The NAO has only a small correlation with overall U.S. hurricane landfall probabilities, but it appears to influence strongly which regions in the United States are most likely to experience hurricane landfall (Figure 2). Strongly positive NAO values are associated with high intense hurricane landfall probabilities along the East Coast. Strong negative NAO values are associated with high intense hurricane landfall probabilities along the Gulf Coast.
The NAO influences landfall probability for Atlantic hurricanes through changes in the above-mentioned subtropical high-pressure cell over the Atlantic Ocean. A positive NAO index is correlated with elevated pressures in the subtropical high over the North Atlantic Ocean and more frequent re-curvature of Atlantic hurricanes. A negative NAO index is correlated with lower pressures in the subtropical high and a more zonal atmospheric flow that tends to maintain an east-to-west hurricane track.
