Default Tornadoes in hurricanes

In article ,
says...

Just wondering if anyone knew of any links on the web that went into the
formation of tornadoes within hurricanes? Simon

Googling for tornadoes in hurricanes got me precious little. I'm sure
Harold Brooks could advect in at this point - and point you to somewhere
useful.... (:

Tornado Outbreaks Associated with Landfalling Hurricanes by Verbout,
Schultz, Leslie, Brooks, Karoly, and Elmore
I'm sure he can add more,


We learned this week that the paper was rejected, so I'm not sure what I
know.:-) BTW, if any of you are Reviewer B or C, I only have this to
say:

"Your mother was a hamster, and your father smelled of elder berry."

Back to the subject at hand, Bill McCaul is probably the world's expert
on hurricane-spawned tornadoes. He put some lecture notes on line at
http://www.asp.ucar.edu/colloquium/1998/mccaul.html.

Most hurricane-spawned tornadoes are the right-front quadrant of storms
as they approach landfall or after landfall moving from south to north.
As a result, most of the major outbreaks, at least, have occurred with
landfall on the Gulf Coast, east of Texas. Convective available
potential energy and low-level shear tend to be highest in that
quadrant. It's a shear-rich environment, even though CAPE isn't all
that high (typically less than 1000 J/kg). Most of them form in cells
in the outer rainbands. The tornadogenesis process isn't likely to be
very different from supercell processes in low-CAPE, high-shear
environments.

They tend to be shorter-lived and weaker than isolated supercell
tornadoes, probably because of the relatively small size of the storms
and the really strong shear ripping them apart.

HTH,

Harold
