All hopes for some rain after a VERY dry start to the year in southern Vic dashed for most areas. A grand total of 0.4 mm in our local gauge. A reminder that one month (November 2025) doth not a drought, break.

For those in Melbourne today, don't be fooled by the mild morning. The super-hot air is sitting like a giant bubble right above us, waiting for the sun to come up and start mixing all that cooler air at the surface with the air above. When it does, it's going to get hot, fast. Stay cool, stay safe.

Pyrocumulus happen when the immense heat from a fire causes near-surface air rise and break through to unstable layers in the atmos, leading to intense convection. I took this time lapse of the Walwa fire in NE Victoria on Friday afternoon as PyroCu bubbled away over the range from our location.

Had the opportunity to speak at the Senate Committee on Information Integrity on Climate Change and Energy yesterday. We had many questions, including from Malcolm Roberts (ironically). You can see how that turned out, below. Huge props to Alex Dunne, a PhD student in our team who also spoke.

Climate scientists Ailie Gallant & Alex Dunne educate RWNJ Malcolm Roberts on science, & explain that “in the case of climate change there is not strong disagreement” among scientists. Roberts “There isn’t?” It’s like he was born yesterday.🤔 #Estimates

Day 1 of the International Conference on Southern Hemisphere Meteorology & Oceanography in Cape Town, South Africa. Always a luxury not having to flip your circulations and seasons! Lots of talks on drought already, so I'm a happy camper!

New nomenclature alert! High-impact/extreme weather should henceforth be called "battle weather" according to my 5 year old. I will officially adopt this terminology. I can report that said 5-year-old's #1 favourite type of "battle weather" is a supercell.

Our final stop is always a kicker. I would like to say we're just there for the view, but it's so much more than that. As we look out over the area we've been and take stock of the valley as it would have been before colonisation, how it is now, and how it will likely change again into the future.

Out today with our third year "Water and the Land" class. We've measured river cross sections & discharge, identified flow on topographic maps, worked out how precip converts to runoff, chatted water resources at Maroondah Dam and talked rivers & flooding in Yarra Glen! Always a fun day out!

Tropical Cyclone Alfred somewhat looking the part on Friday morning, with gusty cyclonic bands crossing north east NSW and south east QLD, and anticyclonic outflow evident (as cirrus) to the south west.

Cyclone Alfred, T-24-30 hours before it hits the Queensland and NSW coast. Keep an eye on warnings and please, please, please follow the advice of emergency services, especially if you're in low lying areas.

My favourite thing about our building at Monash. Asked by the dept to find an interesting weather image. Ended up that extra bit special for me - it's the day my daughter was born (of course the daughter of two atmos/ocean scientists would be born on such spectacular and interesting weather day 😁)

"Predictability and reliability is an asset in the global economy." EU Director-General Kurt Vandenberghe. This is EXACTLY why the science is critical to maintain and grow. If we can't understand the climate system, we can't predict it.

At a talk by the EU Director-General Kurt Vandenberghe. The transitions in the EU are impressive. He's describing the transition to net zero as a driver of competitiveness, "shock therapy" for modernising Europe.

A wintery mid-summer blast in Southern Victoria this weekend. We had a "beach weekend" planned but had an adventure in a dune field near Wilson's Promontory National Park instead. Winds at the closest gauge were sustained at 60km/h and gusting to 80km/h at the time. My retinas got a good polish!!
