Vapor pressure The pressure exerted by the Valley breezes are particularly developed on south-facing slopes of a mountain in summer, where sun light is more intense in the Northern Hemisphere. Mountain and valley breezes: a local wind system of a mountain valley that blows downhill () at night and uphill (valley breeze) during the day. In the same direction as a stream or other flow, or toward the direction in which the flow is moving. Other examples of downslope flow are katabatic winds and Chinooks. Wind that flows down a mountain slope, sometimes at night (e.g., ). It is independent of other gases or vapors. In meteorology, it is considered as the part of total atmospheric pressure due to the water vapor content.

VAPOR PRESSURE The pressure exerted by the molecules of a given vapor. Morning Glory - An elongated cloud band, visually similar to a roll cloud, usually appearing in the morning hours, when the atmosphere is relatively stable. System of winds that blow downhill during the night. As the slopes become colder than the surrounding atmosphere, the lower levels of air cool and drain to the lowest point of the terrain. Mountain Breeze - A katabatic wind, it is formed at night by the radiational cooling along mountainsides. Mountain-wave clouds Stationary clouds situated downwind of a prominent mountain range and formed as a con sequence of the disturbance of the wind by the mountain range. Mountain breeze A shallow, gusty downslope flow of cool air that develops at night in some mountain valleys. For the Rhode Island newspaper The Valley Breeze, see Breeze Publications.
