Australia Bushfire Season 2019-20 (Weather)

Exactly! I'm sure the rural fire authority has got some twisted reasoning for not releasing them but it seems mainly a case of wanting to hoard their data/intel so they can feel important.

There's a hell of a lot of politics going on with firefighting in Australia - and the US from what i can tell. That's a shame.

Meanwhile the focus moves down south to Adelaide today where they're expecting 42C+ and windy!

Starting to form an idea of how a fire system works meteorologically: seems you get a high which has drifted across the affected area and then sits to the east of it - and then a low pressure below or behind it or wedged up against it - which draws a stream of hot northerly winds off the desert between the rotating wheels of the high (counter-clockwise) and the low (clockwise).

Similar to a typhoon, if that system keeps moving east then at least it passes and the cool-change comes in behind it - the big problems occur when its passage gets blocked and just sits there for a couple of days
