What is a hurricane for elementary students?
A hurricane is a large rotating storm with high speed winds that forms over warm waters in tropical areas. Hurricanes have sustained winds of at least 74 miles per hour and an area of low air pressure in the center called the eye.
What are some interesting facts about hurricanes for kids?
A hurricane is a huge storm! It can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph. Each hurricane usually lasts for over a week, moving 10-20 miles per hour over the open ocean. Hurricanes gather heat and energy through contact with warm ocean waters.
What are 5 interesting facts about hurricanes?
A typical hurricane can dump 6 inches to a foot of rain across a region. The most violent winds and heaviest rains take place in the eye wall, the ring of clouds and thunderstorms closely surrounding the eye. Every second, a large hurricane releases the energy of 10 atomic bombs. Hurricanes can also produce tornadoes.
How do scientists study hurricanes for kids?
They include satellite imagery of the surface temperature of the ocean, radar to locate precipitation and estimate its motion and type (rain, snow, etc.), computer models that rely on current and past weather patterns to make predictions, floats that collect measurements of ocean water temperature, and a fleet of …
What is the middle of a hurricane called?
The Eye the center of the storm. The most recognizable feature found within a hurricane is the eye. They are found at the center and are between 20-50km in diameter. The eye is the focus of the hurricane, the point about which the rest of the storm rotates and where the lowest surface pressures are found in the storm.
What is hurricane short answer?
What is a hurricane? Hurricanes are enormous storms which come with rotating wind speed of 74 miles per hour. The rotating wind swirls across the warm water of the tropics and comes with terrifying force. This force blast ashore which causes destruction and even death.
How long can a hurricane last?
A typical hurricane lasts anywhere from 12 to 24 hours. But a hurricane can sustain itself for as long as a month, as Hurricane John did in 1994.
Where do all hurricanes start?
“In the Atlantic region, hurricanes form anywhere from the tropical central Atlantic to the Gulf of Mexico. Those that form in the central Atlantic and Caribbean region usually start off moving westward; when they recurve, they may strike the North American mainland.
What triggers a hurricane?
A pre-existing weather disturbance: A hurricane often starts out as a tropical wave. Warm water: Water at least 26.5 degrees Celsius over a depth of 50 meters powers the storm. Thunderstorm activity: Thunderstorms turn ocean heat into hurricane fuel.
What causes a hurricane for children?
They mainly form over the ocean. Hurricanes start when moist warm air above the water rises and is replaced by cooler air. This cool air then warms up and rises and this causes a cycle which then creates a storm. In the unlucky event that a hurricane hits the land, it causes the hurricane to weaken and slow down.

When does a tropical storm become a hurricane?
When the winds in the rotating storm reach 39 mph, the storm is called a “tropical storm.” And when the wind speeds reach 74 mph, the storm is officially a “tropical cyclone,” or hurricane. Tropical cyclones usually weaken when they hit land, because they are no longer being “fed” by the energy from the warm ocean waters.
Are there any Hurricanes in the Atlantic Ocean?
People call these storms by other names, such as typhoons or cyclones, depending on where they occur. The scientific term for all these storms is tropical cyclone. Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called “hurricanes.”
Where does the wind have to be at for a hurricane to form?
Also, the wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface. Winds flow outward above the storm allowing the air below to rise. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator.
