“I think we do see a climate signal here,” said James B. Elsner, a professor of geography at Florida State University who is the lead author of the paper, being published in Thursday’s issue of the journal Nature.

The study, which also found that more typical, less powerful tropical storms had not become stronger over the 26-year period studied, is consistent with other researchers’ hurricane models, Dr. Elsner said.
