~•{ Hurricanes & Tornadoes }•~

Nowadays, the weather is affected by many things like volcanoes and storms. From this table, I will describe the information about two strong winds which are hurricanes and tornadoes.

First of all, the minimum speed of a hurricane is 74 mph, whereas the tornado’s is 40 mph. Next 155 -200 mph is the maximum speed for hurricanes, and 250 – 300 mph for tornadoes. The classification scale for hurricanes is the Saffir – Simpson C1 – C5; however the tornadoes are measured on the Fujuita F0 – F5. On the other hand, the duration of hurricanes is 1 week average, but tornadoes mostly only last a few minutes, some up to few hours. Another point is average width of storm; Hurricanes with 300 miles are more than the tornadoes with 100 – 600 meters. A hurricane can be predicted 2 -3 days in advance but tornadoes only 20 minutes. Finally, the hurricanes start over warm oceans, but the tornadoes start over land.

The outstanding feature of the table is the hurricane with 300 miles in width. However, the tornadoes have more speed with 250 – 300 mph.
