Today I’ll be talking about the hurricane and tornado scales. We’ll go over the hurricane scale, the tornado scale, and how the scales are measured. I hope you learn how to measure hurricanes and tornadoes. After this you’ll be able to tell how much Damage they can do. And I hope you learn a lot from this article.
The scale for tornadoes and hurricanes are the same measured by wind speed. Tornados go from EF0 to EF5. Hurricanes go from a tropical depression that turns into a tropical storm which then goes to category 1 through category 5. Hurricanes can last for around a week, while tornados can only last for at most one hour. Even though tornados can only last for at most an hour but in an hour it can also destroy an entire city.
A tropical depression starts at a wind speed of 32 miles per hour and goes to wind speeds of 39 mph even though 32 mph doesn’t sound bad, It can tip over baby trees. Tropical storms range from 40 mph to 74 mph now can tip a small tree. A category 1 hurricane starts at a wind speed of 75 miles per hour and goes to 95 miles per hour Very dangerous winds will produce some damage to Well-constructed frame homes and could have damage to roof, shingles, vinyl siding and gutters, Large branches of trees will snap and shallowly rooted trees may be toppled, Extensive damage to power lines and poles likely will result in power outages that could last a few to several days. Category 2 starts with a wind speed of 96 miles per hour and can go up to 110 miles per hour Extremely dangerous winds will cause extensive damage to Well-constructed frame homes could sustain major roof and siding damage, Many shallowly rooted trees will be snapped or uprooted and block numerous roads, Near-total power loss is expected with outages that could last from several days to weeks. Category 3 starts at 111 miles per hour and can go up to 129 miles per hour and devastating damage will occur to Well-built framed homes may incur major damage or removal of roof decking and gable ends, Many trees will be snapped or uprooted, blocking numerous roads, Electricity and water will be unavailable for several days to weeks after the storm passes, A category 4 starts at 130 miles per hour and goes up to 156 miles per hour Catastrophic damage will occur to Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls, Most trees will be snapped or uprooted and power poles downed, Fallen trees and power poles will isolate residential areas, Power outages will last weeks to possibly months, Most of the area will be uninhabitable for weeks or months. Category 5 starts at 157 miles per hour and can go anything above Catastrophic damage will occur to a high percentage of framed homes will be destroyed, with total roof failure and wall collapse, Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months, Most of the area will be uninhabitable for weeks or months.
A EF0 tornado starts at a wind speed of 65 miles per hour and goes to 85 miles per hour, causing light damage to some chimneys, branches broken off trees, shallow-rooted trees pushed over, sign boards damaged. An EF1 can reach wind speeds from 86 miles per hour to 110 miles per hour, peeling shingles off of roofs, mobile homes pushed off foundations or overturned, moving autos blown off roads. A EF2 starts at wind speeds of 111 miles per hour and goes up to 135 miles per hour, roofs torn off frame houses, mobile homes demolished, boxcars overturned, large trees snapped or uprooted, light-object missiles generated, cars lifted off ground. An EF3 starts at wind speeds of 136 miles per hour and can get up to 165 miles per hour, causing roofs and some walls to be torn off well-constructed houses, trains overturned, most trees in forest uprooted, heavy cars lifted off the ground and thrown. EF4 tornadoes start at wind speeds of 166 miles per hour and go to 200 miles per hour, causing well-constructed houses to be leveled, structures with weak foundations blown away some distance, cars thrown and large missiles generated. EF5 tornadoes are anything above 200 miles per hour, causing strong frame houses leveled off foundations and swept away, automobile-sized missiles fly through the air in excess of 100 meters (109 yds), trees debarked, incredible phenomena will occur.
I hope you learned more about these natural disasters. Now you know how to prepare. I wrote this article because when my mom told me we could have tornados I got stressed so I decided to learn more about tornados and hurricanes. And now you know about tornados and hurricanes. And I hope you liked the article.
