Document Summary
Water can be found in three states in the environment: solid ice, liquid water, water vapour. Knowing how much water vapour there is in the atmosphere can help tell how much latent heat is in the atmosphere. Humidity - the amount of water vapour in the air. It can be expressed through a few ways: absolute humidity. Is the mass of water vapour as a ratio to the volume of air. Not commonly used due to frequent change in volume. The change in this value doesn"t necessarily mean that the amount of water vapor changed, just the volume. The mass of water vapour (grams) / parcel size (m3: specific humidity. Is the mass of water vapour as a ratio to the mass of the air both measured in kg. Does not change as air contracts or expands. In polar regions, specific heat values fall off rapidly as.
