Wind behavior refers to the movement of air caused by differences in atmospheric pressure. When warm air rises, cooler air moves in to replace it, creating wind. The speed and direction of wind can vary based on factors like terrain, temperature, and the Earth's rotation. Wind can be classified into different types, such as breezes, gales, and hurricanes, depending on their speed and intensity. Local features like mountains and valleys can also influence wind patterns, causing it to change direction or speed as it flows over and around these obstacles.
