Why are they called cyclones and not hurricanes - out of interest?

I've been in a hurricane before but not a cyclone. I presume they are the same thing?

The name of the storm system varies according to the place of origin of these storms.

Cyclones - Storms are called cyclones if they are formed over the Indian Ocean and Southwestern Pacific Ocean i.e. near Africa and Australia.

Typhoon - Storms are called typhoons if they are formed in the Northwestern Pacific Ocean i.e. near Asia.

Hurricane - Storms are referred to as hurricanes if formed in Atlantic Ocean and Eastern Pacific Ocean i.e., near Gulf of Mexico and America.

Phil is correct!

Another difference, is that Cyclones rotate clockwise in the Southern hemisphere, whilst Hurricanes rotate anti-clockwise in the Northern hemisphere.

No. They are all cyclones - whether in the northern or southern hemispheres. Hurricanes and typhoons are still cyclones (technically it doesn't work the other way). "Cyclone" is the scientific term for any circular, rotating storm no matter where it occurs. Hurricane and Typhoon are just regional terms for a cyclone - not actual scientific terms.

Ok, you are both correct!

Yasi looms large over tiny Tracy

Cameron Atfield
February 1, 2011 - 9:51PM

Cyclone Yasi's size and power will dwarf Cyclone Tracy, the most devastating storm in Australian history, and could cause even more widespread destruction.

http://images.brisbanetimes.com.au/file/2011/02/01/2162000/cyclone-anim-article....

Weatherzone meteorologist Brett Dutschke said Cyclone Yasi was the largest cyclone he had ever observed in Australian waters on satellite images.

"The area that it's covering is massive and to see it so close to Australia, even 1000 kilometres away, is a bit haunting," he said.

"It's definitely something I've not seen before."

And Yasi made Cyclone Tracy - the storm that destroyed Darwin in 1974 - pale in comparison.

"It's a huge contrast to Tracy. Tracy was a much smaller cyclone, a lot more compact and it just happened to pass directly over a major populated area," Mr Dutschke said.

"[Tracy] was a similar intensity to this one, but Yasi is much larger so it probably only has to get within a few hundred kilometres of a populated area and it could cause similar damage.

"It doesn't have to be as choosy as Tracy with its accuracy."

Mr Dutschke said such a severe cyclone was "always on the cards" during the La Nina weather pattern, because ocean surface temperatures were warmer than normal.

And Cyclone Yasi was so powerful, it could remain a cyclone even after it had reached the outback.

"The more intense they are when they make landfall, the further they need to go [inland] before they are no longer a cyclone," Mr Dutschke said.

"It's probably going to have to go 500 kilometres inland before it's no longer of a cyclone intensity.

"It can effectively be desert that far inland."

Once it reaches landfall, Yasi is expected to follow Cyclone Anthony's lead and head southwest.

Mr Dutschke said the effects of Yasi could be felt as far away as Adelaide.

"It will bring a lot of moisture and there's a reasonable chance for flooding along the Murray [River]," he said.

As can be seen from the comparisons, Yasi is much closer to a Katrina, than the other large Australian cyclones of the last 30-40 years.

Now, perhaps there are good arguments as to why these recent Global weather events of the last 10 years are not related to Climate Change, but it sure as hell looks like something is changin and its not just the times that area changin!

TROPICAL Cyclone Yasi has been upgraded to a life-threatening category five storm with wind gusts of up to 280km/hr expected in some areas.

The Bureau of Meteorology this morning described Cyclone Yasi as a large and very powerful tropical cyclone that poses an "extremely serious threat to life and property" within the warning area, particularly between Port Douglas and Townsville in Far North Queensland.

Meteorologists expect the impact of Cyclone Yasi to be "more life threatening than any experienced during recent generations."

The cyclone is expected to move in a west-southwesterly direction today, with an 'extremely dangerous' storm tide expected between Port Douglas and Townsville as the cyclone crosses the coast.

Residents in the cyclone warning regions are encouraged to protect property and evacuate as strong currents, giant waves and flooding of low-lying areas is anticipated.

Winds with gusts of up to 90 km/hr are expected on the coastal islands this morning, before moving on to the coast later today and further inland overnight.

The wind gusts are expected to reach in excess of 125km/h this afternoon between Cooktown and Ingham, and up to 280km/h tonight between Port Douglas and Cardwell.

SCARY CYCLONE!!!!!!
280KM/H WINDS Wheeeeew that would blow your wig off!

What I'm REALLY dreading is Anna Bligh standing side by side with the chief of the SES, giving their 2 hourly updates.....repeat of the floods. They started last night, repeating what we'd already heard on the news broadcast. She must be revelling in this, being shown in a good light twice in a matter of weeks. Doesn't she get paid too much to be a news reporter? Any random reporter could easily give us the updates, while she gets on with the job of selling qld, although she won't get much now, damaged goods and all.....fire sale!

Here it comes ... Cairns prepares for the worst

Yasi has been upgraded to a category five - the most severe form
- and its impact is now ''likely to be more life-threatening than any experienced during recent generations'', the Bureau of Meteorology says.

Yasi was upgraded overnight and at 4am today was about 650 kilometres east northeast of Cairns and 650 kilometres northeast of Townsville, moving southwest at 30 kilometres an hour.

With Cairns directly in Yasi's path, retailers yesterday reported that many people were stocking up on supplies ahead of the potentially devastating cyclone.

Hospitals evacuated
More than 250 patients were flown from Cairns to Brisbane last night as authorities evacuated two hospitals ahead of the arrival of Yasi.

Ms Bligh said 11 aircraft from the Australian Defence Force, Royal Flying Doctor Service and the government air wing were used to carry patients who had been at the waterfront Cairns Base and Cairns Private hospitals.

===============
This storm is so large that it will hit a populated area, no matter where it crosses the coast.

Without wishing it to hit anywhere, I hope the eye of the storm diverts away from directly impacting on Cairns, as that would expose the largest population centre in that area.

I would also hope that the state & Federal government have contingency plans in place, for the army, airforce & all available personnel to be ready to move in, as soon as the situation becomes clear, once the cyclone has crossed the coast, because if Yasi stays around category 4-5, they will be needed.

We haven't seen a decent La Nina for the last 10 -12 years either.

We packed the fridge with beer and dragged in the patio furnuture and now we're gonna just wait it out.

Stay safe North and Far North QLD

Yes perce....Anna reckons she's got it under control, as long as it doesn't blow away too many of her assets ha ha

The trouble with a cyclone this size is that so many have to stay put and bunker down, just too many people to move, and where would they all go? the cyclone covers such a huge area. Don't wish for it to come further south, maybe up higher will be better.

You would do well to listen to your wife more andrei.

........

“The cyclone has now reached category five and will continue to move in a west-southwesterly direction during today,” the BoM said on its website.

Coastal residents, particularly between Port Douglas and Townsville, were being warned of an “extremely dangerous” storm tide as the cyclone approaches and crosses the coast. It is likely to cause flooding some way inland.

I agree Nichy, Andrei would do well to listen to his wife, as the following picture shows.

In fact, Andrei would do well to listen a bit more to others, in general, he may gain some different perspectives.
