Roaring Forties close Tasmania
The Roaring Forties has long been recognised as a powerful wind force. And that wind carries some of the world’s cleanest air. The Cape Grim Baseline air pollution monitoring station, on the north-west coast of Tasmania, has measured the cleanest air on earth.
But today, volcanic ash from a Chilean volcano is ringing the globe at a latitude of around 40 degrees. While Melbourne airport has re-opened, Tasmania remains closed and New Zealand is next in the path of the ash.
In the old days, Cape Grim was a bain to the early explorers because of its wild seas, ferocious winds and rugged coastline.
Today that wind is captured in a huge windfarm.
During the 1800s, the area was farmed by convict labour and was part of the Van Diemen's Land Agricultural Company property.
An isolated spot but worth a visit.
