What role does fabric play in visualizing air currents or wind patterns in nature?

Fabric serves as a powerful tool for visualizing air currents and wind patterns in nature due to its lightweight and flexible properties. When exposed to wind, fabrics like silk, chiffon, or lightweight cotton move dynamically, revealing the direction, speed, and turbulence of airflow. This phenomenon is often used in scientific experiments, artistic installations, and even outdoor activities like kite flying or sail testing. By observing how fabric ripples, flutters, or billows, researchers and enthusiasts can gain insights into fluid dynamics without complex instruments. Additionally, fabrics are employed in wind tunnels to study aerodynamic effects, making them an accessible and practical medium for understanding invisible natural forces. From weather vanes to flowing garments, fabric bridges the gap between abstract wind patterns and tangible human observation.
