Periodically, the cross connection between abnormal solar activity and hurricanes is mentioned in the ALT-SCI press.

It is a complex interaction but there seems to be something beyond coincidence going on in this alignment. Often water temperature is said to play a role in hurricanes, but this year the Ocean water temperature in hurricane alley is normal Perhaps the sunspot itself is not the driving force for more intense storms on earth but instead, the sunspot feeds a greater tonnage of dense hydrogen into the solar wind, and that dense hydrogen becomes the driving mechanism for the extra power of the storm.
