Investigations of air–water momentum and heat transport at extremely high wind speeds are crucial. Three different types of wind wave tanks are used to develop a method for investigating transport in laboratories using a tank with removable solid or net bottom walls to suppress wind wave development. The wind profile and water–level fluctuations are measured by Pitot tubes, differential manometers, and wave gauges. The air-side friction velocities are estimated using the profile method. The friction velocities are damped in the cases with the removable solid or net bottom walls, because the wind wave suppression due to the bottom wall provides a small form drag that acts on the wind waves. Through the rearrangement of the previous wind and wave values measured in a Russian tank, the usefulness of the presented wind wave suppression method is demonstrated for future investigations of the air–water momentum and heat transport at extremely high wind speeds. Moreover, the method can be applied to clarify the effects of the fetch on the air–water momentum and heat transfer at extremely high wind speeds.
