Ailie Gallant 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.
Ailie Gallant Today's rain in western VIC from a typical "autumn break" system (decently strong mid-lat cyclone). But instead of dropping 20-40 mm (typical in a 'normal' year) most areas got 5-15 mm. This is very typical for dry periods - see our work on this from last year. journals.ametsoc.org/view/journal...
Ailie Gallant Officially my favourite headline of this Federal election, as seen on the ABC News website this morning 馃ぃ Australian politics at its finest.
Ailie Gallant 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.
Ailie Gallant 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!
Andrew Miskelly 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.
Ailie Gallant 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.
Ailie Gallant 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 馃榿)
Ailie Gallant 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!!
