"In the past few years in Australia, seasonal rainfall and temperatures have
left a lot of people confused. Sometimes, the hot, dry conditions usually
associated with an El Niño have not eventuated. Similarly, there have been
years where a La Niña did not lead to the cool, wet conditions expected.
It’s important for scientists to better understand all weather processes at
play, so we can manage expectations around what Australia might experience when
climate drivers such as El Niño and La Niña are forecast in future. That’s
where our new research comes in.
We examined the state of play in November 2020 and November 2021. La Niña
conditions occurred in both years. November 2021 followed the La Niña script
and was wet and cool, but November 2020 departed from expectations and was dry
and warm. We set out to determine why.
We found the differences could be explained by fluctuations in the path of
storms over the Australian continent. These fluctuations can be hard to predict
well in advance, which makes it difficult to say for certain how a particular
La Niña or El Niño event will affect Australia."
