Hurricanes and Tornadoes

The table gives us some information about two strong winds. It shows the differences between hurricanes and tornadoes in some features like minimum and maximum wind speed, their classification scale, duration, average width of storm and average number per year…etc.

We can see from the table that the minimum wind speed of tornadoes is 40 mph less than hurricanes at 74 mph. Also the maximum wind speed of tornadoes is higher than hurricanes. It reaches to 250-300 mph. In addition to that we see that the hurricanes last one week. On the other hand, tornadoes last only a few minutes or hours. They use the Saffir-Simpson C1-C5 to scale for the hurricanes and the Fujita F0-F5 to scale the tornadoes. The width of the hurricanes is 300 miles, more than tornadoes at 100-600 meters. Furthermore, the hurricanes start over warm oceans while the tornadoes start over the land. People can predict the hurricanes and tornadoes in advance. The hurricanes can be predicted 2-3 days in advance for a wide area. Also, it can usually be predicted more exactly where it will hit 6-10 hours beforehand. On the other hand, the tornadoes can be predicted only 20 minutes or less.

In conclusion we see that the tornadoes have a higher speed than hurricanes. Also it’s hard to predict the tornadoes. Furthermore hurricanes last longer and affect a larger area than tornadoes.
