Drought is a quintessentially Australian experience, yet many of us don’t properly know how they form.

High temperatures make droughts worse, right? Wrong: it's the other way around. Ahead of an El Niño summer that looks set to bring drought to much of Australia, here's a quick primer on how they form.
El Nino brings drought to Indonesia, and warmer weather to almost the entire globe.
El Niño has a hugely pervasive effect on global temperatures - for every degree the tropical Pacific warms, land temperatures warm by 1.5 degrees. How? Because the tropical ocean is a very good heater.
This summer’s El Niño is likely to bring more frequent heatwaves to a large swathe of Australia’s north and east.
The link between El Niño and heatwaves is complicated. But what we can say is that this summer's strong El Niño conditions are likely to bring more heatwaves to much of Australia's north and east.

Storm clouds for California?
El Niño explained: how it works, what a mega El Niño this year could bring and how global warming might affect future El Niño-driven weather patterns.
Storms coming? El Niño is projected to lead to much-needed rain in California next year.
El Niño is expected to bring heavy rains to drought-stricken California, but more rain alone won't solve the West's water crisis.
Children from a village in Papua New Guinea’s Western Highlands Province stand in one of countless sweet potato gardens destroyed by frost across the country, August 2015.
Papua New Guinea is now facing a drought and frosts that look set to be worse than 1997, when hundreds of people died. So how can memories of 1997 save lives over the next few months?
People in the Philippines have been warned to brace for wet and wild weather, as this year’s El Nino shapes up to be the strongest since 1998.

The seesaw between El Niño and La Niña is set to get stronger with global warming. Signs are that this year and next will deliver a big swing from one to the other, prompting fires and floods across the world.
The large 1982 El Niño contributed to the Ash Wednesday bushfires that killed 75 people in south east Australia.
El Niño has arrived, it's getting stronger, and it's not about to go away soon. And already there are rumblings that this could be a big one.

Over the past 80 years sardine and anchovy have become icons of modern-day marine biology, oceanography and climate research.
Future snows will mostly happen in big falls.
This weekend is predicted to be the coldest of the year in Australia. But it has otherwise been a slow start to the snow season, and my research shows that this is a sign of things to come.

While eastern Australia trembles in the face of an El Niño, Western Australia's oceans could finally see relief from devastating marine heatwaves.
Warming seas suggest El Niño is on the horizon.
El Niño is officially on, and comparing it to previous events suggests it could be big one, perhaps leading to record-breaking temperatures.
El Niño is often associated with drier conditions in winter and spring in eastern Australia.

The threat of an El Niño has not gone away for Australia.
This last year we were preparing for an El Niño. But then it all just fizzled out. So what happened? And could this be the year?
