• Location and Movement

  Hurricanes form in the tropics (but not around the Equator) and initially move from east to west with a discrete well-defined low pressure center. Hurricanes move with the wind. Mid-latitude cyclones occur in the mid-latitudes and move west to east with centers of low pressure that may dissipate and re-form further downstream. Mid-latitude storms move as temperature advection drives pressure falls ahead of the storm.

• Environment

  Hurricanes need warm ocean surface and weak vertical wind shear throughout the troposphere to develop. Mid-latitude storms are at home with shear and require horizontal temperature gradients to develop.

Hurricanes can transition into cold-core cyclones once they exit the tropics. It is possible, but not common, for a mid-latitude cyclone to transition into a warm-core tropical cyclone.
