Document Summary

A lot of water vapour is in equatorial regions. Warm areas can hold much more water vapour than cold air. Because of the cold temperatures, high latitude regions tend to not hold much water vapour. Solid to liquid to gaseous consumption of latent heat or the release of latent heat. Transfer of water vapour through clouds moving from one place to another. Mass of water vapour per volume of air. Not commonly used due to the volume changes that the absolute humidity implies. Sh=mass of water vapour (g)/ mass of total air (kg) Two different volumes contain the same mass, therefore have the same specific humidity. The warmer the temperature the higher the water vapour content. Specific humidity values fall off rapidly as temperature in these regions decreases. More insolate is available at lower latitudes to evaporate water from oceans or moist land surfaces. Therefore, specific humidity and temperature values are high at low latitudes.
