Water content of air
Percent of water air could hold at a given temperature
Fluctuates hourly as temperature changes
Saturation point = condensation
Condensation = clouds
Normally, a mass of warm air rises above a mass of cooler air when the two masses meet. As the warmer mass cools, there is condensation and possibly precipitation.
