Will spring bring an end to the cold and the rain?
By following moisture from the oceans to the land, researchers worked out exactly how three oceans conspire to deliver deluges of rain to eastern Australia.
After one La Niña, the Pacific sometimes retains cool water which enables a second La Niña to form.

Out of the last six years in Madagascar, five years have had poor or very bad rainy seasons.
Last week the Bureau of Meteorology declared a negative Indian Ocean Dipole — a natural climate phenomenon set to bring wet weather. Let’s look at what you can expect, and the role of climate change.
Future extremes from the Indian Ocean will be acting on top of global warming, giving a double whammy effect, like the record-breaking heat and drought we saw in 2019.

The absence of climate drivers – specifically, the Indian Ocean Dipole and La Niña – explains why Australia has gone so long without heavy rains.
Some parts of Australia have enjoyed excellent rainfall this year, but others have not. Drought relief is still slow and patchy.
Australia is a bushfire-prone nation. But several factors make this fire season worse than those past.
The latest bushfires cannot be compared to Ash Wednesday or Black Saturday. Our nation’s fire history is being rewritten.
Firefighters battle bushfires in Angourie, northern New South Wales, on September 10 this year, marking another early start to the season.
Bureau of Meteorology researchers painstakingly analysed more than 40 years of data to work out exactly what is causing Australia’s spring bushfire phenomenon.
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.
Much of Australia is set for a hot April.
Record-breaking April heat is likely to continue for at least another month.
It’s more important to know whether there’ll be any weather than what the weather will be.

The Bureau of Meteorology’s climate outlook for April to June is ‘neutral’, but that doesn’t mean we’re flying blind, weather-wise.

Since 1999, Australia has swung between drought and deluge with surprising speed, because El Niño has fallen into sync with similar patterns in the Indian and Southern Oceans.
When the Indian Ocean combines with El Niño dry conditions come to Australia.

We thought the big El Niño might not bring drought. And then the climate turned dry. And hot.
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.
Drought conditions are set to become more frequent with the changing behaviour of the Indian Ocean.
Over the past few months, a lot of attention has been paid to the potentially strong El Niño event brewing in the Pacific Ocean. But there is also the potential for an emerging climate phenomenon in the…
