Hurricanes and Noreasters

[Jim Cantore]

Is it possible that they could be related in a way, like distant cousins?

[george_r_1961]

Very distant. Hurricanes obtain their energy from warm water and the latent heat released by convection, while noreasters are frontal type systems that derive their energy from the temperature differences on the frontal boundary, among other things. Hurricanes transforming into noreasters is a common occurrence and it isnt unheard of for a strong cold core system to develop convection near the center and become warm core. So yes they are distant cousins.

[wxmann_91]

Yes and no. Two totally different creatures, yet in many cases the Gulf Stream does help fuel a noreaster. There was a good explanation I think on this either here or another forum, and it's way too crazy for me to comprehend. I just know there is an effect. And remember hurricanes can transform into noreaster-type extratropical lows and also that big noreasters can eat up dying hurricanes and use their energy.

Beautiful Avatar wxmann 91. Did you save any of the images of the eye of this incredible nor'easter?

[Hybridstorm_November2001]

True. Remember the "Halloween/Perfect Storm" that absorbed Grace in 1991. Probably the most infamous example of Nor'Easter and Hurricane merging into a strong hybrid, or subtropical if you will, type entity.


PS: Also take a look at my avatar for an even more extreme (in terms of pressure), but less destructive (because it didn't stall and loop around the same area for the better part of a week) example of such a composite entity near peak strength.

Yes

I have more images but this one IMO is the best:

I do recall that

Hurricane Noel I believe

[Hybridstorm_November2001]

Good memory! Both Hurricane Michelle and TS Noel actually.

[Jim Cantore]

They both merged didnt they?

[Hybridstorm_November2001]

Both eventually got absorbed by a forming Nor'Easter off New England, to make the storm in my little window.

[brunota2003]

the "Un-named Hurricane of 1991" also formed in the center of that extra-tropical low!!! That was not only an awesome hurricane, but, IMO, pretty as well...

Here is a close up of the "Un-named Hurricane of 1991"

Isnt she purty???

it's all weather...

If that pulled a 1991 it may have been worse, that was a stronger syestem pressure-wise

[Hybridstorm_November2001]

Very true. Also the pressure gradient was ever a bit larger than the 1991 storm, besides the lower pressure. If it had done a slow loop it could have done much great damage indeed, and over a much larger area. I'm glad it was a relatively fast mover, both for myself and the those further West and South
