Hi
I'm here to update my blog, I haven't updated it for a while because of that I haven't found something interesting to talk about. So today I will continues my Weather School with something that many thinks is interesting, Twister or more commonly named Tornadoes.
A tornado is a rapidly rotating column of air, which is contact with the ground. This rotationg column needs to have a suiffcient rotating before its called a tornado. If you have a tornado you should have a convective (strong upward winds) storm in the vincinity, either it's hanging from or positioned beneath the base of the cloud. It's the atmospheric pressure who defines how the tornado looks like and the damaging wind is extended outsided the outline of the 'tornado cloud'. Even if we doesn't got any cloud, we still can have a strong wind.
How a tornado really does work is hard to know, but they are still pretty amazing and beutifull. Something interesting is that the updraft in a tornado is many times stronger then the graviation accelration which implis tha we got strong pressure difference vertically.
Like usally please comment and give me your thought about this entry.
