Climate Realist: New Paper: US Hurricane Counts are Significantly Related to Solar Activity

The authors report on a finding that annual U.S hurricane counts are significantly related to solar activity. The relationship results from fewer intense tropical cyclones over the Caribbean and Gulf of Mexico when sunspot numbers are high. The finding is in accord with the heat-engine theory of hurricanes that predicts a reduction in the maximum potential intensity with
a warming in the layer near the top of the hurricane.
