What is the meaning of Saffir-Simpson scale?
Saffir-Simpson Scale — a rating scale used by hurricane forecasters based on the hurricane’s present intensity. The hurricane’s wind speed is the determining factor in the scale, with category five having the highest and most damaging wind speed and category one having the lowest and least damaging wind speed.
What is the Saffir-Simpson Hurricane Scale used to do?
The Saffir-Simpson Hurricane Wind Scale rates a hurricane’s strength from one to five. A hurricane’s sustained wind speed determines a hurricane’s category. This helps estimate potential property damage along a hurricane’s path.
What is the Saffir-Simpson scale explain four facts about it?
The Saffir-Simpson Hurricane Scale rates hurricanes from category 1 through category 5 in order of increasing intensity. Each intensity category specifies the range of conditions of four criteria: barometric (central) pressure, wind speed, storm surge, and damage potential.
Why is it called the Saffir-Simpson Hurricane Wind Scale?
“Originally, it was designed to describe damage to buildings—it had nothing to do with wind,” Frank says. Simpson assigned each of Saffir’s categories a certain range of wind speed and level of storm surge to make a hybrid scale, called the Saffir-Simpson Hurricane Scale.
What is the Saffir-Simpson scale and who created it?
In the early 1970s, Herbert Saffir, an engineer, and Robert Simpson, a meteorologist, developed a scale to describe the likely effects that hurricanes could have on an area. The scale has five categories, increasing in intensity from 1 to 5. Initially, Saffir and Simpson created the scale based solely on wind speed.
How many categories are on the Saffir-Simpson scale?
The Saffir–Simpson Hurricane Wind Scale (SSHWS), formerly the Saffir–Simpson Hurricane Scale (SSHS), classifies hurricanes – Western Hemisphere tropical cyclones with sustained winds that exceed 63 knots – into five categories distinguished by the intensities of their sustained winds.
What is the difference between Beaufort scale and Saffir-Simpson Hurricane Wind Scale?
1059; List 1984, p. 119). Table 1 shows the Beaufort Scale and includes descriptions of conditions for a given Beaufort force over both land and sea. Saffir-Simpson Scale: The Beaufort Scale classifies all ocean storms with surface-level winds above 32.7 m s-1 as hurricanes.
What is a cat 4 hurricane?
On the Saffir-Simpson Hurricane Wind Scale, a Category 4 hurricane has winds of 130 mph to 156 mph. The video from the National Hurricane Center shows the potential damage of different storm categories. The Saffir-Simpson scale estimates potential property damage.
What is a Category 6 hurricane called?
After the series of powerful storm systems of the 2005 Atlantic hurricane season, as well as after Hurricane Patricia, a few newspaper columnists and scientists brought up the suggestion of introducing Category 6, and they have suggested pegging Category 6 to storms with winds greater than 174 or 180 mph (78 or 80 m/s; …
What does a Saffir-Simpson scale describe?
The Saffir-Simpson scale, also known as SSHWS, is used to classify hurricanes and tropical storms. A tropical cyclone in the western hemisphere that surpasses the limit of tropical storms and depressions is classified as a hurricane. The particular tropical storm must have maximally sustained winds traveling at least between 74-95 miles per hour.
What does the Saffir Simpson scale describe?
What does the Saffir Simpson Scale describe? The Saffir-Simpson Hurricane Scale is a 1-5 rating based on the hurricane’s present intensity. This hurricane scale is used to give an estimate of the potential property damage and flooding expected along the coast from a hurricane landfall.
What scale is used to measure a hurricane?
The Saffir-Simpson Hurricane Wind Scale is the standard used to measure hurricane intensity, and this year, the National Oceanic and Atmospheric Administration (NOAA) is making a modification of the scale. NASA’s Hurricane Web page uses the official NOAA measurements in its tropical cyclone coverage.
What scales are hurricanes measured on?
We measure hurricanes on the Saffir-Simpson scale, which classifies storms from weaker (Category 1) to stronger (Category 5) based on their maximum sustained wind speeds. Some storms are also more intense, reaching wind speeds of over 200 miles per hour.
