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.
Local winds, on the other hand, are winds such as sea and land breezes. These breezes are produced from the cooling and heating of the air above the coastal shores and the sea. During the day, the warm air near the land rises and draws cooler air inward from the sea.
