Kids usually get curious about hurricanes. They usually have many questions about them. What are hurricanes? How do they form? What are the most famous hurricanes? Where can hurricanes be found? What is the biggest hurricane?
Many articles and videos introduce really useful information about hurricanes for kids. One of the most interesting ways for kids to be taught about hurricanes is through activities. When they make projects about hurricanes, they understand them better.
A hurricane is a kind of a giant storm that results in heavy rainfalls. There are some reasons why hurricanes form. Some changes happen during hurricanes. Hurricanes have damaging effects. In this article, we introduce almost all the information about hurricanes.
What is a Hurricane?
A hurricane is a huge rotating storm with strong winds at speeds of 75 to 200 mph that forms over warm waters in tropical areas. They usually form in the sea. The word hurricane goes back to “Huracan,” the name of a Mayan god. It is the god of big winds and evil spirits.
Hurricane season starts from the beginning of June till the end of November. Mid-September is considered the peak of the hurricane season. Coastal zones are most prone to the dangers of hurricanes. In addition to this, each hurricane lasts for over a week.
Hurricanes have different names according to their locations. In North America and the Caribbean, hurricanes are called hurricanes. In the Indian Ocean, hurricanes are given the name cyclones. They are given the name typhoons in Southeast Asia.
How do Hurricanes form?
Hurricanes form over the warm ocean water of the tropics when the warm moist air over water starts to rise. The moist warm water is replaced by cooler water which in return starts to rise. This cycle results in huge storm clouds that start to rotate. These huge storm clouds, along with wind speeds, form a hurricane.
What are the Parts of Hurricanes?
There are five parts of hurricanes:
- Eye: it is at the center of the hurricane. It is an area of descending air. There are not usually any clouds in the eye and the wind there is calm. However, the most dangerous part of the storm is at the edge of the eye which is called the eyewall.
- Eyewall: it is around the outside of the eye. It is a wall formed of very heavy clouds. This is considered the most fatal part of the hurricane and where the highest speed winds are. The winds at the eyewall can get to speeds of 155 miles per hour.
- Rainbands: hurricanes contain large spiral bands of rain called rainbands. These bands can throw down huge amounts of rainfall causing flooding when the hurricane crashes land.
- Diameter: hurricanes can turn into huge storms. The diameter of the hurricane is calculated from one side to the other. Hurricanes can measure a diameter of over 600 miles.
- Height: the storm clouds that give hurricanes power can become very tall. A powerful hurricane can go up to nine miles into the atmosphere.
What are the Stages of Hurricane?
A hurricane has 6 stages as follows:
- Disturbance Formation
- Tropical Disturbance
- Tropical Depression
- Tropical Storm
The first stage of a hurricane starts with disturbance formation. Hurricanes are made of a mixture of many factors. A hurricane starts to form due to the evaporation that happens over tropical ocean waters.
Once it starts to evaporate, a cloud of warm air begins to shape, heating the air around it and forming even more densely packed clouds as air rushes in. As the air still heats up, a large mass of warm rain clouds is formed over the ocean.
In the second stage, the tropical disturbance is made of loosely packed rain clouds creating thunderstorms. The wind circulation is light, with minimal chances to cause any amount of damage. If this storm system can maintain its structure for more than 24 hours, it is considered a tropical disturbance.
A tropical disturbance will change to a tropical depression when it has wind speeds of anywhere between 23 mph to 38 mph. Once winds turn to be more organized, they start to circulate in the center of the storm.
A tropical depression will start to form into a more significant storm. However, at this stage, it doesn’t have the power to move on to the next step and it still lacks the true form.
Before the hurricane formation, a tropical storm is formed first as the tropical depression grows increasingly stronger. The wind speeds at this stage jump from 39 mph to around 73 mph.
Tropical storms are similar to smaller forms of hurricanes and aren’t as threatening. But a tropical cyclone is nothing to pass over, though. Tropical storms can still result in heavy rains that can cause severe flooding wherever they make landfall.
If the tropical storm is forming at wind speeds that go up to at least 74 mph, it is clearly a hurricane. It takes the real final form of a hurricane as its eye forms completely.
Hurricanes are categorized according to their wind speeds. They include:
- Category 1 Hurricane: Wind speed ranges from 74 miles per hour to 95 miles per hour.
- Category 2 Hurricane: Wind speed ranges from 96 miles per hour to 110 miles per hour.
- Category 3 Hurricane: Wind speed ranges from 111 miles per hour to 129 miles per hour.
- Category 4 Hurricane: Wind speed ranges from 130 miles per hour to 156 miles per hour.
- Category 5 Hurricane: Wind speed ranges from over 157 miles per hour.
As hurricanes continue to flow over warm tropical waters, they’ll continue to gather power and speed. Once they make landfall, they stop gathering power because they no longer have warm water to depend on to power themselves.
So during landfall, they turn to be less and less organized as wind speeds fall dramatically. Finally, the hurricane will start to be divided into thunderstorms, before breaking down completely. While the hurricane floats over land, its high-speed winds and heavy rains result in massive damage, probably levelling entire towns in the process.
What are the types of Cyclones?
A cyclone represents a weather system marked by circling winds around a low-pressure center. The wind direction around the center is counterclockwise in the Northern Hemisphere, while in the Southern Hemisphere the wind direction is clockwise.
