Wind-shift lines refer to visible markings left on the surface of water that indicate a change in wind direction or intensity. They are also known as wind lines, wind ripples, or wind waves. Sailors and windsurfers rely on wind-shift lines to navigate and anticipate changes in the wind direction. These lines are formed by the movement of wind-driven water currents, and can appear as ripples or waves on the water's surface. Other synonyms for wind-shift lines include wavelets, cat's paws, and zephyrs. Understanding the various synonyms for wind-shift lines can help sailors and water sports enthusiasts better predict and manage wind conditions while on the water.
