Under the waves, too."Hurricanes get boost from ocean spray" (SN: 8/6/05, p. 94) reports on research indicating that winds above the ocean surface can increase due to an apparent damping damping In physics, the restraint of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipating energy. Unless a child keeps pumping a swing, the back-and-forth motion decreases; damping by the air's friction opposes the of turbulence turbulence, state of violent or agitated behavior in a fluid. Turbulent behavior is characteristic of systems of large numbers of particles, and its unpredictability and randomness has long thwarted attempts to fully understand it, even with such powerful tools as by particles of ocean spray. I would like to point out that a similar phenomenon has been identified in rivers. In situations where the transport of fine sediment particles (sands, clays) coming from the riverbed is large, the apparent bed friction is decreased compared with similar clear-water conditions. That decrease has been attributed to dampening of the turbulence by the suspended sediment particles. Perhaps a joint research effort would be mutually beneficial Adj. 1. mutually beneficial - mutually dependent interdependent, mutualist dependent - relying on or requiring a person or thing for support, supply, or what is needed; "dependent children"; "dependent on moisture" .
