There are usually four to six hurricanes in a year that will cause some destruction on land. Hurricanes are tropical storms. They take place between the equator and Tropic of Capricorn to the south.
Hurricanes form at sea and cause dangerous, stormy seas. Some hurricanes reach the land and can destroy buildings and trees. The hurricane season lasts from the beginning of June until the end of November.
A hurricane can blow high waves onto the land and cause flooding.
How is hurricane caused?
They are forms in the areas of less pressure.
- They are formed tropical area or zone of less pressure on either side of the equator.
- The ocean is warm and heats the air above it, inside the low pressure.
- The warm air rises until it cools and forms thundery clouds.
- As the air rises, more air moves in to replace it.
- Due to the formation of more clouds, the more warm air is pushed upwards, the clouds join together and begin to spin.
- This is called the begging of the hurricane.
The meteorologists give names to all the tropical storms, hurricanes, typhoons and cyclones:
The first storm of the year begins with the letter ‘A’.
The names are male and female in order. For example in Atlantic tropical storms were:
Stages of the hurricane:
- Tropical wave: Tropical wave takes few days for a hurricane to develop due to the temperature of the sea and wind conditions can mean it takes longer.
This first stage of hurricane development is the formation of a tropical wave, which features winds that blow from east to west.
Tropical disturbance and tropical depression:
This is the second stage of a hurricane development is formed of a tropical disturbance, shown as thunderstorms. A tropical disturbance typically begins in a tropical or subtropical area, and it will last for at least 24 hours. It is characterized by rainfall and wind. It makes a transition into the third stage, which is a tropical depression, a low-pressure system with continuous winds and thunderstorms.
It is the fourth stage of hurricane development, a tropical storm that forms with surface wind speeds. At this stage, the storm has a closed circulation. Which mean winds are blowing in a clockwise direction with a low-pressure center. The manifestation of a tropical storm is often a strong indication that a hurricane might strike a certain area, and at this point, the national hurricane center will usually assign a name of the storm.
- A hurricane is an intense tropical storm with powerful winds and heavy rain.
- Other names for a hurricane include cyclone, typhoon, and tropical storm.
- Hurricanes usually form in tropical areas of the world.
- Hurricanes develop over warm water and use it as an energy source.
- Hurricanes lose strength as they move over land.
- Coastal regions are most in danger from hurricanes.
- As well as violent winds and heavy rain, hurricanes can also create tornadoes, high waves, and widespread flooding.
- Hurricanes are regions of low atmospheric pressure also known as a depression.
- The wind flow of hurricanes in the southern hemisphere is clockwise while the wind flow of hurricanes in the northern hemisphere is counterclockwise.
- The winds around the eye of a hurricane are usually the strongest.
