How important is the AMO when it comes to hurricanes – in other words – is it one of the biggest drivers? Or Just a minor player?
During warm phases of the AMO, the numbers of tropical storms that mature into severe hurricanes is much greater than during cool phases, at least twice as many. Since the AMO switched to its warm phase around 1995, severe hurricanes have become much more frequent and this has led to a crisis in the insurance industry.
