Western Australia, New South Wales, Victoria and South Australia are the territories or states were most tornadoes have been reported. However, tornadoes activities occur in all Australia. There are places were these activities go unnoticed because they’re unoccupied, outback areas.
The season for tornado is from November to February, which I find curious since this is our winter time. :)
Like tornado in the United States, are usually generated from a severe thunderstorm with strong winds, heavy rain and hail. The Fujita Scale is the measure used in Australia to scale the intensity of the tornado.
F0 Gale tornado 40-72 mph: Some damage to chimneys; breaks branches off trees; pushes over shallow-rooted trees.
F1 Moderate tornado 73-112 mph: The lower limit is the beginning of hurricane wind speed; peels surface off roofs; mobile homes pushed off foundations or overturned; moving autos pushed off the roads.
F2 Significant tornado 113-157 mph: Considerable damage. Roofs torn off frame houses; mobile homes demolished; large trees snapped or uprooted; light object missiles generated.
F3 Severe tornado 158-206 mph Roof and some walls torn off well-constructed houses; trains overturned; most trees uprooted.
F4 Devastating tornado 207-260 mph Well-constructed houses leveled; structures with weak foundations blown off some distance; cars thrown and large missiles generated.
F5 Incredible tornado 261-318 mph Strong frame houses lifted off foundations and carried considerable distances to disintegrate; automobile sized missiles fly through the air in excess of 100 meters; steel re-enforced concrete structures badly damaged.
F6 Inconceivable tornado 319-379 mph These winds are very unlikely. The small area of damage they might produce would probably not be recognizable along with the mess produced by F4 and F5 wind that would surround the F6 winds.
Golf size hail that appears in this photo was reported to have fallen on a November 29, 1992 tornado in Brisbane, Queensland of over 200 mph winds. The only thing strong enough that I have felt was hurricane Georges with 115 mph winds and I wanted to die from the sheer terror; the sound of the wind and how it ripped houses and trees around us was scary enough. I can’t imagine how people endured this tornado, that, with only the hail, obliterated brick houses.
This photo shows us the damages that left behind a tornado on a January 22, 1991 tornado in Adelaide, South Australia. $90 millions on damages; the tornado was scaled as a F5. Shivers.
