Hurricanes and Tornadoes

Natural life contains a lot of things that could be dangerous or beneficial for living creatures. For example hurricanes and tornadoes have the similarities and differences in their characteristics.

Hurricanes and tornadoes have the similarity of minimum wind speed which each is above 40 mph. Maximum wind speeds of most severe storms starts between 155-200 mph in hurricanes and 250-300 mph in tornadoes. Both have classification scale, Suffer- Simpson C1-C5 for hurricanes, Fujita F0-F5. The duration of hurricanes is 1 week average. In the other hand the duration of a tornado is minutes or hours. The Average width of hurricanes is wider than the tornadoes, 300 miles for hurricanes and 100-600 meters for tornadoes. Both can predicted before they happen, in the case of hurricanes it can be predicted 2.3 days in advance for a wide area and 6-10 hours beforehand for a locality. Whereas a tornado taken about 20 minutes or less. Finally the deference between them is the location that they occur. Hurricanes form over warm oceans and tornadoes form usually over land.

In conclusion, tornadoes are less predictable, last for a shorter time, and can reach higher speeds.
