Typhoons and Potential Connections to Alaska

That's super typhoon Jelewat, which presently has maximum sustained winds of 135 mph, with gusts to 165 mph.  The maximum significant wave height is 48 feet.  That will get your attention.

The current track forecast has it turning clockwise, brushing by Taiwan and then moving across Okinawa.  Little wonder why the US Navy and Pacific Air Forces are so concerned about typhoons.

I've been looking at the long-range forecasts produced by the GFS and after undergoing what is known as extratropical transition, the remnants of Jelewat move over Nome, Alaska by October 4th.  The weak low center over western Alaska in the image below is it.

It is pretty common for tropical cyclone remnants to move across the North Pacific and undergo reintensification (a process known as extratropical transition).  Many move into the high latitudes.  What role do these events play in the climate of Alaska and the Arctic?  This strikes me as a potentially interesting avenue of research.  Some relevant discussion of major events from weather historian Christopher Burt is available here.
