Computer screens are measured on the diagonal (from bottom left to top right or vice versa). The most popular size for laptop computers is 15.6. Desktop monitors run larger as you usually sit further away from them. With HDMI you can use a high definition TV set if you want an even bigger view.
Tornadoes are more likely to happen in the spring and summer  because that is when the weather is generally warmest, which leads  to a more unstable atmosphere that can prodâ¦uce thunderstorms and  thus tornadoes.
A tornado begins in a severe thunderstorm called a supercell. A supercell can last longer than a regular thunderstorm. The same property that keeps the storm going also produces most tornadoes. The wind coming into the storm starts to swirl and forms a funnel. The air in the funnel spins faster and faster and creates a very low pressure area which sucks more air (and possibly objects) into it. Tornadoes can form any time during the year, but most form in May. But, more severe ones form earlier because the most damge is caused in April. The more north you go, the later the peak tornado season is. This is because it takes longer to warm the northern parts of the plains so tornadoes form later.
