Web28 feb. 2024 · Photo credit: Beth Clawson, MSU. In its simplest term lake fetch is the maximum length of open water wind can travel. Waves are formed by wind. Therefore, the highest energy waves are going to form where there is a long expanse of unobstructed water and sustained high winds. In other words, the longer that wind blows over a … WebWind blowing over a calm lake surface first produces an effect that may appear as a widely varying and fluctuating ruffling of the surface. The first wave motion to develop is relatively regular, consisting of small, uniformly developed waves called capillary waves. These are quite transient, dissipating rapidly if the wind dies away or developing to the more … Web21 nov. 2013 · Antennas can be of any length related to wavelength.

Increasing any of these factors increases the energy of wind waves, and therefore their size and speed. But there is an upper limit to how large wind-generated waves can get. As wind energy increases, the waves receive more energy and they get both larger and steeper (recall from section 10.1 that wave steepness = height/wavelength).
