| Abstract | The 2005 North Atlantic hurricane season ( 1 June to 30 November) was the most active on record by several measures, surpassing the very active season of 2004 and causing an unprecedented level of damage. Sea surface temperatures (SSTs) in the tropical North Atlantic (TNA) region critical for hurricanes (10 degrees to 20 degrees N) were at record high levels in the extended summer ( June to October) of 2005 at 0.9 degrees C above the 1901 - 70 normal and were a major reason for the record hurricane season. Changes in TNA SSTs are associated with a pattern of natural variation known as the Atlantic Multi-decadal Oscillation (AMO). However, previous AMO indices are conflated with linear trends and a revised AMO index accounts for between 0 and 0.1 degrees C of the 2005 SST anomaly. About 0.45 degrees C of the SST anomaly is common to global SST and is thus linked to global warming and, based on regression, about 0.2 degrees C stemmed from after-effects of the 2004 - 05 El Nino. |
