KEY FOR FIGURES
Pot# = Potential Tropical Cycle number #
TD = Tropical Depression
TS = Tropical Storm
CATN = Category N Hurricane where N = 1, 2, 3, 4, or 5.
PK = Peak Activity
Regen. = Regenerated
Note: All but two (the exceptions being Jose and Katia) of the 15 Topical Depressions/Storms/Hurricanes that occurred during the North Atlantic Hurricane season supports the following claim that:
Tropical depressions or storms that appear in the Atlantic Ocean between the Equator and 25.0 degrees North during the North Atlantic Hurricane season, will do so on dates that are maxima or minima in the lunar-induced changes in the relative angular velocity of the Earth's rotation. [N.B. the dates that are maxima or minima in the lunar-induced changes in the relative angular velocity occur close to the times when the Moon crosses the Earth's equator or reaches lunar standstill (i.e. the Moon is furthest north or south of the Equator).]
This claim is also supported true by 10 of the 12 Topical Depressions/Storms/Hurricanes that occurred during the Hurricane season 2016.
