Data Source and Methodology

All calculations are based on the formulas and data provided by the NOAA's National Weather Service. For more information, visit NOAA's official page.

The Formula Explained

The Fujita scale uses wind speed estimates to categorize tornadoes into levels from EF0 to EF5. The formula is based on observed damage and wind speed data.

Glossary of Terms

  • Wind Speed: The estimated speed of the wind in miles per hour.
  • Intensity: The level of the tornado on the Fujita scale.

How It Works: A Step-by-Step Example

To determine the intensity, input the estimated wind speed. The calculator will categorize the tornado intensity based on Fujita scale thresholds.

Frequently Asked Questions (FAQ)

What is the Fujita Scale?

The Fujita scale rates tornadoes based on wind speed and damage. It ranges from EF0 (weakest) to EF5 (strongest).

How accurate is the Fujita Scale?

The scale provides estimates based on damage and is widely used in meteorology.

Can this calculator be used for real-time tornado warnings?

This tool is for educational purposes and should not be used for real-time warnings.
