A "🌬️🧦" is a visual representation of wind direction and intensity. It resembles a sock, typically made of lightweight fabric, that is attached to a pole or mast. The windsock's purpose is to provide a clear indication of wind conditions, particularly at airports, helipads, and other locations where accurate wind information is essential for safe operations. As the wind blows, the sock fills with air and aligns itself with the prevailing wind direction, allowing observers to determine wind speed and its changes over time.
