Are Powerful Hurricanes Becoming More Frequent?

According to Kerry Emanuel :

“Most of the models suggest that the more powerful storms become more numerous.”

” While hurricanes might become more powerful, Emanuel said, there will likely be fewer hurricanes overall this century, and hurricane trends would vary widely around the globe.

The graph above plots the ten year running mean of the number of category five hurricanes making landfall. As you can see, the peak occurred during the 1930s and it has been relatively level since. There were four category five hurricanes which made landfall between 1924 and 1935, but only two during the past decade. It has been 18 years since a category five hurricane struck the US.

At some point, people need to check and see if their models actually work!
