Specific Humidity

  • specific humidity is defined as

specific humidity = mass of water vapor/total mass of air

  • example:

  • in a given parcel, the mass of water vapor is 1 gm

  • the total mass of the parcel (N2, O2, AR, H2O, other trace gasses) is 1 kg

  • then the specific humidity is: ANSWER

  • Q: what will the latitudinal distribution of specific humidity look like?
