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: Tornadoes happen when warm, moist air masses and cold, dry air masses collide to cause large thunderstorms. Not all thunderstorms produce tornadoes, and scientists are not certain which factors are directly responsible for their formation. They do know that in many cases, horizontal spinning movements in the air can be lifted vertically.
