A circular region within a radius of 400 km of Bermuda has been struck by 188 tropical storms or hurricanes from 1851 through 2005 and by 20 since 1995. Here we describe new direct and remote sensing observations and analyses of recent events near the Bermuda Testbed Mooring including Hurricane Fabian (2003), Tropical Storm Harvey (2005) and Hurricane Nate (2005). The most impressive upper ocean response of the recent events was produced by Hurricane Fabian when SST cooling exceeded 3.5 degrees C, vertical mixing occurred to a depth of greater than 130 m, and upper ocean currents reached 100 cm s(-1). Fabian also triggered an ocean color event visible in SeaWiFS satellite images. Related implications include improved estimates of the roles of tropical cyclones in driving meridional overturning circulation (MOC) and testing of hypotheses concerning warming of the tropical oceans which could cause more intense tropical storms and hurricanes.
