with the Tropic of Capricorn running virtually through the middle of Australia our weather is a function of the polar weather system meeting the equatorial weather system creating a weather zone similar to the ITCZ, which spans and moves back and forwards across the equator.
The greater the differential between the polar weather systems and the equatoriall weather system the more variable our weather will be as the forces in each of the systems clash. The opposite also applies.
