Counting Cyclones

Chris Landsea at the National Hurricane Center wrote an excellent piece a few years ago, explaining why they name more storms than they used to.

It basically comes down to better monitoring techniques. With satellites, they find more storms in the mid-Atlantic.

More storms are named now :

But a smaller percentage of the named storms make landfall.

This is due to two factors. Fewer hurricanes are making landfall, and more hurricanes are found now far from land. All hurricanes are shown in blue, and major hurricanes are shown in red in the graph below.

Conclusion : There is no valid reason to believe that any type of Atlantic storms have become more common.

    Have you noticed the AMO signal in all the posts today?

    There are so many multi-decadal oscillations out there, it is reasonable to expect them to combine in various ways and give us cyclical climatic phenomena.

    That certain agendas need to selectively interpret “short-term” results (less than full interactive cycles) is not surprising.
