How is heat transfer by conductive currents modified by the water content of the air?
Conductive heat transfer is from contact with another object like a drop of moisture. The heat is transferred from one object to the other equalizing the temp in both. The higher the moisture content in the air the faster the heat transfer. The east-west flow and the jet stream push moist air across the continent. When this moist air contacts cold air it cannot support as much moisture and so the moisture comes down as rain. This also occurs when cold meets warm air. knowing the amount of moisture in the air and the temperature they can determine approximately when that moisture will be released. The saturation point for that particular temp.
