By grouping weather systems by similar patterns rather than averaging conditions over months, seasons or years, CLEX researchers found that between Australia and Antarctica, the ‘doughnut’ structure of SAM is split into multiple ‘flavours’ and is more likely to have ‘bite marks’ out of it than be a perfect ring.

Research brief: Natural variations shift rain-bearing winds south

CLEX researchers found the influence of climate change and the depletion in stratospheric ozone are the major drivers over the Atlantic Oceans that shift westerly winds further south. However, over the Pacific and Indian oceans natural variations induced by sea surface temperature changes in the tropical Pacific also play an important role.
