What does the hurricane category scale measure?
The hurricane category scale has evolved over time, but in its current version, it only measures the wind speeds produced by a hurricane. This means the different hurricane category designations won’t tell you about the flooding or tornadoes that might accompany hurricanes, but they can give you a sense of how strong a hurricane might be and what kind of threat they present.
How often do tropical storms occur?
It is typical for these disturbances to emerge from the African coast approximately every 3 to 4 days (between June 1 and November 30, the time period of the hurricane season.) They begin as tropical waves that come from areas of unsettled weather. It is also possible for a tropical cyclone to be formed from the trailing end of a cold front, or from an upper level low system.
What is the wind speed of a hurricane?
At the point when the storm reaches sustained wind speeds of 74 mph or greater , it is officially classified as a hurricane. Air at the center of the storm sinks rapidly, drying and warming the area. This cloud free area is the eye of the storm.
What are the conditions needed for a tropical cyclone to form?
1.) A preexisting disturbance that also contains thunderstorms. 2.) Warm ocean temperatures that are at least 80 degrees from the surface to a depth of 150 feet. 3.)
What is the maximum sustained speed of a tropical depression?
There is also a well defined surface circulation of the wind whose maximum sustained speed is 38 mph or less.
Why do people not realize that a hurricane is imminent?
People often fail to realize that a storm is imminent because the eye makes landfall before the most intense part of the storm. They sometimes even mistakenly believe that they aren’t going to be hit by the most intense part of the storm because the eye makes landfall at a specific place before the most intense parts of the storm set in. A hurricane can have a life span of more than two weeks while it is in the ocean. It can also potentially travel up the entire Atlantic coast.
What is the most severe meteorological phenomenon?
The NOAA (National Oceanic and Atmospheric Administration,) tells us that hurricanes are the most severe of meteorological phenomena. They are essentially tropical cyclones that form from low pressure systems that rotate in a counter clockwise motion. They are accompanied by thunderstorms.

A Category 4 hurricane will have wind speeds between 131 – 155mph, and can cause a storm surge between 13 – 18 feet high. This will completely destroy mobile homes, and other small structures, and will generally cause wide spread flooding.
What happens when a tropical storm turns into a hurricane?
As the air pressure continues to drop, and wind speeds reach and exceed 74mph , a tropical storm officially becomes a hurricane. At this point the intense rotation of the winds will cause a central eye to form at the centre of the storm, which will be clearly visible from satellite images. The walls of the eye carry the highest winds and rainfall.
What is the intensity of a hurricane?
As a hurricane continues to form and grow, its intensity is measured on the Saffir-Simpson scale, which gives hurricanes a rating between 1 and 5.
What is a hurricane?
Hurricanes are intense tropical storms that form in warm moist air. However, they don’t appear out of nowhere. A storm must go through several stages of development before it can be classed as a hurricane force storm.
How does a hurricane become stronger?
Once a hurricane is formed, it takes more energy from the warm ocean water to become stronger. A hurricane will strengthen if there is a supply of warm, moist air to feed it.
How fast does a thunderstorm wind?
At this point wind speeds are in the range of 23 to 39 mph. As the thunder storms release heat, this warms the disturbance. This causes the air density inside the storm to lower, which in turn leads to a dropping of the air pressure.
Why does wind speed increase in a hurricane?
Wind speeds increase as cooler air rushes underneath the rising warm air. As this wind is subject to the Coriolis force, the storm begins to rotate.

What is a hurricane cycle?
Most hurricanes follow a similar cycle of development, called a hurricane life cycle. These life cycles may run their course in as little as a day or last as long as a month. All hurricanes begin as an area of low pressure in the atmosphere, where surface winds are converging toward each other.
How are hurricanes formed step by step?
Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form.
How many categories of hurricanes are there?
There are five types, or categories, of hurricanes. The scale of categories is called the Saffir-Simpson Hurricane Scale. The categories are based on wind speed.
What happens during a hurricane?
When a hurricane strikes a coastal area, it brings a number of serious hazards. These hazards include heavy rains, high winds, a storm surge, and even tornadoes. Storm surge pushes seawater on shore during a hurricane, flooding towns near the coast. Heavy rains cause flooding in inland places as well.
Where do hurricanes first start?
Hurricanes begin as tropical storms over the warm moist waters of the Atlantic and Pacific Oceans near the equator. (Near the Phillippines and the China Sea, hurricanes are called typhoons.) As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere.
