Hurricane Season Overview Oct. 11

Your weather channel is airing charts like this to show how active is this year’s storm season impacting the Caribbean and US east coast.  So far, there have been many more named storms, two more hurricanes than average, and one less major hurricane at this point in the season.  Dr. Ryan Maue provides (here) a global context for understanding storm activity this year, updated October 11, 2020.

So globally, the ACE (Accumulated Cyclone Energy) is 2/3 of the average 1981-2010 at this point in the season.  ACE compiles the storm strengths as well the the number of storms.  Clearly the North Atlantic is 143% of average, but slightly behind 2019.  This indicates that many of the named storms were not that strong.

Meanwhile the Northern Hemisphere is running 69% of average and well behind last year.  This is due to North Pacific having a quiet season offsetting North Atlantic activity.  See the graph below from RealClimateScience

The historical summary of Tropical Hurricane ACE as of September 30, 2020:

Figure: Last 50-years+ of Global and Northern Hemisphere Accumulated Cyclone Energy: 24 month running sums. Note that the year indicated represents the value of ACE through the previous 24-months for the Northern Hemisphere (bottom line/gray boxes) and the entire global (top line/blue boxes). The area in between represents the Southern Hemisphere total ACE.

The hiatus of storms lasted a decade after 2006 (Thanks Global Warming).  Now seasons are more active (Your fault Global Warming), though somewhat less than previous peaks.   Maybe it’s Mother Nature after all.

Don`t worry there is no significant man- made global warming. The global warming scare is not driven by science but driven by politics. Al Gore and the UN are dead wrong on climate fears. The IPCC process is a perversion of science.
