Ocean's Color Affects Hurricane Paths

ScienceDaily (Aug. 14, 2010) — A change in the color of ocean waters could have a drastic effect on the prevalence of hurricanes, new research indicates. In a simulation of such a change in one region of the North Pacific, the study finds that hurricane formation decreases by 70 percent. That would be a big drop for a region that accounts for more than half the world's reported hurricane-force winds.
