How frigid polar vortex blasts are connected to global warming

Life-threatening cold temperatures in the central US are caused by changes in wind circulation in the Arctic that bring cold air south. Climate change could make these events more frequent.

Curious Kids: how do people know what the weather will be?

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.
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. Dean Lewins/AAP

Sydney storms could be making the Queensland fires worse

Bushfires across Queensland are fanned by high winds pushed north by a strong low in NSW.
A hot summer will mean wetlands dry out faster than ever, so how will pest mosquitoes respond? Cameron Webb (NSW Health Pathology)

Will the arrival of El Niño mean fewer mosquitoes this summer?

The forecast arrival of El Niño may mean the east coast of Australia will experience an exceptionally hot and dry summer, but does this mean there will be fewer mosquitoes buzzing about?

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. Robert Lawry/Author provided

Curious Kids: where do clouds come from and why do they have different shapes?

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.
