Experiment:Severe Thunderstorms and Cyclones

Matt Townsend · Unread post by **Matt Townsend** » Sun 11/06/2006 00:24

There is huge difference between severe thunderstorms and cyclones because of rotations and directions. In my knowledge, severe thunderstorms can cause alot more damage to cyclones because of different changes of wind direction (rotations) and small space of wind burst. As in mircoburst case, small space of strongest wind speed (might be 200km/hr) and around 2km down the road, the weather station recorded 105km/hr wind gust. So i confirmed that severe thunderstorms can uproot a tree far alot more quicker than cyclones because of two reasons:
Rotations
Stronger wind speeds

Anyway, a severe thunderstorm is smaller than cyclones but it more dangerous because of there could be a tornado. I have couple experiments of my past thunderstorm events, using:
Measurement of the area
Observations
Damage
Location of objects (past and present)
Researching

My result of the experiments will be out soon as possible.

I don't think so Matt

A cyclone covers a wider area therefore destruction to trees would come greater than to a severe thunderstorm which is only localised.
Even if coastal parts only experiecned category 4 winds over 250kmh other parts like inland areas would see winds lower but enough for destruction.
You are also far more likly to run away from a severe thunderstorm than you are from a cyclone.
I would believe it would be hard to compare winds from a tornado as to winds from a cyclone because tornado winds vary all the time I mean are you really going to stand under a tornado and get the life sucked out of you just to get a wind reading

.
My theory is that both cyclones and severe thunderstorms should both have the same amount of windspeeds sometimes and that you are more likly to get stronger winds within a cyclone occurance as to a severe thunderstorm.
Cheers

You forgetting something, mircobursts! It have a small space of strength, it can also uproot a tree far quicker.

I am not taking any arguements in this topic. I am taking it seriously. You shouldn't be sarcasm at all, you at look yourself, you done wrong so prove that.

Result 1: 17th December 2005

A tornado like storm roared through my dads place in north Lismore, there is several reports of tennis ball sized hailstones and wind gusts up to 150km/hr by the obs. My report is here: http://www.freewebs.com/mattweather/17t ... er2005.htm

Anyway, i researched about that storm, the wind has changed 3 different directions during the core that is called rotation. I have drew a diagram of my dad place with a drawing of wind directions and a doormat. Sorry i can't post it here because it too small to see the whole image.

It shows wind direction blows eastward in the north side of the house and it picked up my doormat and swing around and around the house 4 times. I comfirmed several tree branches and twigs was some where else which found in our front garden and around the back of the house. Our next door neighbour said there was a lowing cloud whirring over our house while the storm came over, they saw several debris hang around the place. They not sure there was a tornado in the area though.

Matt
A cyclone is made of severe thunderstorms and all they deliver,except the hail part, and can spawn tornadoes, espeicaly when the cyclone makes landfall

and as jaestream said, a cyclone has a relatively large area of destructive winds, often stronger than you can get with microbursts, near the eye of the cyclone

No comment you stick with your theory Matt and we will stick with ours.

Cheers

What that roll eyes for?

Anyway, severe thunderstorms have hail which is not likely in cyclones. So that is more heavier to cyclones.

actually a question has there ever been hail in a tropical cyclone as crazy as this question may sound??

Manukau heads obs · Mon 12/06/2006 22:31

i doubt it
a TC is a heat based system....in the tropics, over warm water
i.e lots of warmth in the atmosphere

whereas a hail producing severe thunderstorm will have a upper level very cold pool of air , which is where the hail is formed.....its that upper level cold air that creates the instability and formed the thunderstorm in the first place...i.e they go hand and hand......different mechanisms and starting fuels when comparing the thunderstorms in the TC...although the CB tops in a TC will still be reaching well below freezing, and so there will be hail/snow in them....and hail has been reported in the tropics before....
thats my 2 cents worth...

cheers for that, i lived near cairns for 15 months and once we had golf ball sized hail so yes you can get hail in the tropics.
