Saffir simpson wind scale

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 saffir simpson wind scale not devastated in the same way as the Caribbean Islands.

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane's sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. Category 1 and 2 storms are still dangerous, however, and require preventative measures. In the western North Pacific, the term "super typhoon" is used for tropical cyclones with sustained winds exceeding mph.

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 separates hurricanes into five different categories based on wind. The U. National Hurricane Center classifies hurricanes of Category 3 and above as major hurricanes, and the Joint Typhoon Warning Center JTWS classifies typhoons of mph or greater strong Category 4 and Category 5 as super typhoons although all tropical cyclones can be very dangerous. Most weather agencies use the definition for sustained winds recommended by the World Meteorological Organization WMO , which specifies measuring winds at a height of 33 ft By contrast, the U. National Weather Service, Central Pacific Hurricane Center and the Joint Typhoon Warning Center define sustained winds as average winds over a period of one minute, measured at the same 33 ft When far out to sea, the winds are estimated using satellite imagery. When closer to land, so-called "hurricane hunter" aircraft provide more accurate estimates. The scale is roughly logarithmic, like the Richter Scale for earthquakes. A typical Category 2 storm could produce 10 times the damage of a typical Category 1 because wind power or force increases exponentially with increases in wind speed and therefore, so does potential damage. The original Saffir-Simpson Hurricane Scale included central pressure and storm surge. Pressure information is now considered superfluous for the public. Storm surge, although related to wind speed, is affected by too many other factors to be a direct relationship. For storms that make land fall, there will be separate predictions and warnings about storm surge and other storm-related threats including rain-produced flooding and tornadoes which are not related at all to storm intensity.

Major hurricanes can cause devastating to catastrophic wind damage and significant loss of life simply due to the strength of their winds. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days, saffir simpson wind scale. High winds will cause devastating damage.

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.

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. Major hurricanes can cause devastating to catastrophic wind damage and significant loss of life simply due to the strength of their winds. Hurricanes of all categories can produce deadly storm surge, rain-induced floods, and tornadoes. These hazards require people to take protective action, including evacuating from areas vulnerable to storm surge. Disclaimer Information Quality Help Glossary.

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.

Archived from the original on December 14, Category 4 storms may cause catastrophic damage. The scale separates hurricanes into five different categories based on wind. Content control:. A large number of trees are uprooted or snapped, isolating many areas. Safety knowledge contributed by:. Current Hazards. Earth Science, Climatology, Meteorology. Fallen trees and power poles will isolate residential areas. The U. Power outages will last for weeks to possibly months.

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 Galveston hurricane , the deadliest natural disaster to hit the United States, peaked at an intensity that corresponds to a modern-day Category 4 storm. Unless most of these requirements are met, the catastrophic destruction of a structure may occur. Archived from the original on May 19, A home in Fort Lauderdale experiences strong winds and flooding from Hurricane Irma. Power outages could last anywhere between several days to weeks. Large branches of trees will snap and shallowly rooted trees may be toppled. Multiple locations were found. Accessed March 9, Customize Your Weather. Article Talk. Bibcode : EOSTr.. These storms cause complete roof failure on many residences and industrial buildings, and some complete building failures with small utility buildings blown over or away. Near-total to total power loss is likely for up to several weeks and water will likely also be lost or contaminated. Collapse of many wide-span roofs and walls, especially those with no interior supports, is common.
