North Atlantic Hurricane Stats For 2014

January 3, 2015

By Paul Homewood   

 

I took a look at global tropical cyclone stats yesterday, but I thought it would also be useful to have a look at the situation in the North Atlantic.

 

First, hurricane numbers. These include all hurricanes, whether making landfall or not.

And Accumulated Energy:

On both measures, the last two years have been unusually quiet, and there is certainly no evidence of hurricanes increasing in frequency or intensity.

 

Finally, it is worth noting what NOAA have to say about the Atlantic Multidecadal Oscillation:

 

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.

 

We are, of course, still in the warm phase of the AMO.

    Thanks, Paul. Your annual ACE graph is very useful.
    Dr. Maue’s shows the monthly figures. But your simplification makes the point even more clear.
