Hurricanes are massive storms with spinning winds. They can generate winds of up to 119 kilometres per hour (74 miles per hour). That’s faster than the fastest land mammal, the cheetah. A hurricane’s winds can cause damage to houses and trees.Over warm ocean waters, hurricanes form. They occasionally make contact with the ground. When a hurricane hits land, it sends a wall of water crashing ashore. A storm surge is the name for this wall of water. Flooding can occur as a result of heavy rain and storm surge from a hurricane. Hurricanes are classified into five sorts or categories. The Saffir- Simpson Hurricane Scale is a classification system. The wind speed determines the groups.
Winds ranging from 119 to 153 km/h (74-95 mph) – quicker than a cheetah. Winds of 154-177 km/h (96-110 mph) – as fast as or quicker than a baseball pitcher’s fastball. Winds ranging from 178 to 208 km/h (111 to 129 mph) – equivalent to, or close to, the serving speed of many professional tennis players. Winds gusting to 209-251 km/hr (130-156 mph), which is quicker than the world’s fastest rollercoaster.
Winds exceeding 252 km/hr (157 mph) – comparable to, or near to, the speed of some high-speed trains Weather forecasters anticipate the path of a cyclone once it has formed. They also forecast how powerful it will become. People can use this information to prepare for the storm. What Are the Different Components of a Hurricane?
The “hole” at the centre of the storm is known as the eye. In this area, the winds are light. The sky is partially hazy and occasionally clear. The eye wall is a ring of thunderstorms that surrounds you. The eye is surrounded by storms. Winds are fiercest and rain is heaviest along the wall.
Rain bands: Cloud and rain bands extend far beyond a hurricane’s eye wall. Hundreds of miles separate these groupings. Thunderstorms and tornadoes are common in these areas. What Happens When a Storm Turns into a Hurricane? A tropical disturbance is the precursor to a hurricane. Rain clouds are forming over warm ocean waters in this area.
Occasionally, a tropical disturbance develops into a tropical depression. This is a rotating thunderstorm area with winds of less than 62 km/hr (38 mph). When the winds of a tropical depression reach 63 km/hr, it becomes a tropical storm (39 mph).If the winds of a tropical storm reach 119 km/hr, it becomes a hurricane (74 mph). Hurricanes are formed by a combination of factors.
Scientists are baffled as to why or how hurricanes arise. However, they are aware that two key elements are required. Warm water is one of the ingredients. Warm ocean waters supply the energy required for a storm to develop into a hurricane. For a hurricane to form, the surface water temperature must be at least 26 degrees Celsius (79 degrees Fahrenheit).
Winds that don’t fluctuate significantly in speed or direction as they rise in the sky are another element. Storms can be ripped apart by winds that fluctuate dramatically with height. How Do Hurricanes Get Their Names? At any given time, there may be many hurricanes. One of the reasons hurricanes are given names is because of this. Storms are easier to track and discuss when they have names.
If a storm becomes a tropical storm, it is given a name. If the storm develops into a hurricane, the name will be kept. (There are no names for tropical disturbances and depressions.) Tropical storms are named in alphabetical order each year. The names are drawn from a list of names for that particular year. There are six names listed. Every six years, the lists are updated. If a storm causes significant damage, its name may be removed from the list. The old name is then replaced with a new one that begins with the same letter.
The lists of names can be found here. What Methods Does NASA Use to Research Hurricanes?
Hurricanes are photographed from space by NASA satellites. These images are broadcast on television. They are also available to view on the internet.Cloud and ocean temperatures are measured by some satellite equipment. Others gauge the height of clouds and the rate at which rain falls. Others measure the wind’s speed and direction.
To understand more about hurricanes, NASA scientists use data from satellites and other sources. They can use the data to learn more about how hurricanes form and grow stronger. The information also aids hurricane forecasters in predicting the route and strength of storms.
Did you realise that African dust storms can have an impact on hurricanes? Scientists can use a technology on two NASA satellites to analyse how dust affects hurricanes.
NASA also sends planes into hurricanes and above them. The onboard instruments collect information about the storm. People should not fly into some regions of a cyclone because they are too dangerous. To study these parts, NASA uses airplanes that operate without people.
NASA also carries out special projects to learn more about hurricanes. These projects use a mix of instruments on satellites, on aircraft and on the ground.
