How do tornadoes and hurricanes have a similar effect

they both contain strong rotating winds which can cause damage.

Tornadoes and hurricanes may be similar in that they both have extreme winds circulating around a their center that can cause damage. That’s just about where the similarities end.

Tornadoes, are defined by the National Weather Service as:
“A violently rotating column of air, usually pendant to a cumulonimbus, with circulation reaching the ground. It nearly always starts as a funnel cloud and may be accompanied by a loud roaring noise. On a local scale, it is the most destructive of all atmospheric phenomena.” Winds in the strongest tornadoes can top 300 mph.

Hurricanes are powerful storms that develop in a circular pattern over warm ocean waters. Hurricane winds are 74 mph or faster with category 5 hurricanes producing winds of 157 mph or higher. This year we witnessed hurricane Irma which is one of the strongest hurricanes on record produce winds of 185 mph.

There was a group of young european workers that came to America from early 17th to early 20th century. These inmigrants would get a contract to work for an american employer during a time period, usually between 1 to 7 years. They didn't get any wages for their work, the employer paid for their subsistance and their passage to the country, but that also meant that he could restrict some of their activities, they weren't completely free. After their contract expired, they were allowed to stay in the country and sometimes they would get a small parcel of land. They were called the Indentured servitude.
