According to meteorologists, the air over the Antarctica has hit record icy levels not typical with this time of the year

An extremely cold polar vortex sitting over the Antarctica is likely to have serious effects on Australia’s weather pattern during summer.

According to meteorologists, the air over the Antarctica has hit record icy levels not typical with this time of the year, and this comes in the aftermath of varying weather patterns experienced in several parts of the country in recent weeks.

Besides the ongoing La Nina conditions, this lingering polar vortex is set to deliver above average rains and less extreme heat in the months ahead.

Ben Domensino, a Weatherzone meteorologist noted that the daily weather being witnessed in Australia was being caused by interactions between the low and high pressure systems closer to the Earth’s surface.

As air moves from high-pressured areas to low-pressured regions, the event delivers rainfall and clouds.

Meteorologists are warning that abnormal activities in the Antarctica are affecting these systems, and in turn impacting Australia’s summer.

This stack of cold air is covered by a ring of strong westerly winds forming the polar vortex.

“In a typical year, the polar vortex peaks in winter and breaks down in spring as sunlight returns to the South Pole and the air in the stratosphere warms up,” Mr Domensino said.

“However, this year, the vortex has persisted well into November at an unprecedented strength.”

This is the main reason why peak temperatures have remained below average in most parts of southeastern Australia in the last two weeks.

“There was a particularly cool spell last Thursday, which produced Sydney’s coldest November day in 26 years,” Mr Domensino added.

In conclusion, Mr Domensino stated that though not all regions in Australia have witnessed an increase in wet weather, several areas in eastern NSW had already surpassed the average November rainfall just a third of the days into the month.

While this may signify a wetter summer, he alleged that the strong vortex arriving alongside the La Nina and other major climate drivers was set to stem the impending fire season by bringing in more drought-relieving showers.
