  1. Air-sea momentum transfer in high wind conditions: laboratory experiments. Ivan Savelyev Sponsored by: Advisors: Brian Haus and Mark Donelan

  2. Background

  3. Experiment Setup Air-Sea Interactions Salt-Water Tank at RSMAS, University of Miami. Dimensions: 15x1x1 meters, Maximum wind speed U=30 m/s, Fully programmable wave-maker with wave height up to H = 10 cm.

  4. Wave-follower experimental setup.

  5. Wave-follower in motion

  6. Digital Laser Elevation Gauge (DLEG)

  7. DLEG image of the air-sea interface at

  8. Figure 2 from “On the limiting aerodynamic roughness of the ocean in very strong winds”, Donelan et al., 2004.

  9. Summary and future work 1) The new high precision wave-follower system was developed and proofed to be successful. 2) First wave-follower based static pressure measurements show that wave growth function keeps growing quadratically as wind forcing enters hurricane-like conditions. 3) Both dimensional and non-dimensional approaches are necessary to resolve form drag contribution to a total drag in high-wind conditions. 4) In the future experiments will be studied as a function of wind speed, wind forcing and wave steepness.
