Melting Arctic sea ice aims Frankenstorm Sandy directly at the Big Apple

Frankenstorm Sandy is a scary beast. A hybridization between a tropical hurricane and a mid-latitude cyclone, her behavior is not natural at all. Moving northward off the east coast, Sandy is turning left toward land instead of right toward the sea.

Thus the designation “Frankenstorm”.
Because the Earth rotates on its axis, circulating air deflects toward the left in the Southern Hemisphere and to the right in the Northern Hemisphere. This deflection is called the...
