Saffir simpson wind scale

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane's maximum sustained wind speed. This scale does not take into account other potentially deadly hazards such as storm surge, rainfall flooding, and tornadoes.

All hurricanes are dangerous, but some are more so than others. The combination of storm surge, wind, and other factors determine the hurricane's total destructive power. The Saffir-Simpson Hurricane Wind Scale is designed to help determine wind hazards of an approaching hurricane easier for emergency officials. The scale is assigned five categories with Category 1 assigned to a minimal hurricane and Category 5 to a worst case scenario. Categories 3 to 5 are defined as major hurricanes. The criteria for each category are shown below. Past Weather Tropical Cyclone Reports.

The Saffir-Simpson Hurricane Wind Scale is a rating system that classifies hurricanes based on their sustained wind speed. Earth Science, Climatology, Meteorology. A home in Fort Lauderdale experiences strong winds and flooding from Hurricane Irma. South Florida felt some of the force from Hurricane Irma but it was not devastated in the same way as the Caribbean Islands. A hurricane is a tropical cyclone. Tropical cyclones are strong, rotating storms that begin over tropical oceans and bring strong winds and heavy rain. Tropical cyclones in the northwest Pacific Ocean are called typhoons. This includes the Gulf of Mexico and Caribbean Sea. Category three, four, and five hurricanes are major hurricanes and cause the most damage in the U. Yet category one and two hurricanes can still inflict major destruction. One of the deadliest hurricanes in U. Katrina took the lives of more than 1, people. Very dangerous winds will produce some damage. Homes will have roof damage, and large branches of trees will fall to the ground.

Retrieved April 19, Electricity unavailable for weeks.

The Saffir—Simpson hurricane wind scale SSHWS classifies hurricanes —which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms —into five categories distinguished by the intensities of their sustained winds. The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall. The Saffir—Simpson hurricane wind scale is based on the highest wind speed averaged over a one-minute interval 10 m above the surface. Although the scale shows wind speeds in continuous speed ranges, the US National Hurricane Center and the Central Pacific Hurricane Center assign tropical cyclone intensities in 5-knot kn increments e. The Saffir—Simpson hurricane wind scale is used officially only to describe hurricanes that form in the Atlantic Ocean and northern Pacific Ocean east of the International Date Line.

The Saffir—Simpson hurricane wind scale is used officially only to describe hurricanes that form in the Atlantic Ocean and northern Pacific Ocean east of the International Date Line. Other areas use different scales to label these storms, which are called cyclones or typhoons , depending on the area. The scale was developed in by civil engineer Herbert Saffir and meteorologist Robert Simpson , who at the time was director of the U. The scale was created by Herbert Saffir, a structural engineer , who in was commissioned by the United Nations to study low-cost housing in hurricane-prone areas. Mirroring the utility of the Richter magnitude scale for describing earthquakes, he devised a 1—5 scale based on wind speed that showed expected damage to structures.

Tropical cyclones are strong, rotating storms that begin over tropical oceans and bring strong winds and heavy rain. A large number of trees are uprooted or snapped, isolating many areas. Archived from the original on 7 August Hurricanes of all categories can produce deadly storm surge, rain-induced floods, and tornadoes. Power outages will last for weeks to possibly months. Near-total power loss is expected with outages that could last from several days to weeks. The storm's flooding causes major damage to the lower floors of all structures near the shoreline, and many coastal structures can be completely flattened or washed away by the storm surge. Robert Simpson". Many trees uprooted or snapped. Subjects Earth Science, Climatology, Meteorology. Widespread power outages up to several days. It is only used for storms that are stronger than " tropical storms ", and become actual hurricanes. Most of the area will be uninhabitable for weeks or months. Power lines and poles may be damaged, causing power outages that could last between a few and several days. All hurricanes are dangerous, but some are more so than others.

By contrast, the U. Occasionally, suggestions of using even higher wind speeds as the cutoff have been made. Grace in just prior to its Veracruz landfall. National Hurricane Center. Article Vocabulary. Although the scale shows wind speeds in continuous speed ranges, the US National Hurricane Center and the Central Pacific Hurricane Center assign tropical cyclone intensities in 5-knot kn increments e. Most of the area will be uninhabitable for weeks or months. Only a few types of structures are capable of surviving intact, and only if located at least 3 to 5 miles 5 to 8 km inland. Total and long-lived electrical and water losses are to be expected, possibly for many weeks. Simpson explained that "
