Thanks for that update ones again that was very hopefully.

Let hope so need some bit of action that is all I want.

Wont be long Mathew, January could bring some action.
Maybe more than we want, we just have to be patient and be prepared with our kits ready and a general cleanup in the yard.

Thanks for that update that is all I need to know.

Have we ever had a summer with NO cyclones in Australian territory?

1914/15 season no cyclones. I am doing some more research but it would appear that it does occur. But also we have years when cyclones form of the coast and never make landfall too.

according to this there was 3 in 1914/15 one hit fraser island. http://australiasevereweather.com/tropic...al_cyclones.htm

but pretty much a no landfall season.

could u count this season as a no cyclone development season, says they were only depressions. http://australiasevereweather.com/tropic...al_cyclones.htm

Read an article this morning in the sunday mail (Steve Turton from James cook uni), qld due for a super cyclone - cat 5 or cat 6! This guys got a short memory, Yasi was bordering on cat 6 as she was coming in! Hamish was a high cat 5.

BoM Records from 1906 to 2006/07 season total of 860 cyclones
Cyclone Records 1906 to 2007 with track maps in Australian AOR
most active years:
1962/63 season = 19
1973/74 seaon = 19
1983/84 season = 19
1970/71 season = 18
1971/72 seaon = 17

Least
1914/15 season = 0

JCU is he - from what department, gardener, household services, security, Refectory????

Nice media hype. Cat6 - Really? Cat 5 covers winds speed equal to or above 250kph. Can anyone provide a link to the BoM announcement stating that they will now use this as Offical measurements for Australian cyclones?

And we aren't overdue for bloody anything.

I get heartily sick and tired of insurance/actuary terms being used by the useless media to provide OMG content to newspaper 'stories'. It is a term used by actuarries to detremine risk NOT an effort to describe when an event is due to happen.

i.e. 1 in 100 year floods that hit Brisbane in 1974 and in 20011. Now i don't know about anyone elses maths ability but that isn't 1 in 100 years now is it?

So to all you newspaper reporters, TV 'reporters' and other media tarts who read this nforum. Do some dresearch and maybe just maybe you could possibly provide some actual facts in a news story instead of waffle, hype and flat out bullshit.

Yeah,I know facts don't sell newspapers.

Yep no such thing as a cat 6. And Yasi wasn't really a high five. A good five maybe but not in the upper end. Remember it only really gppt down around 929hp

I think I remember reading that Yasi was actually only Cat 4 on the Saffir Simpson scale.

Honestly what are we "overdue" for? We had a once in a lifetime La Nina, once in 30 year flooding across most of the state and a huge Category 5. We just need a cyclone down in SE Qld and that's it.

We may see cyclones stronger than cat 5's, any things possible, but we are not due, we have experienced super cyclones over the last couple of years!

Taken from Wikipedia (for what it is worth).
Officially, the Saffir–Simpson Hurricane Scale is used only to describe hurricanes forming in the Atlantic Ocean and northern Pacific Ocean east of the International Date Line. Other areas use different scales to label these storms, which are called "cyclones" or "typhoons", depending on the area.

And this.....also from Wikipedia:
Some scientists, including Kerry Emanuel and Lakshmi Kantha, have criticized the scale as being too simplistic, indicating that the scale does not take into account the physical size of a storm, nor the amount of precipitation it produces.[7] Additionally, they and others point out that the Saffir-Simpson scale, unlike the Richter scale used to measure earthquakes, is not open-ended, and is quantized into a small number of categories. Proposed replacement classifications include the Hurricane Intensity Index, which is based on the dynamic pressure caused by a storm's winds, and the Hurricane Hazard Index, which bases itself on surface wind speeds, the radius of maximum winds of the storm, and its translational velocity.[12][13] Both of these scales are continuous, akin to the Richter scale;[14] however, neither of these scales have been used by officials.

I've found that most of the time they issue cyclone warnings, they issue flood warnings for some areas at the same time. I believe that as long as everyone is aware of how powerful the cyclone actually is, and can make a decision as to whether they'll stay in their homes, or go to a shelter, the scale is serving it's purpose.

Unless we have an outbreak of cat5+ cyclones, I don't think they'd have any motivation to add a cat6 rating. Cat5 means you're pretty much stuffed if you go through the middle of it, what would cat6 mean?

I would hate to think, Things!! Certainly, we don't have buildings up here on the Tablelands that could even withstand Cat 4. However, I know that our Council is having some of the buildings rated by engineers in the liklihood that we get an influx of people from the coastal areas, as what happened during Yasi. Each town up here has been asked to prepare a disaster management plan and we've been instructed to put in scenarios of having "immigrants" to care for - just in case!

Well i do agree with a lot Kerry Emanuel says he is a respected Meteorologist. Also I have believed always that the current scales for tropical systems is incomplete and to simple i had always believed it should be calculated in Size, Wind speed, Speed of the System, Central Pressure and Precipitation.

this thread is for discussing developing systems of interest, the cyclone lounge was set up for this type of discussion. lets take it into that thread.
