Warm Core, Cold Core and Extratropical storms...

[andrewr]

We get extratropical systems in the Pacific Northwest, most noteably the "Columbus Day Storm of 1962". Here is an article on it and I believe it was one of, if not the, "windiest" extratropical systems on record : http://en.wikipedia.org/wiki/Columbus_Day_Storm_of_1962

I read on a separate site that Cape Blanco, Oregon may have had sustained winds as high as 150mph with gusts to around 180mph.

Lowest pressures recorded in a cold core system are below 920 mb in a storm near Greenland in December 1986 and around 925mb in a storm in the Aleutians on this date in 1977.

The '86 storm was thought to be a little lower in pressure, possibly as low as 912.

"A ship at some distance from the centre of the storm recorded a pressure of 938.8 mb. Later, when the storm started to move a little more towards the north-west, another ship reported 926.2 mb. The same ship reported 920.2 mb at midnight on the 15th - it was still at some way from the centre."

Man, that's low!

Vince is a perfect example of a "hybrd" tropical system. The pressure falls were not coming from deepening convection at the center of storm but rather north of the actual system's center where baroclinic forces were stronger. As has been pointed out before calling a 45 mph named system tropical, subtropical or hybrid means little to those that face the systems winds. It is a point of discussion for weather people. I would disagree that Wilma was a hybrid. Correct me if I'm wrong but Wilma had a definite warm core eye, went through eye wall replacements and reached Cat 3 strength. Or perhaps your discussing Wilma once she merged with the trough in which case by then she had lost all tropical characteristics.

I think that's the case here.

WxMann91, thank for the 500mb link... very interesting and I even understood more than half of it!

andrewr, the link about the Columbus Day 1962 storm is an EXCELLENT read. WOW, I had no idea that was possible.
