The complicated connection between climate dynamics and hurricane strength and frequency continues to get more complex with each piece of research that is released.The latest research, as published in the journal “Nature”, indicates that even during periods when ocean waters were cooler, hurricanes were more frequent.
While this doesn’t directly dispute the popular belief that hurricane frequency increases with warmer ocean waters, it certainly complicates things:
Study Finds Hurricanes Frequent in Some Cooler Periods
By ANDREW C. REVKIN
Over the last 5,000 years, the eastern Caribbean has experienced several periods, lasting centuries, in which strong hurricanes occurred frequently even though ocean temperatures were cooler than those measured today, according to a new study.
The authors, from the Woods Hole Oceanographic Institution, say their findings do not necessarily conflict with recent papers asserting a link between the regionâ€™s hurricane activity and human-caused warming of the climate and seas.
But, they say, their work does imply that factors other than ocean temperature, at least for thousands of years, appear to have played a pivotal role in shaping storminess in the region.
The study compared a 5,000-year record of strong storms etched in lagoon mud on the Puerto Rican island of Vieques with data on ocean temperatures and climate and storm patterns. The analysis is being published today in the journal Nature.
