Question
Did global warming effect hurricane sandy?

Answer
Hi Sandy

So far the only impact from recent (last few years) of regionally warmer ocean temperatures related to hurricanes (tropical storms) has been on the strength of the storm winds along with and from lower barometric (atmospheric) pressure.

With respect to hurricane Sandy, the unusual aspect was the left turn that brought the storm due westward onto the New Jersey coastline. The cause of that turn to the west was a negatively tilted upper level trough with a blocking surface high pressure to the north of the storm.
