Australian Bureau of Meteorology
The Bureau of Meteorology is Australia’s national weather, climate and water agency. Its expertise and services assist Australians in dealing with the harsh realities of their natural environment, including drought, floods, fires, storms, tsunami and tropical cyclones. Through regular forecasts, warnings, monitoring and advice spanning the Australian region and Antarctic territory, the Bureau provides one of the most fundamental and widely used services of government.

We already know that climate change makes heatwaves hotter and longer. But a new series of research papers asks whether there is also a climate fingerprint on frosty spells and bouts of wet weather.
New “dual-pol” weather radars promise to spot large hailstones forming inside thunderstorms, giving people a heads-up when it’s about to hail.
Weather forecasters sounded the alarm for the record-breaking Hurricane Irma with several days’ notice.

October 2015 was the hottest on record for that month, and Tasmania had its driest ever spring.
Researchers from a range of disciplines need to work together if we are to predict and prepare for the next thunderstorm asthma event.
Cape Grim’s air pollution station has recorded some of the biggest changes to the world’s atmosphere over the past 40 years.
The new State of the Climate report outlines Australia’s rising temperatures and its regional rainfall declines - and the trends that are locked in for the coming few decades due to greenhouse emissions.
Australia is facing an above-average cyclone season, with at least 11 cyclones likely in the region.
The Indian Ocean Dipole may be El Nino’s less famous cousin, but that hasn’t stopped it having a profound effect on Australia’s weather since it flipped into a “strong negative phase” two months ago.
From floods to drought, fire to famine, the 2015-16 El Nino has had a global impact.
