The air in the valley quickly warms up during the day and rises upward. Mountain air cools more quickly at night and descends into the valley.
The true explanation for mountain-valley breezes is that during the day, the valley air quickly warms and flows upslope, while at night, the mountain air quickly cools and descends into the valley.
When the valley bottom warms up during the day, it should be observed that the warm air will then rise to the surrounding mountain slopes, creating a valley breeze. The cooler, denser air will then glide down the slopes during the night and settle in the valley, creating the mountain breeze.
