Wind direction refers to the direction from which the wind is blowing. It is typically measured in degrees, with 0° representing north, 90° east, 180° south, and 270° west. For example, a wind coming from the north is called a north wind, while a wind blowing from the east is known as an east wind. Wind direction is important for various activities, including weather forecasting, aviation, and sailing. Understanding wind patterns helps meteorologists predict weather changes and assists sailors in navigating effectively. Wind direction can also influence temperature and precipitation in a given area.
