels to
Europe, but I expect that it is only a small decrease. In fact the
weather of Europe has been goofy and strange for the past 20 years and
by putting Aluminium Sequin in orbit should restore the weather of
England and Europe to what it was circa 1950s.
As we control weather and climate via Aluminium sequin we provide
stability to climate. If we do nothing, then we are at the whims of
strange, odd weather patterns.
Looking back, all of us should have and could have said that as Global
Warming increases that the first biggest upsets of civilization will be
killer hurricanes that destroy entire regions of the USA and make it
uninhabitable.
So, volcanic activity of the past is not going to be able to model the
application of Aluminum Sequin. Thus we need to prepare for a test
application of sequin as soon as possible. Send a rocket in the next
few months to deposit sequin in orbit over the Gulf and Atlantic
waters. See how it works and behaves and then make preparation for the
real application of Aluminium Sequin before the summer of 2006.
