I've been wondering what made Sandy different from an ordinary hurricane, and you explained it nicely. But, a couple more questions: is its large size caused by the high pressure zone it's hitting, or is it unusually large for some other reason? Also, I've seen our weird northeast weather from last spring explained as a change in the jet stream, but it seemed in that case as if it was moving around less than usual, or changing position more slowly than usual, or staying in the far north instead of moving down into the mid latitudes, or something like that, and I'm wondering how the two phenomena are related. Thanks!
