2021 has become Australia’s coldest year in nearly a decade after the La Nina phenomenon brought wetter and cooler conditions across the country, the Bureau of Meteorology (BoM) said on Thursday.

The BoM said Xinhua News Agency reports that summary and background information regarding temperature, rainfall and significant weather conditions for the calendar year 2021 show that no large parts of the country experienced rainfall deficits. and drought conditions throughout the year.

For Australia, the average temperature in 2021 was 0.56 degrees above the climate reference period of 1961 to 1990 (average).

It is the 19th hottest year since national records began in 1910 and the coldest year since 2012.

“2021 was almost 0.4 degrees cooler than the average temperature recorded from 2011 to 2020,” said BoM senior climatologist Simon Grainger. It has been much cooler in 2021 than in the past decade. rainfall in 2021 was 9% above average.

“After three years of drought from 2017 to 2019, above-average rainfall last year has resulted in a welcome replenishment of our water supplies, but also significant flooding in eastern Australia,” said Grainger.

Above average rainfall was seen in many parts of the Australian states, causing significant flooding in eastern Australia, particularly in March, November and December.

Grainger explained that the phenomenon was mainly influenced by the impacts of a negative Indian Ocean Dipole, a period of warmer than usual temperatures in the western Indian Ocean, and La Nina, a period of cooling of the central and eastern tropical Pacific Ocean. “Cooler and wetter conditions as a result mean we have continued our recovery from the extreme drought we experienced during 2017-19.”
