Have your children asked you what is a hurricane and how is it formed? We are going to help you understand it so that your explanation to the children is simpler and clearer. We even propose a game to explain it to them! Hurricanes or tropical cyclones They are big and strong storms that form in the sea and that can cause winds with a speed of over 100 and even 200 km per hour. They are formed on warm water (above 27 / 28ºC) of the Atlantic Ocean and the eastern Pacific Ocean.
They start out as a storm with winds that rotate counterclockwise and grow fueled by the heat of the ocean and the water that evaporates from the surface. The amount of evaporation results in a low pressure center with large vertical projection, and there is a continuous entry of cold air in the upper layers. When the intensity of a tropical cyclone exceeds the Tropical Storm classification, it becomes a hurricane.
Children are always very curious to know how the hurricanes, why there are tsunamis, how the wind changes and also what makes the lunar cycles change. Other issues that also interest children are the changes of season, the fall of the leaves of the trees, or even the color of the sky or the sea water.
To know how to explain the natural processes children, it is necessary to know how they are formed. Thus, in the face of the constant 'Mom, why ...?' We will have an easy and fast answer so that they have more and more knowledge.
The first thing a child wants to know is what exactly a hurricane. To be able to explain it to you, the first thing you should know is the concept of wind, which is the mass or current of air that changes in pressure when it occurs in the atmosphere.
1. What is the wind?
For a child to understand perfectly what the wind is, we can use a small folded paper or a Ludo chip, for example, that we will put upright on the table, and when blowing it or using an object such as a hair dryer in motion , will fall. In this way, the child will understand that the wind It is that air that moves depending on what happens in the atmosphere - it is subject to changes in temperature or precipitation - and that manages to impact the environment, that is why it moves or the token falls.
2. What is a hurricane?
Later, it will be time to find out what a hurricane is, that much larger version of the conventional wind that we know and that occurs at sea, unlike a tornado, and that can also last for several days.
The version in play so that they understand that great whirlpool that forms the hurricane itself, can be carried out with a dryer that has multiple speeds. Thus, as we increase the power, the child will be able to see with their own eyes how the wind (which starts from a blow, or from the lowest power of the dryer), can turn according to its speed and power into a tropical depression, which will give it happened to a tropical storm and later to a hurricane.
3. Where do hurricanes form?
Hurricanes potentially arise in the tropical oceansWith the help of a map, a globe of the world or images that we will find on the Internet, we can teach our children in which areas of the world this type of phenomenon usually occurs. What the children will ask how fast that wind blows, capable of even impacting on houses, trees or any element in front of it, and being capable of becoming an atmospheric phenomenon. To do this, we must have clear three phases, which we talk about in the following questions.
4. What is a tropical depression?
Before the hurricane appears, the winds blow with a force of about 62 kilometers per hour, this means that it is a cyclone with a medium force at sea level. With the help of the lowest power of a dryer, the child will be able to see that the pieces of paper or the pieces of a game that we place, are moving although they do not fall completely.
5. What is a tropical storm?
This is the second pass of the wind before becoming a hurricane, which can be found between 63 and 117 kilometers per hour, so the force at sea level is much higher than the tropical depression.
As this speed per minute increases, we would be closer to producing a hurricane. If we can put the dryer to higher power, this homemade tropical storm will cause the papers to move faster and faster and fall.
6. How does a hurricane form?
It is a full-fledged tropical cyclone, so its speed per minute far exceeds the 118 kilometers per hour, but they can reach 250. The dryer set will reach its maximum power and will throw away all the papers. It is necessary to know that the hurricane season extends between summer and fall, and that they are difficult to control. The eye of the hurricane extends from sea level to the highest part of its whirlpool, surrounded by thick clouds that will give way to the rain. Normally the air will be very humid and that will give way to their formation.
When a hurricane makes landfall, it loses contact with the warm water it needs for its development and is weakened, although it can regenerate if it goes out to sea again.
The hurricane, as well as the typhoon and a tropical cyclone occur in the same way. They grow by categories but there is something different between them. Why do they have different names? They have different names depending on where they are produced. The scientific term for all these storms is tropical cyclone. Only tropical cyclones that form over the Atlantic Ocean and the eastern Pacific Ocean are called hurricanes.

It occurs in the north of the Atlantic Ocean; in the northeast Pacific Ocean, east of the international timeline; and in the southern Pacific Ocean, east of 160 ° E longitude.
A typhoon is a mature tropical cyclone that develops between longitudes 180 ° and 100 ° E in the northeastern Pacific, a typhoon occurs in the northwestern Pacific Ocean. It occurs in the northwestern Pacific Ocean, west of the international time line.
- Strong tropical cyclone or cyclone from category 3 onwards
It occurs in the southwestern Pacific Ocean, west of 160 ° E longitude; and in the southeastern Indian Ocean, east of longitude 90 ° E.
- Strong cyclonic storm
It occurs in the northern Indian Ocean.
- Tropical cyclone
It occurs in the southwestern Indian Ocean.
As every year, the National Hurricane Center of the United States prepares a list of proper names, female and male, for the following hurricane season that take place in the Atlantic Ocean. The list contains a name for each letter of the alphabet (the letters Q, U, X, Y, Z are not included because few names begin with those letters). These lists are repeated every six years, and the names of the hurricanes that have been devastating are changed to another with the same initial and gender.
