The regional climate of planet Earth is controlled by the amount of energy received from the Sun and the way it is dispersed or redistributed. The Sun, like other stars, is a variable star emitting varying energy due to sunspot and magnetic activity cycles. The amount of solar energy incident at a location on Earth is constantly modulated on a variety of timescales ranging from millennia to seasons due to periodic changes in the Earth’s orbital precession, eccentricity, obliquity, etc., and the changing environmental conditions. The Earth receives maximum heat from the Sun over the tropics and distributes it polewards through atmospheric and oceanic circulations.The regional climate of planet Earth iscontrolled by the amount of energy receivedfrom the Sun and the way it isdispersed or redistributed.
