The research helps us understand how El Niño and La Niña will change as the world warms in the future.
UNSW Sydney experts available to comment on flooding and record rain.
UNSW experts are available to comment on the recently announced third La Niña in as many years.
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.
UNSW has a range of experts available to comment on La Niña.
With La Niña prolonging the wet season, there is an increased risk of flooding along the north, east and southeast regions.
The coming El Niño and La Niña double bill could be the strongest since 1998, affecting a vast swathe of the planet from Africa, through Australasia and all the way to the Americas, write Wenju Cai, Agus Santoso and Guojian Wang.
When a positive Indian Ocean dipole is coupled with an El Niño event, rainfall decreases dramatically across Australia, and such an event could be on the way, write Agus Santoso and Wenju Cai.
It is only May and summer is seven months away, but climate researchers are seeing the beginnings of what could be the most powerful El Niño event in close to two decades.
