Table 1: The Grain Harvesting Operations Table ... calculate if wind speed is too high to harvest
The Grain Harvesting Operations Table calculates the average wind speed (km/hr) for different temperatures (°C) and relative humidity (RH %) combinations that equate to a Grassland Fire Danger Index of 35, for example:
1. Temperature = 35°C
2. Relative humidity = 14% (round down to 10%)
3. For this combination, grain harvesting must cease when average wind speed is greater than 26km/hr.
