The east coast of Australia is likely to have another wet summer after the Bureau of Meteorology upgraded the likelihood of a La Nina occurring.
BoM meteorologist Hugh McDowell said the last time Australia experienced three consecutive La Nina events was in 1998 to 2001. Since records began, this has happened in Australia only three times.“We are more confident a La Nina could develop,” he said. “It is very rare [for three to occur back-to-back].”
While La Nina causes warmer than average sea temperatures off Australia’s coast which drive storms, it cools downAustralia’s wet weather will linger throughout late winter and spring after a negative Indian Ocean Dipole was declared earlier this month. If a La Nina does occur, it would be the first time on record that we have seen three consecutive La Nina events coinciding with back-to-back negative IOD events.
