To estimate effective temperature, draw a line from the appropriate point on the top scale (air temperature) to the appropriate point on the windspeed scale at the bottom. The effective temperature is the point at which the line crosses the middle scale. In the example, a wind speed of 30 km/h (bottom scale) lowers a temperature of minus 20°C (top scale) to an effective temperature of 31°C (middle scale).
