A mountain breeze and a valley breeze are two related, localized winds that occur one after the other on a daily cycle. They are not the same as katabatic winds, which are larger and stronger.
These winds are opposite from each other. While valley breezes occur when the warm air rises up the sides, warm air in a mountain breeze will rise up the middle.
Mountain and valley breezes form through a process similar to sea and land breeze. During the day, the sun heats up mountain air rapidly while convection valley remains relatively cooler. causes it to rise, causing a valley breeze. At night, the process is reversed. During the night the slopes get cooled and the dense air descends into the valley as the mountain wind. These breezes occur mostly during calm and clear weather.Mountain and valley breezes are other examples of local winds caused by an area’s geography. Campers in mountainous areas may feel a warm afternoon quickly change into a cold night soon after the sun sets. During the day, the sun warms the air along the mountain slopes. This warm air rises up the mountain slopes, creating a valley breeze. At nightfall, the air along the mountain slopes cools. This cool air moves down the slopes into the valley, producing a mountain breeze.
