Warming Temperatures of Antarctic Causing Droughts in Australia, Not Climate Change

Predictive capabilities of Bureau of Meteorology (BOM), has recently made it possible for Australia to have an understanding of what is causing the dry weather and the increasing number of droughts in the country. And the reason here, as per reports cannot be accorded to climate change.

Australia’s rainfall outlook may be affected and will suffer more absence due to a phenomenon a few kilometers above the South Pole. The higher echelons of Antarctica are getting warmer by 40 degrees Celsius as per the latest news on the front. This rarity is called Sudden Stratospheric Warming (SSW).

It is the SSW causing the droughts and warmer climates in Australia, as opposed to the commonly suspected inflictor climate change states the report. The Bureau of Meteorology’s Harry Hendon warned of dry weather ahead. “We will typically see conditions across most of Australia, but primarily concentrated in the eastern part of Australia, become warmer and drier through spring and into early summer,” Dr. Hendon said.

2002, recorded as one of the driest times in Australia, was also a resultant effect of the SSW. The report further clarifies that SSW is a natural occurrence, with no relation to climate change.

Antarctic temperatures have a strong bearing on Australian weather. SSW over Antarctica moves the westerly winds south of Australia to change course further north, pattern meteorologists refer to as a ‘negative SAM’. During warmer weather, this negative SAM pattern brings drier, hotter air into southern Queensland and New South Wales.

“Unfortunately, these are areas already in drought,” said a lead author of the BOM’s spring climate outlook, Andrew Watkins. “This has certainly been a big factor in why winter has been so dry in virtually all of Australia,” he said.
