Is the relative humidity of saturated air necessarily 100 percent?
1.) Weather (4-24-17) Water and Weather • What is Humidity • Ameasure of the amount of moisture in air. • Which can hold more water - warm or cold air • Warm air holds more water. • When it gets warmer, it feels more humid. • Relative Humidity • The amount of water vapor present in air expressed as a percentage of the amount needed for saturation at the same temperature. • Humidity makes it feel like it’s warmer out than it actually is. • Dew Point Temperature • Tends to be a better metric for when weather will be very severe. Gives you good idea of the energy in the atmosphere. • The atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form.
