As it sinks in the valley, the air is compressed because of the growing air tension and heated adiabatically (i.e. without having warmth Trade). Because of this, the temperature of your wind rises by about just one degree Celsius for each hundred metres of altitude.
When air is pressured upwards above elevated terrain, it expands and cools a result of the lower in stress with top. Considering the fact that colder air can keep considerably less drinking water vapour, dampness condenses to kind clouds and precipitates as rain or snow over the mountain's upwind slopes. The adjust of state from vapour to liquid drinking water is accompanied by heating, and the next elimination of moisture as precipitation renders this heat attain irreversible, resulting in The nice and cozy, dry foehn ailments while in the mountain's lee.
