what are mountain breeze caused by
In the evening, the mountain slopes cool the surrounding air more quickly than the air found lower in the atmosphere. This creates a high pressure as air becomes more densely packed. The resulting high pressure causes winds to blow down the mountain towards the valley floor. This type of wind pattern is known as a mountain breeze. Thus, in the daytime we typically see valley breezes as winds blow from the valley up towards the mountains. In the night we often see mountain breezes as winds travel from the mountains down towards the valleys.
