The sea temperature fluctuations North and South of the Equator are responsible for seasonal events such as hurricane season and Arctic sea ice development and disappearance.

The old 'tilting' hemisphere explanation doesn't work for contemporary concerns insofar as the fluctuations are due to two separate surface rotations of the planet working in combination. The forward motion of the Earth through space turns the surface slowly, unevenly and parallel to the orbital plane thereby influencing the degree of solar radiation or its absence that latitudes experience as a function of daily rotation.

Hurricanes thrive at this time of the polar day/night cycle (Northern evening) just as localized thunderstorms tend to form in late afternoon/evening
