This attracts the air from the valley, creating a breeze that blows from the valley floor up towards the top of the mountain. Often birds known as raptors, such as eagles, hawks, condors and vultures, float on these breezes to preserve their energy. This wind pattern is known as a valley breeze.
The sea breeze stops blowing and many times reverses itself and becomes a land breeze as the night wears on. The land cools rapidly at night and the air begins to descend. If the normal gradient wind between the high and low pressure areas on the weather map is blowing from the land, it will resume at night.
