The cyclone formerly known as Oswald

Tropical Cyclone Oswald hit the coast of Queensland in January 2013 and headed south as  an “ex-tropical cyclone”, causing havoc and heartache for a considerable length of time.

Three images sent to me by artist Adrienne Williams once again reminded me of the power of water at such times. Adrienne lives at Mount Perry, south-west of Bundaberg — an area hit particularly hard by wind and rain.

These photos show the minor pot-holes created in the three roads linking Adrienne’s home to the rest of the world after ‘ex-cyclone’ Oswald passed by. They received 600 mm of rain in 72 hours. That’s Sunday, the ‘50% Lab 50% Rotti’ casting a cool eye over the scene. All photos courtesy (and copyright) Adrienne Williams.

It’s difficult to find one site on the web that gives an overview of the history and impact of this particular cyclone. It’s just all too big. The strength of nature when things gets fired up is expressed instead at a local level in images like these from Adrienne.

The Australian Bureau of Meteorology (BOM) website states that “Although the considerable majority of cyclone impacts are located in north Queensland, occasionally a cyclone affects areas further south down the east coast.” Oswald certainly fell into that category, even reaching Sydney eventually.

If you’re after some great stuff on cyclones, the BOM site has a stack of fascinating information on these things in Australia, including the following snippets on Queensland cyclones:

  • There have been 207 known impacts from tropical cyclones along the east coast since 1858. Australia’s deadliest tropical cyclone occurred on 4 March 1899 when a cyclone hit a pearling fleet in Bathurst Bay (north of Cooktown) and caused a massive storm surge accounting for 307 known fatalities.
  • On average 4.7 tropical cyclones per year affect the Queensland Tropical Cyclone Warning Centre Area of Responsibility. There is a strong relationship with eastern Australian tropical cyclone impacts and the El Niño-Southern Oscillation phenomenon, with almost twice as many impacts during La Niña than during El Niño. The likelihood of this occurring by pure chance is remote (significant at 99% level).
  •  The Queensland region of the Gulf of Carpentaria region has been hit by several disastrous tropical cyclones. These include The 1887 Burketown cyclone, The 1923 Douglas Mawson cyclone, The 1936 Mornington Island cyclone; the 1948 Bentick Island cyclone and Ted in 1976.
