Tropical Cyclone Wind Radius
A precise tool.
What is the Tropical Cyclone Wind Radius & How does it work?
Tropical cyclones are large, swirling storms that form over warm ocean waters. The wind radius of a tropical cyclone is the distance from its center to the location where the wind speed drops below a specified threshold, typically 34 knots (63 km/h) for Category 1 hurricanes.
The wind radius can vary significantly depending on the category and intensity of the tropical cyclone. Generally, higher-category storms have larger wind radii, meaning their destructive winds extend over a wider area.
R = frac{V}{beta V_{max}}
R = Wind radius, V = Wind speed threshold, beta = Decay constant, V_{max} = Maximum sustained wind speed

Frequently Asked Questions
What is the wind radius for a Category 1 hurricane?
The wind radius for a Category 1 hurricane typically extends to about 34 knots (63 km/h) from the center.
How does wind radius change with tropical cyclone intensity?
Higher-category storms generally have larger wind radii, meaning their destructive winds extend over a wider area.
What factors influence the wind radius of a tropical cyclone?
Wind radius can vary based on the storm’s category, intensity, and environmental conditions such as sea surface temperature and atmospheric stability.
Can you explain how to use this calculator for tropical cyclones?
Input the category and intensity of the tropical cyclone to determine its wind radius. The calculator will provide the distance from the center where wind speeds drop below a specified threshold.
Why is it important to know the wind radius of a tropical cyclone?
Knowing the wind radius helps in assessing the potential impact area and planning evacuation routes, as well as understanding the extent of potential damage from high winds.
