Hurricane Live: An In-Depth Look at the Anatomy of a Hurricane
What is a Hurricane?
A hurricane is a warm-core, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. It is characterized by a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain.
Anatomy of a Hurricane
The anatomy of a hurricane can be divided into four main parts: the eye, the eyewall, the rainbands, and the outflow.
The Eye
The eye is the calm center of the hurricane. It is typically 20-40 miles in diameter and is characterized by light winds and clear skies.
The Eyewall
The eyewall is the area of the hurricane where the strongest winds are found. It is a ring of thunderstorms that surrounds the eye and can be up to 10 miles wide.
The Rainbands
The rainbands are the areas of the hurricane where the heaviest rain falls. They are typically located outside the eyewall and can extend for hundreds of miles.
The Outflow
The outflow is the area of the hurricane where the air flows outward from the center. It is located above the rainbands and helps to maintain the hurricane's circulation.
How Hurricanes Form
Hurricanes form over warm ocean waters when the following conditions are met:
- The ocean water temperature is at least 80 degrees Fahrenheit.
- There is a low-pressure system in the area.
- There is enough moisture in the air.
- There is a force called the Coriolis effect that helps to create the hurricane's spiral shape.
Hurricane Categories
Hurricanes are classified into five categories based on their wind speed. The categories are:
- Category 1: Winds from 74 to 95 mph
- Category 2: Winds from 96 to 110 mph
- Category 3: Winds from 111 to 129 mph
- Category 4: Winds from 130 to 156 mph
- Category 5: Winds of 157 mph or higher
Hurricane Hazards
Hurricanes can cause a variety of hazards, including:
- High winds
- Heavy rain
- Flooding
- Storm surge
- Tornadoes
Hurricane Preparation
There are a number of things that you can do to prepare for a hurricane, including:
- Have a hurricane plan in place.
- Gather emergency supplies.
- Secure your home.
- Stay informed about the hurricane.
- Be prepared to evacuate if necessary.
Hurricane Safety
If you are in the path of a hurricane, it is important to take the following safety precautions:
- Stay indoors.
- Stay away from windows.
- Do not drive unless it is absolutely necessary.
- Be aware of the potential for flooding and storm surge.
- Listen to the radio or television for updates on the hurricane.
