This table show us the information about two strong winds . In the following , I am going to make a comparison between the hurricanes and tornadoes.
Despite the fact that there are major differences between these winds let's first consider a few things that they have in common. The first major similarity is that they both are strong and powerful; for example both winds have a high speed. Another similarity is that the two of them can be very destructive.
On the other hand, there are also many important differences between them. The first difference is about the minimum and maximum wind speed. The hurricanes minimum speed is about 74pmh and 155-200pmh maximum speed while the tornadoes have a minimum 40mph and 250-300mph maximum speed. A second difference is the hurricanes are classified on the Saffir-simpson C1-C5 scale, but the tornadoes are classified by the Fujita F0-F5. Another difference is about the duration and where they start. The hurricanes have one week average and they start over warm oceans, whereas the tornadoes only last a few minutes and sometimes hours and they start usually over land. The third difference is about prediction; the hurricanes can be predicted 2-3 days in advance for a wide area, but tornadoes can be only predicted minutes before they hits.
All in all, the differences outweigh the similarities. They have a strong distinct relationship in terms of mass destruction. Also, tornadoes are less predictable and last for a shorter period of time.
