2007) SST and North American tropical cyclone landfall: a statistical modeling
We employ a statistical model of North Atlantic tropical cyclone (TC) tracks to investigate the relationship between sea-surface temperature (SST) and North American TC landfall rates. The track model is conditioned on summer SST in the tropical North Atlantic being in either the 19 hottest or the 1...

Compared to direct analysis of historical landfall, the track model reduces the sampling error by projecting information from the entire basin onto the coast.

The Yucatan suffers 3 times greater landfall rate in hot years than cold, while the U.S. mid-Atlantic coast exhibits no significant change.
