Hurricane tracks are influenced by large scale atmospheric circulation features, such as North Atlantic Oscillation (NAO). This oscillation is characterized by an enhanced deep Bermuda High Pressure system during its positive phase.

Tropical cyclones tend to track closer to the East coast of the U.S. during the positive phase of the NAO (red tracks).

Tropical cyclones tend to recurve prior to reaching the East coast of the U.S. during the negative phase of the NAO (blue tracks).
