The BoM mentioned that whereas an El Niño is prone to be declared within the coming weeks, atmospheric circumstances have not but met the factors for the phenomena.
“In terms of El Niño, the Bureau continues to hold El Nino at alert status,” Dr Karl Braganza, the BoM’s nationwide supervisor of local weather providers, mentioned.
“So we haven’t declared an event yet, and that is largely due to the fact that the atmosphere hasn’t quite coupled or reinforced the pattern that we see in the ocean that’s typical of an El Niño event.
“So circumstances are nonetheless impartial within the environment, and we’ll look ahead to these circumstances to lock in earlier than we declare an occasion.”
However, Braganza said hot and dry conditions are nonetheless on the way for Australia, adding that the current record-breaking heat across the globe is putting the planet in unprecedented territory – and could worsen over the next year.
“July seems to be like it is going to be the most popular month recorded globally,” he said.
“Sea floor temperatures – so the worldwide oceans – have been heat now since May, they usually’ve been setting information for every of these months.
“Historically, we haven’t seen a situation like this before where we’re going into an El Nino event with record global ocean temperatures.
“Following a typical El Niño cycle, we’d count on these temperatures to maintain warming now till the center of subsequent 12 months.”
Braganza said a reduction in sea ice was a contributing factor to the record-high temperatures.
“Sea ice is at its lowest extent for this time of 12 months ever, going from the satellite tv for pc file again to the late Seventies,” he said.
“So it is nonetheless rising, and usually it grows up till mid-spring, the ocean ice round Antarctica, nevertheless it’s rising at a a lot slower charge.
“We’re missing a chunk of ice about the size of Western Australia at the moment, so it is quite a notable impact on the southern hemisphere’s climate system.”
