As Hurricane Humberto was rapidly gathering strength just east of the Caribbean late last month, researchers with the University of Southern Mississippi were busy preparing an experiment.
Leila Hamdan, a professor of ocean sciences, and her team loaded two fiberglass sailboats into a truck and headed for North Carolina's coast. From there, the boats set sail for the eye of the Category 5 storm, where they encountered 150 mph winds and waves that rose several stories high.
