In 1887 Queensland’s chief weatherman Clement Wragge began naming tropical cyclones, using names from the Greek alphabet, fabulous beasts and politicians who annoyed him.
The Cape Grim observatory, home of the ‘world’s cleanest air’… and rising greenhouse gases.
Carbon dioxide levels in the atmosphere are at 414 parts per million. But thanks to a recalculation of methane's warming power, the total amount of greenhouse gases is now equivalent to more than 500.
The sea is blue because of the way water absorbs light, the way particles in the water scatter light, and also because some of the blue light from the sky is reflected.
Photons stream from the sun and interact with all matter on Earth. Depending on what the light touches, some of the photons will get absorbed or soaked up. And some will bounce back.
Dirty water from Queensland’s historic flooding, triggered by weeks of exceptional monsoon rains earlier in the year.
The hottest Australian summer on record is ending, and it's likely we've got a warm, dry autumn to come.
Tree trunks, which were submersed when the dam was full, stand a the critically low dam in South Africa in 2018.
Australia's subtropical regions are drying, but if we can slow the global temperature rise then rainfall should increase again.
Sea ice responds to changes in winds and ocean currents, sometimes with origins thousands of kilometres away.
Antarctic sea ice cover fell to an all-time low recently and hasn't yet recovered. Why? The initial answers could lie in an unlikely place – the tropics.
Queensland’s ‘unprecedented’ bushfires were part of a year of extremes.
2018 was Australia’s third warmest year on record, as the NSW drought dragged into another year.

Fire danger conditions are worsening in many areas of Australia.

Australia is facing an increase in extreme heat, fire danger weather, floods and marine heatwaves, according to the latest biennial snapshot from the Bureau of Meteorology and CSIRO.
Meteorologists use their own experience, which helps them to decide whether the computer’s prediction is likely to be right.

Twice every day the Bureau of Meteorology sends out the official weather forecasts for towns and cities across Australia. Here's how we work out what to say in them.
Queenslanders have taken to the water in the face of record-breaking heat.
The summer forecast from the Bureau of Meteorology predicts a hot, dry summer.
Storm clouds move over the Illawarra south of Sydney on Wednesday, November 28 2018. Sydney received more than a month’s worth of rain in just two hours, with Observatory Hill recording 84.6mm by 7am. The November average is 83.8mm.
Bushfires across Queensland are fanned by high winds pushed north by a strong low in NSW.
Maximum temperatures for January to September were the warmest on record for the Murray–Darling Basin and New South Wales.
After the warmest month on record, it looks like Australia will have an El Niño event – which means the drought is likely to continue.

Australia must come to terms with some fundamental shifts in our weather patterns. This month, Andrew Watkins from the BOM and climate scientist Joelle Gergis explore what's in store.

Are our extremes moving past historical precendent into uncharted territory, or is this life as usual on a changeable continent?
Sometimes air goes up past the condensation level then falls back below the condensation level, then up, then below, again and again. This creates clouds that are stripy, often with lines between the clouds.

Clouds formed by rising warm air currents are called 'convection clouds'. Because of all the rising air coming up, these clouds can be bumpy on top, sometimes looking like cotton wool or cauliflower.
It’s unlikely NSW will get the sustained rain needed to break the drought.
A new outlook from the Bureau of Meteorology forecasts a dry, warm spring – and not the sustained rain we need.
If you live in a place where the weather moves west to east, then an old proverb could help you predict the weather.
The "red sky" proverb has endured across cultures for centuries, and modern science can explain why this is so.
Brrr! It’s cold in here!
Winter is here, and many farmers are still waiting on their 'autumn break' of heavy rain. Unfortunately, it looks like it will be a dry, warm winter – although the snow season will likely be good.
