Hurricanes

✨ The Giant Sea Top

A hurricane is a powerful tropical cyclone that forms over warm ocean waters in the Atlantic Ocean and the northeastern Pacific Ocean. The same type of storm is called a typhoon in the northwestern Pacific and a tropical cyclone in the Indian Ocean and the South Pacific. Hurricanes develop when seawater is at least about 26.5°C, providing heat and moisture that fuel the storm.

As warm, humid air rises, it creates an area of low pressure that draws in more air. Earth's rotation causes the system to spin, forming a spiral of thunderstorms around a relatively calm center known as the eye. A storm is classified as a hurricane when its maximum sustained winds reach at least 119 km/h.

As hurricanes move across the ocean or make landfall, they can produce destructive winds, torrential rain, storm surges and flooding. Storm surges occur when strong winds and low atmospheric pressure push seawater toward the coast, sometimes causing severe coastal flooding. Although hurricanes usually weaken over land because they lose their supply of warm, moist air, they can still bring heavy rainfall far inland.

Meteorologists monitor these storms using satellites, weather radar, aircraft and computer models to predict their path and intensity. Early warnings and evacuation plans help reduce the risks to people, while ongoing research improves our understanding of how hurricanes form and how climate conditions influence their behavior.

💡 Did you know?

Did you know the center of a hurricane is called the 'eye'? It's the strangest place in the world: while the winds are totally unleashed all around, inside the eye, there is almost no wind and you can even see the blue sky! But beware, this calm is short-lived because as soon as the eye has passed, the wind starts blowing very hard again in the other direction.

Scientists use special planes, called 'Hurricane Hunters', to fly directly inside these monsters! They drop sensors to measure wind strength and pressure. It's a very brave but essential job to warn residents and save lives before the storm reaches cities.

Depending on where they are in the world, these storms have different names. In the Atlantic Ocean, they are called hurricanes. In the Indian Ocean, they are cyclones, and in the Pacific Ocean, they are called typhoons. It's exactly the same phenomenon, but each region has given it its own nickname!
