Hurricanes.

You all probably know what a hurricane is. So how does it work? How it forms is a long story. The first thing that happens is that the sun starts to warm the mid-latitude seas. But the warming process has to be so that the water is actually at a temperature of about forty degrees to a depth of atleast seventy metres. As the water heats up, its vapor rises up to form thunderstorms. However the ocasion has to be good enough and the thunderstorms have to be extremely powerfull. And if there are more than a couple thunderstorm forming over an area, there is a lesser chance of the hurricane formation because that set of thunderstorms will dissipate eachother, meaning they will take eachother's energy. And a hurricane is only composed of a small number of thunderstorms which are prety compact in order for sufficient energy storing. So once a super storm has been created, more warm vapour evaporates from the ocean, fueling the storm. And because hurricanes are created near the equatorial line, they start to spin. They spin because as the earth spins, the equator spins faster than the regions that are farther from the equator. So the edges of the hurricane, which are farther from the equator , travel faster than the center of the hurricane, which travels slower. And because of those movement differences between the edges and eye of the storm, the storm or storm cell starts to spin. A hurricane falls into the 'cyclone' category... because it spins. Also the wider the hurricane the faster it will spin due to greater widths and therefore more movement differences are present. A hurricane can spin at an average of three-hundred miles per hour. Bsically all it is,is heavy rains, and that's why a hurricane looks so white. The eye of the hurricane (the centre hole) is the safest place to be as it is clear except for the moderate winds. Why do hurricanes bring so much wind? The answer is because as the hurricane sucks up warm air to stay alive, the colder air drops out of the hurricane and gets pushed away from it. That cold, used-up air that is pushed out is the strong winds. These winds can cause enormous waves on the ocean, usually more than ten metres tall! Anyways, it takes hurricanes almost a week to form, and they can amplify in a twelve-hour course. Once they hit land they can last for a week before dieing down due to lack of warm water which makes up and powers the hurricane. Oh and as the hurricane moves across land, once the eye of the storm is over the land it is safer because as I've said before the eye is a prety calm spot. A hurricane can be about five-hundred kilometres wide (about thre-hundred miles long). Also I forgot to mention previously that the wider a hurricane is the faster it will spin. This is again because the wider the hurricane is there will be a greater movement difference between the centre and edge of hurricane, therefore you get a faster spin. There are also storms very related to hurricanes,such as typhoons. Typhoons are kind of like hurricanes, only they have a much smaller average size. They also have a far weaker average strength, so whereas hurricanes produce the power equivalent to an atomic bomb going off every seccond of the hurricane, typhoons are far weaker and much slower. There are many other cyclonic storms related to hurricanes, some which I don't even have time to state and explain at this moment, maybe later.                                    


Now let's move on to hurricane safety. What should you do? First of all you have to be alert for hurricanes only if you live in areas with a hot anual temperature and a warm ocean. So what you should have in the first place is an effective evacuation plan. And if at home, you should always have some source of media on as an interupting storm warning will alert you. If you're outside you should tune to your cell phone for alerts [some people have that]. A way to predict a hurricane would be a very hot morning and afternoon. These will or might be natural precursors to some thunderstorm activity, and if they are bound to continue for another day, there is a chance that a supercell storm will form, and probably will break into a hurricane. With those precursors you should turn to your nearest source of reliable media. If you see a hurricane watch being posted, you will probably hear your local siren system activate as part of your early warning system. As usual, sirens are activated when watches are posted for extra safety. If you hear your sirens, or any other alert, may it be a watch or warning, you should establish your danger-zone evacuation plan. If you have no time to move out of your community which would be the best thing to do in the first place , you should go to your basement. If no basement, find the middle-most room with no windows and go there. Atleast you'll have a higher chance of surviving. This should be done in any ground-based structure. That's about it for my safety tips.  


 


Here is the hurricane wind speed/damage scale: 1- 119 to 153 km/h (74-95 mph). Minimal damage. 2- 154-177 km/h (96-110 mph). Moderate damage. 3- 178-209 km/h (111-130 mph). Extensive dameage. 4- 210-249 km/h (131-155 mph). Extreme damage. 5- 249+ km/h (155+ mph). Catastrophic damage.

Republicans had to relate to it in some way. THANK YOU, THANK YOU!
