Slingshot Atmospheric Rivers .

9 Nov 2014
Synopsis :
Atmospheric Rivers can slingshot around very low depression
systems , picking up energy from the jetstreams and dumping extremely large
masses of water and snow into lower latitudes .
Discussion :
0.A broader discussion of slingshots and barycenters can be
found at https://www.academia.edu/9162437/BaryCenter_Update_I
1.Important Concepts for storms :
1.1Extratropical storm system conversion
A tropical hurricane or typhoon moves into colder latitudes
and loses energy .
But , it connects to low-level atmospheric rivers and high-level
jetstreams and picks up energy from both .
1.2 Bombogenesis
The hot core of the typhoon converts to a cold core very
rapidly , as very cold air from the jetstreams spiral in . If an atmospheric
river is nearby (as it usually is) , enormous amounts of latent energy is
released . This creates a sudden vortex
of very low pressure , creating very high winds .
2.The Slingshot :
The low-pressure vortex acts like a gravitational mass in
orbital mechanics .
A characteristic of atmospheric rivers is that they are
delineated . So some atmospheric rivers feed the vortex , while others a bit
further away slingshot around it .
This dumps billions of tons of water , snow and slush into the lower latitudes .
The North American Continent has suffered numerous episodes
.
Enormous floods , followed by ice-ages , then floods again
as the ice-dams collapse .

3.Slingshots :
This is a very well-understood phenomenon .
How to steer an atmospheric river is discussed in
So , we can steer atmospheric rivers to slingshot around
storms like 2014Nuri and rain a lot further south .
The physics is easy . The politics ?
4. Is there any chance of an atmospheric slingshot with the
present (Nuri Nov2014) system ?
From the old Mark One eyeball , I count at least 6
atmospheric rivers inside the system .
Look at the dark breaks . The only thing strong enough to
maintain some semblance of identity is an atmospheric river .
So , using our old 1/3 principle , we can expect about 2
ArkStorms from this episode .
This is thumbsuck , but my closest estimate is one in
Western California and another on a more
west-to-east direction over the great lakes . (Where did they originally get
their water from ? . Also those flood gorges towards the Atlantic might be a
recurrent thing)
5.Climate warming .
Another of Gaia’s little surprises .
Slingshot distribution of atmospheric rivers slows global
warming , by distributing tropical heat in a positive feedback fashion .
The hotter it gets , the more atmospheric rivers and tropical
storms converts to bombogenesis . This means more atmospheric rivers cool down
, then slingshot back towards the equator .
A sort of planetary air-conditioning .
This can be steered by humans .
However , it also means extreme rains .
6. Southern Hemisphere .
This is different from the northern hemisphere .
There is much more water .
So , a rough sketch would be atmospheric rivers slingshotting
around Antarctic bombogenesis events , then moving northwards over open ocean
faster than rotation .
It means that the river picks up speed in spin direction .
The ArkStorms will then be inclined to hit the western
coasts of the southern continents .
See http://andreswhy.blogspot.com/2010/10/makgadikgadi-sea.html
, where the western rainfall was significantly higher .
But I might be wrong and this picture is what is waiting .
Not exactly what Noah had in mind .
7.Testable .
This is in direct contradiction of present climate warming
models , where dessication occurs from west to east .
So , it can easily be tested . Feed atmospheric river
slingshots into the models , and see what happens .
The geological evidence shows flooding , but it does that
anywhere . If you wait long enough , it will flood .
8. Pre-emptive slingshots :
Air condition the whole planet .
And so it slings along .

Fans of The Deadliest
Catch know that the Bering Strait isn’t exactly a tranquil region, but what is
about to happen may set a new all-time record for the strongest storm the area
has seen since at least the 1950s.
In other words:
Fishermen need to get the heck out of there. Now.
SEE ALSO: How Typhoon
Nuri is changing the weather forecast in North America
Computer models have
been signaling for days that the remnants of what is now Typhoon Nuri — once
the second-most intense tropical cyclone on record this season — will undergo a
transition into an extratropical storm system as it moves northeast, away from
Japan, over the next few days.
As it does so, the storm
will likely encounter an unusually intense North Pacific jet stream that is in
a favorable position to give it a major injection of intensity — like a storm
that drinks a six-pack of Red Bull.
Other factors will also
aid in intensifying the remnants of Nuri.
….The sudden deepening of an extratropical low pressure system is referred to as “bombogenesis,” and this storm looks like it will meet the criteria for that, and then some.
…in part by rendering
alternate airports in Alaska useless, as they are buffeted by hurricane force
winds of nearly 80 miles per hour or greater. Seas are forecast to build to at
least 50 feet in the southwest Aleutians, and potentially higher in the Bering
Strait.
