Comment About Sandy

On Thursday Felix Welzenbach has left a new comment on your post "Sandy Disaster":

Unfortunately, I did not find any maps with wind gusts produced by SANDY. However, water vapour image suggests that a sting jet could have been present with Sandy at the tip of the occlusion front where dry air descended. Is this in accordance with the occurrence of strong wind gusts during landfall?

Hello Felix,

It appears that the strongest gusts were with the east winds to the north of the lowest surface pressure. I think that the gusts were strong at the tip of the "scorpion's tail" but weaker than the winds along the coastal areas. There were so many posts going on, that I didn't redo any of them on this blog.

Note that there is already a draft paper on details of the storm from Rich Grumm - you can take a look at his analyses at this url:         http://nws.met.psu.edu/severe/2012/30Oct2012.pdf

On Friday, From Felix - Hi Bob, thanks for your answer and the link. Interesting paper. So translation + rotation in the right-front quadrant of the storm has been responsible for most of the maximum wind gusts, and sting jet dynamics were not as important as rapidly deepening and isallobaric winds ?!   Felix

Felix,

I think that there were several unusual aspects to Sandy. It is not clear exactly when Sandy transitioned to an extra tropical storm. When the winds were strongest, the low was moving rapidly toward the west - an unusual situation. When Sandy became a warm seclusion inland, the pressures were mostly rising. So, I think that one could say the poison of the sting jet was neutralized by the unusual aspects of the storm motion and its rapid weakening after it was inland. I'm sure there will be numerous papers coming on the details of how Sandy transitioned to an extra tropical storm.
