- The Saffir-Simpson Wind Scale is a categorical classification of hurricanes based on their wind speed, used by the U.S. government's National Hurricane Center. To qualify as a Category 5 hurricane on the Saffir-Simpson hurricane intensity scale, maximum sustained winds must exceed 155 mph (135 kt).

Nautical & Sailing Terms & Nomenclature To be classified as a hurricane, a tropical cyclone must have maximum sustained winds of at least 74 mph (33 m/s; 64 kn; 119 km/h) (Category 1). The highest classification in the scale, Category 5, is reserved for storms with winds exceeding 156 mph (70 m/s; 136 kn; 251 km/h).fficially, the Saffir–Simpson hurricane wind scale is used only to describe hurricanes forming in the Atlantic Ocean and northern Pacific Ocean east of the International Date Line.

Contents: Hurricane vs Tornado Intensity. Hurricanes are classified into five categories according to the Saffir-Simpson Hurricane Wind Scale. The wind speed and intensity of damage increases as from category 1 to category 5. The scale used for rating the strength of tornadoes is called the Fujita (F), Enhanced Fujita (EF), and TORRO (T) Scale.ntensity.

- Hurricane measurement and classification A hurricane may be classified as category one if they have their usual speeds of up to 74mph. Going up to category five, they may carry extreme speeds and power, with much more destructive ability. Hurricane winds are measured using the Saffir-Simpson Hurricane scale. This scale was first developed in the late 1960s and was further developed in the early 1970s. It uses measurements in pressure, wind speed, storm surge and damage potential to put hurricanes into 5 categories.

How to describe a hurricane? Best Answer: A hurricane is an intense, rotating oceanic weather system that possesses maximum sustained winds exceeding 119 km/hr (74 mph). It forms and intensifies over tropical oceanic regions. Hurricanes are generally smaller than storms in mid-latitudes, typically about 500 km (311 miles) in diameter.

What is a hurricane? A tropical cyclone is a rotating low-pressure weather system that has organized thunderstorms but no fronts (a boundary separating two air masses of different densities). Tropical cyclones with maximum sustained surface winds of less than 39 miles per hour (mph) are called tropical depressions. Those with maximum sustained winds of 39 mph or higher are called tropical storms. When a storm's maximum sustained winds reach 74 mph, it is called a hurricane. The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating, or category, based on a hurricane's maximum sustained winds. The higher the category, the greater the hurricane's potential for property damage.

Ch. 11, 12, 14, 15 Tropical Cyclone Classification. An organized system of clouds and thunderstorms in the tropics with a defined circulation, and maximum sustained winds of 38 mph or less is called a tropical depression. Once a tropical depression has sustained winds of at least 39 mph, it is called a tropical storm..This is when a tropical cyclone is assigned a name. A tropical storm becomes a hurricane when it reaches maximum sustained winds of 74 mph. Hurricanes are classified by their wind speeds using the Saffir-Simpson Scale.nce a tropical depression has sustained winds of at least 39 mph, it is called a tropical storm.. This is when a tropical cyclone is assigned a name. A tropical storm becomes a hurricane when it reaches maximum sustained winds of 74 mph.

What is a hurricane? When a storm's maximum sustained winds reach 74 mph, it is called a hurricane. The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating, or category, based on a hurricane's maximum sustained winds. The higher the category, the greater the hurricane's potential for property damage. Hurricanes originate in the Atlantic basin, which includes the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico, the eastern North Pacific Ocean, and, less frequently, the central North Pacific Ocean.

Tropical cyclone A hurricane or typhoon (sometimes simply referred to as a tropical cyclone, as opposed to a depression or storm) is a system with sustained winds of at least 34 metres per second (66 kn) or 74 miles per hour (119 km/h). hurricane or typhoon (sometimes simply referred to as a tropical cyclone, as opposed to a depression or storm) is a system with sustained winds of at least 34 metres per second (66 kn) or 74 miles per hour (119 km/h).

- A hurricane is a huge storm! It can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph. Each hurricane usually lasts for over a week, moving 10-20 miles per hour over the open ocean.Hurricanes gather heat and energy through contact with warm ocean waters.inds flow outward above the storm allowing the air below to rise. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator. The Coriolis Force is needed to create the spin in the hurricane and it becomes too weak near the equator, so hurricanes can never form there.

Admiral Sir Francis Beaufort The Beaufort Wind Force Scale is a way to measure and describe the wind speed at sea. His scale had thirteen points e.g. calm = (0); storm = (13). In 1838 the British Navy made Beaufort’s Wind Force Scale the standard way to measure wind at sea. His Wind Force Scale was altered when steam ships became more popular than sailing ships.

âWorst hurricaneâ recorded spares Mexico of major damage Patricia was a category 5 hurricane as measured on the 1-5 Saffir-Simpson Hurricane Wind Scale, writes Jude Webber. That means sustained wind speeds of 157 miles per hour (252km per hour) or higher. Patricia saw sustained wind speeds of 325kph (203mph).

How to Measure Tornadoes: The EF Scale The EF Scale. The EF Scale (below) is the standard way to measure tornadoes based on wind damage. The original Fujita Scale (or F Scale) was developed by Dr. Theodore Fujita. All tornadoes, and other severe local windstorms, were assigned a number according to the most intense damage caused by the storm. The enhanced F Scale (EF Scale) was implemented in the United States on February 1, 2007. The EF scale uses three-second wind gust estimates based on a more detailed system for assessing damage, taking into account different building materials. Note: Click on the chart below to enlarge.

The Enhanced Fujita Scale (EF Scale) Weather.gov > Norman, OK > The Enhanced Fujita Scale (EF Scale) The Enhanced Fujita Scale or EF Scale, which became operational on February 1, 2007, is used to assign a tornado a 'rating' based on estimated wind speeds and related damage. When tornado-related damage is surveyed, it is compared to a list of Damage Indicators (DIs) and Degrees of Damage (DoD) which help estimate better the range of wind speeds the tornado likely produced.

Nautical & Sailing Terms & Nomenclature Officially, the Saffir–Simpson hurricane wind scale is used only to describe hurricanes forming 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.he highest classification in the scale, Category 5, is reserved for storms with winds exceeding 156 mph (70 m/s; 136 kn; 251 km/h). The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall.

Nautical & Sailing Terms & Nomenclature In the northern Indian Ocean, they're called severe cyclonic storms.. In the southwestern Indian Ocean, they're just tropical cyclones.. To be classified as a hurricane, typhoon, or cyclone, a storm must reach wind speeds of at least 74 miles per hour (119 kilometers per hour). While the Atlantic hurricane season runs from June 1 through November 30, the typhoon and cyclone seasons follow slightly different patterns.

- In the United States Tropical Cyclones are measured on a scale called the Saffir-Simpson Hurricane Wind Scale. The scale has a 1-5 category range, assigning each category with a range of the strength of the wind speed, as well as the amount of damage and impact that can possibly occur at each increment of intensity.

Strongest Hurricanes: 10 Most Intense Atlantic Hurricanes on Record But since measurements of the most extreme winds are difficult to obtain, we instead compare hurricanes by their lowest central pressure, a measure that has a strong relationship to wind speed; generally, the lower the pressure in a hurricane, the stronger its winds.
