With the official end of the Australian tropical season only days away, the calmest season in decades will come to an end.

The season, which officially runs from 1 November through 30 April, has endured only three named cyclones originating within the Australian Tropical Basin.

Having only three named storms of Category 1 strength or higher in the basin would be the fewest dating back to 1970, according to the Australian Bureau of Meteorology (BOM).

According to Senior Meteorologist Jason Nicholls, “El Niño played an important role in the low activity of the tropical season as tropical development flourished closer to Fiji and Vanuatu and away from Australia.” El Niño occurs when ocean water temperatures rise above normal across the central and eastern Pacific, near the equator which influences global weather patterns.

Heavy ice delays Australian Antarctic icebreaker Aurora Australis

“The summer Australian Antarctic Division program will have to be modified because its icebreaker the Aurora Australis has been delayed in heavy ice.

The ship was due to return to Hobart more than a week ago after a resupply mission, but it is still navigating through heavy ice about 180 nautical miles off the Davis research station.’

Less Fresh Water in the Arctic and More Rainfall in Australia Leads To Lower Sea Level and Less Ice?

Could massive amounts of rainfall in Australia have deprived the Arctic of fresh water so there was less sea ice?

NSIDC:  “Water from the Pacific Ocean and several rivers in Russia and Canada provide fresher, less dense water to the Arctic Ocean. So the Arctic Ocean has a layer of cold, fresh water near the surface with warmer, saltier water below. This cold, fresh water layer typically allows more ice growth in the Arctic than the Antarctic.

NCAR: ” when three atmospheric patterns came together over the Indian and Pacific oceans, they drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably.”
