Vapor pressure The pressure exerted by the water vapor molecules in a given volume of air.
Valley breeze A shallow, upslope flow of air that develops during daylight hours within mountain valleys.
Vapor pressure The portion of the total air pressure exerted by the water vapor component of air.

Valley Breeze: An upward flow of air which developes during the day in the mountains. Vapor Pressure: The pressure exerted by the water vapor in the atmosphere. Vapor Pressure:The amount of moisture the atmosphere is holding at a given temperature.
VALLEY BREEZE An anabatic wind, it is formed during the day by the heating of the valley floor. As the ground becomes warmer than the surrounding atmosphere, the lower levels of air heat and rise, flowing up the mountainsides.
Mountain and valley breezes(1)
A local wind system of a mountain valley that blows downhill (mountain breeze) at night and uphill (valley breeze) during the day.

Mountain and Valley Breezes System of winds that blow downhill during the night (mountain breeze) and uphill during the day (valley breeze).

Mountain breezes and valley breezes are due to a combination of differential heating and geometry.
A wind that is created by air flowing uphill. Valley breezes, produced by local daytime heating, are an example of these winds. The opposite of a katabatic wind.
ANEMOMETER
An instrument that measures the speed or force of the wind.
Similar daily changes in temperature occur over irregular terrain and cause mountain and valley breezes. Other winds induced by local phenomena include whirlwinds and winds associated with thunderstorms.

atmosphere, the lower levels of air cool and drain to the lowest point of the terrain. It may reach several hundred feet in depth, and extreme cases, attain speeds of 50 knots or greater. It blows in the opposite direction of a valley breeze.