Coming in a large variety of sizes and settings, cyclones cause some of the most dramatic and complete violent weather on the planet, including the tropical cyclones known as hurricanes and typhoons. The science behind cyclones helps you realize where and why this weather phenomenon exists.
A tropical cyclone is defined by The National Weather Service as “a rotating system of clouds and thunderstorms that originated over tropical or sub-tropical areas.”
The significant tropical-cyclone basins include the North Atlantic (including the Caribbean), North Indian Ocean, Southwest Indian Ocean, Eastern Pacific, Western Pacific, Southern Pacific and Australian region.
Exactly tropical cyclones grow within 5 and 30 degrees of latitude, as they need ocean waters of around 80 degrees Fahrenheit to form. Winds funnel into a low-pressure disturbance, evaporating warm surface waters and unleashing energy as rising air condenses into clouds.
Hurricanes, Cyclone, Typhoons and Tornadoes
The terminology connected to tropical cyclones can be confusing because people call these violent storms by different names in different parts of the world. In the North Atlantic, the Caribbean, and the northeastern Pacific too, people call them “hurricanes”.
In the Northwest Pacific, “a typhoon” is the most active tropical-cyclone basin in the world. While in the Indian Ocean and South Pacific, people call them “tropical cyclones” or “cyclones”. Tornadoes are called “cyclones,” yet they’re completely different storms.
Mesocyclones: Tornado Factories
Supercell thunderstorms are the name given to especially strong thunderstorms that display circling updrafts called mesocyclones. Rotating “wall clouds” may fall from mesocyclones and ultimately form a funnel cloud.
If a funnel cloud touches the ground, it turns into a tornado. The United States underwent approximately 1,700 mesocyclones in a year, with about 50 percent of these turning into tornadoes.
Midlatitude or Extratropical Cyclones
Hurricanes and typhoons may be popular to laypeople, but the cyclonic storms that grow along frontal boundaries in the middle latitudes are just as significant.
These cyclones, which grow where sharp temperature gradients exist between adjoining air masses, can be much larger than hurricanes, though their winds are generally weaker. A remarkable example of a midlatitude cyclone is the “nor’easter” that often affects the U.S. East Coast, particularly in winter.
Polar Lows, aka “Arctic Hurricanes”
Hurricanes frequently form over Arctic and Antarctic seas, sparked by freezing air moving over somewhat warmer ocean waters. In the Northern Hemisphere, scientists sometimes call polar lows “Arctic hurricanes,” because both their power source as well as their circling cloud bands are somewhat similar to a tropical cyclone. Polar lows often form quickly, sometimes in less than 24 hours, and it is not easy to forecast.
How Do Scientists Forecast Hurricanes?
Scientists can guess when hurricanes may happen depending on the complicated tools available. However, it is not guaranteed that the timing is accurate. Hurricane predictions can be divided into two categories: seasonal probabilities and the track of a current hurricane.
Scientists can’t give exact dates and times for hurricanes. However, they calculate the wind speed and the past occurrences of hurricanes to forecast possible hurricanes to form.
Scientists can track the path of a hurricane once it is formed using a lot of models. They can also forecast the intensity of the hurricane which is very important to give people chances to prepare for the hurricane. However, forecasting isn’t accurate enough.

Both hurricanes and Tornadoes are natural phenomena. They are fatal and cause a lot of damage. They cause strong sustained winds. Let’s have a look at some of the differences between hurricanes and tornadoes:
|It occurs in the warm water tropics||It occurs on land|
|It can be up to hundreds of miles wide||It is usually less than a quarter-mile wide|
|The highest sustained winds can reach 100 mph||The wind can reach 300 mph|
|Around 10 tropical storms can occur in a year in the Atlantic Ocean||From 800 to 1000 tornadoes in a year in the U.S.A|
|It can be predicted several days ahead||It can be predicted 15:30 minutes ahead|
|The greatest damages are caused by floods||The greatest damages are caused by winds|
|It is huge but slow||It is not predictable but fast|
|It occurs in warm areas||It occurs anywhere|
|Diameter ranges from 60 to 1300 miles||Diameter is about 100 meters|

Some Hurricane Survival Stories
- Story of Carol Park: The story goes back to September of 1961 in the Gulf of Mexico when Carol was only 10. She witnessed Hurricane Carla which is a category 5 hurricane. She was playing outdoors and her family didn’t take any precautions. There were heavy rains and violent winds. She still remembers the mixed feeling of fear and excitement.
- Story of RJ Cywinski: He was 11 years old. His family had to evacuate their home. They left for a shelter with their pets. They found a lot of people there as well. He felt terrified while they were driving to the shelter as if the storm was following them.
- Story of Bill: Bill witnessed hurricane Sandy in November 2012 in New York. He and his family were under the impression that they got ready for the hurricane. They prepared the emergency bag and all the needed supplies. However, the hurricane was much stronger than expected. Trees bent down and the power went down as well. Roads were blocked by the falling trees so there was nowhere to go. They had to stay at home away from the windows until the hurricane passed.
- Story of Christina: She witnessed 3 major hurricanes in the area of Virginia in 2003, 2011, and 2018. During the first hurricane, power went off for 13 days. They didn’t have access to gas or ice. During the 2nd hurricane again power went off for 7 days. The wind was terrifying. The third experience, power went off for 5 days. Some roads were blocked.
