Huge congratulations to Xinyue Zhang on submitting her PhD thesis! 🎉
Her research shows how dryland vegetation responds to climate change, with most areas continuing to green while some face desertification. This highlights the crucial role of sustainable land management.
We are so proud!

@unswbees.bsky.social

Air temperatures over Antarctica have soared 35ºC above average. What does this unusual event mean for Australia?

The stratospheric polar vortex high above Antarctica has rapidly heated up. These sudden bursts of heat can bring rapid weather changes in Australia

Are you interested in the drivers of extreme wind gusts in NSW, Australia?
This new study finds that environmental instability diagnostics (MUCAPE, DCP, etc) are more influential than environmental wind speeds and moisture parameters alone in predicting observed extreme gusts (≥25 m/s). Read more:

Statistical and theoretical models of wind gusts may be dominated by more common strong events, rather than rare but damaging extreme ones. We address…
