“S-290 Unit 5: Temperature and Relative Humidity Relationships” module focuses on methods of describing humidity in the atmosphere and how temperature changes can affect relative humidity. Topics from this module will be further related to effects on potential fire behavior in other modules of the Intermediate Wildland Fire Behavior Course.
1. Describe the relationship between dry bulb temperature, wet bulb temperature, dewpoint temperature, and relative humidity.
2. Describe typical day and night (diurnal) variations in air temperature and relative humidity.
3. Determine relative humidity, dewpoint, and wet bulb temperatures using a psychrometric table.
4. Describe the effects of topography, vegetation, clouds, and wind on air temperature and relative humidity.
5. Describe the temperature and relative humidity characteristics of continental and maritime air masses.
