Calculation Formula

Wind Speed (m/s) = sqrt( (1013 - P) * 9.81 / (air density) )

Where:
P = Barometric Pressure (hPa)
Air density is approximated as 1.225 kg/m³ at sea level and 15°C

How to Use the Cyclone Calculator

  1. Enter the barometric pressure in hPa (hectopascals). This is the atmospheric pressure at the location of the cyclone.
  2. Enter the atmospheric temperature in °C (Celsius). This is the temperature of the air at the location of the cyclone.
  3. Click the "Calculate" button to estimate the wind speed of the cyclone.
  4. The estimated wind speed will be displayed in meters per second (m/s).

Working Principle

The Cyclone Calculator uses the gradient wind equation to estimate the wind speed of a cyclone. The gradient wind equation is based on the difference between the ambient pressure and the pressure at the cyclone's center, as well as the Coriolis effect and the centrifugal force.

The formula used is:

Wind Speed (m/s) = sqrt( (1013 - P) * 9.81 / (air density) )

Where:

  • P = Barometric Pressure (hPa)
  • Air density is approximated as 1.225 kg/m³ at sea level and 15°C
