Signs indicating Australia's cool season arrival
16:15 AEST Mere hours after our Total Lightning Network went quiet over the Australian continent, the Himawari satellite captured a clear, textbook snapshot of the arrival of Australia's cool season. A few distinguishing features should catch your eye: A band of cloud streaming over northern WA and towards the nation's interior A distinct clearing of cloud from most of the NT's Top End, and A band of cloud crossing to the south of WA Turns out, all three of these features point to one thing: winter is knocking at the door.
