Named for Huracan, the Carib god of evil, the hurricane is an amazing yet destructive natural phenomenon that occurs about 40 to 50 times worldwide each year. Approximately 90% of all hurricane deaths can be attributed to the storm surge, the dome of water created by the low pressure center of a hurricane. This storm surge quickly floods low-lying coastal areas with anywhere from 3 feet (one meter) for a category one storm to over 19 feet (6 meters) of storm surge for a category five storm. Hundreds of thousands of deaths in countries such as Bangladesh have been caused by the storm surge of cyclones. The strong, at least 74 mph or 119 km/hr, winds of a hurricane can cause widespread destruction far inland of coastal areas, destroying homes, buildings, and infrastructure. Hurricanes are huge tropical storms and dump many inches of rain over a widespread area in a short period of time. This water can engorge rivers and streams, causing hurricane-induced flooding.
The strength of a hurricane is measured by one minutes sustained winds in mph or in knots. These winds fall into the range of one of the 5 categories on the Saffir-Simpson scale.
Category 1: 74-95 mph (64-82 knots)
Category 2: 96-110 mph (83-95 knots)
Category 3: 111-130 mph (96-113 knots)
Category 4: 131-155 mph (114-135 knots)
Category 5: 156+ mph (136+ knots)
Sustained winds in hurricanes have been recorded as high as 190 mph (165 knots).
Hurricanes are measured by the Saffir-Simpson Hurricane Scale.
A hurricane is measured in a damage scale from 1-20 1 being strong enough to knock over a small tree and 20 being able to destroy a hole city.
a hurricane is measured so that meterolgest can approximate the amount of damage that would be done so they would be able to prepare for it
with barometers but on a larger scale
Category 5
They use dropsondes.
Hurricane strength.
Wind speed is the determining factor for the Saffir-Simpson rating (Category 1-5). This can be measure with an anemometer or estimated based on satellite imagery. Another measure of intensity is barometric pressure, which is measure with a barometer.
F5 is not a category used to rate hurricanes, only tornadoes. Category 5 is the strongest category used to rate hurricanes. Atlantic hurricanes.

Such a storm is called a hurricane.
scientists use fajita scale to measure hurricane intensity
Hurricane Irene was a category 3 hurricane. It had weakened to a category 1 by the time it hit the U.S. though.
Meteorologist observe the hurricane in a close distance with it. Maybe in the future there will be a tool which can measure the speed of the hurricane. :)
yes
They use dropsondes.
Hurricane strength.
The Saffir-Simpson scale.
That is highly variable and is in fact a measure of the hurricane's size. The radius of tropical storm force winds in a hurricane can be less than 100 miles, to more than 600 miles.
Wind speed is the determining factor for the Saffir-Simpson rating (Category 1-5). This can be measure with an anemometer or estimated based on satellite imagery. Another measure of intensity is barometric pressure, which is measure with a barometer.
No, Hurricane Sandy is not the strongest hurricane on record. While it was a powerful storm that caused significant damage, there have been other hurricanes that have had higher wind speeds and caused greater destruction. The 1935 Labor Day hurricane and Hurricane Allen in 1980 are examples of storms that were more intense than Sandy.
Like all hurricanes, it was a 12 on the Beaufort Scale. That is as high as the scale goes.
No. The Saffir-Simpson scale is used to rate hurricane strength. Earthquakes are measure on the Moment Magnitude scale (formerly the Richter scale).
