  •  the "eye" feature really isn't at all rare (10+ / 0-)

    in extratropical storms, even before climate change. It appears tropical (and I admit I purposely used that image for that very reason), but it really isn't. The storm is still extratropical.

    It's called occusion--the cold and warm fronts attached to the surface low have combined and a pool of relatively warm air has become trapped in the center.

    Jeff Masters explains here

    Is it a hurricane or an extratropical storm? Satellite image of Winter Storm Nemo taken at 3 pm EST Saturday, February 9, 2013 shows a very hurricane-like storm. The storm had undergone a process known as "occlusion", which trapped a shallow area of warm air near the center. These "warm air seclusions" are not uncommon in intense wintertime extratropical storms, and Nemo was not very hurricane-like in structure, despite the appearance of this satellite image.
    Now there is a climate change aspect to nor'easters, and that is storm surge. Nor'easters can bring wicked storm surges to the east coast (all of Boston's top storm surges were nor'easters and not hurricanes), and as they'll likely be more intense, they'll bring more damaging surges to an already overdeveloped coast.

    •  Thank you for attempting to help people make sense (7+ / 0-)

      Of all this.

      I get seriously steamed when people refer to the flood damage of Katrina in New Orleans as "proof of climate change." No it isn't - it was a level three hurricane there. What the flooding after Katrina was proof of is that our levee system is seriously broken, and that the Army corp of Engineers rarely makes intelligent decisions and rarely take s intelligent actions. (As I type this, millions of people could suffer should the broken down levee system around Sacramento Calif get tested by serious flooding. Probably won't happen this year - we aren't slated for much rain. But next year, who knows?)

      I also get steamed when "meteriologists" on CNN or the Weather Channel start saying "Oh my Gawd - Noes! it was -34 in International Fall, MN yesterday night. That is proof of what strange things the weather is doing."

      It is not unusual to have -34 degrees in Northern Mn. That is called "Winter." What is unusual is that now this factoid is beamed into tens of  millions of homes every day, and since most people in Georgia probably never paid attention to the situation with Montana, Minnesota or Idaho cold front weather before, it seems seriously wrong.

      I was really happy for you to spell out the particulars.

      Offer your heart some Joy every day of your life, and spread it along to others.

    •  Can I just arrange to have only the warmest (1+ / 0-)

      air "secluded" over my house? Just asking. Just during winter, you know.

      Last winter wasn't bad, almost no snow at all (after the blizzard of Halloween).


      I hate winter.

      Hey Punxsutawney Phil, where the hell is our early spring? Ya danged rodent!
