Tropical Cyclones: Understanding the Anatomy of a Storm

What is a Tropical Cyclone?

A tropical cyclone is a rapidly rotating storm system that forms over warm tropical oceans.

These storms are characterized by:

• A low-pressure center
• A closed low-level atmospheric circulation
• Strong winds
• A spiral arrangement of clouds

Types of Tropical Cyclones

Tropical cyclones are classified into five categories based on their wind speed:

• Tropical depression: Winds below 38 mph
• Tropical storm: Winds between 39 and 73 mph
• Category 1 hurricane: Winds between 74 and 95 mph
• Category 2 hurricane: Winds between 96 and 110 mph
• Category 3 hurricane: Winds between 111 and 129 mph
• Category 4 hurricane: Winds between 130 and 156 mph
• Category 5 hurricane: Winds of 157 mph or higher

Characteristics of Tropical Cyclones

Tropical cyclones are warm-core systems, meaning they have warmer air at their center than at their edges.

They also have a well-defined eye, which is a central area of calm weather with low pressure.

The outer bands of a tropical cyclone typically contain the heaviest rainfall and strongest winds.

Impacts of Tropical Cyclones

Tropical cyclones can cause widespread damage and loss of life.

Their impacts include:

• High winds
• Heavy rainfall
• Coastal flooding
• Storm surge
• Tornadoes

Preparing for Tropical Cyclones

The best way to prepare for a tropical cyclone is to be aware of the risks and to have a plan in place.

Here are some tips:

• Stay informed about weather forecasts and warnings.
• Secure your home and property.
• Stock up on food, water, and other essential supplies.
• Identify evacuation routes and shelters.
• Be prepared to evacuate if necessary.

Conclusion

Tropical cyclones are powerful and potentially deadly storms.

By understanding their characteristics and impacts, we can better prepare for and mitigate their risks.
