What is the difference between <span title="typhoon/hurricane/tornado/twister/tropical">typhoon/hurricane/tornado...</span> storm/cyclone/tsunami?

Question

How do they grade the levels and what is the highest level e.g level 8 typhoon

Answer 1

Well that&#039;s alot in one question but here it is.

A typhoon/Hurricane/Cyclone are all the same thing. They all are hurricanes and have winds over 74mph.

A tropical storm is just like a hurricane but the winds are from 39mph to 73mph. Its below a hurrricane in strength.

There are only 5 levels on the Hurricane/typhoon/cyclone. This is the saffir simpson scale.(below)

Tropical Storm

Winds 39-73 mph

Category 1 Hurricane — winds 74-95 mph (64-82 kt)

No real damage to buildings. Damage to unanchored mobile homes. Some damage to poorly constructed signs. Also, some coastal flooding and minor pier damage.

- Examples: Irene 1999 and Allison 1995

Category 2 Hurricane — winds 96-110 mph (83-95 kt)

Some damage to building roofs, doors and windows. Considerable damage to mobile homes. Flooding damages piers and small craft in unprotected moorings may break their moorings. Some trees blown down.

- Examples: Bonnie 1998, Georges(FL &amp; LA) 1998 and Gloria 1985

Category 3 Hurricane — winds 111-130 mph (96-113 kt)

Some structural damage to small residences and utility buildings. Large trees blown down. Mobile homes and poorly built signs destroyed. Flooding near the coast destroys smaller structures with larger structures damaged by floating debris. Terrain may be flooded well inland.

- Examples: Keith 2000, Fran 1996, Opal 1995, Alicia 1983 and Betsy 1965

Category 4 Hurricane — winds 131-155 mph (114-135 kt)

More extensive curtainwall failures with some complete roof structure failure on small residences. Major erosion of beach areas. Terrain may be flooded well inland.

- Examples: Hugo 1989 and Donna 1960

Category 5 Hurricane — winds 156 mph and up (135+ kt)

Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. Flooding causes major damage to lower floors of all structures near the shoreline. Massive evacuation of residential areas may be required.

- Examples: Andrew(FL) 1992, Camille 1969 and Labor Day 1935

Getting on to Tornadoes/twisters.

these are the same thing and have nothing to do with hurricanes. Tornadoes can occur in hurricanes but they are not the same thing They are rated on the Fugita Scale EF0, EF1, EF2, EF3, EF4, EF5.

Tsunami&#039;s are not related to either of these things but i think you might be getting storm surge(a rise in sea level along the coastline when a hurricane makes landfall) confused with a tsunami.

Hope this helps!
