SummaryA laboratory wind tunnel has been used to study the effect of wind on a water surface. The surface shearing stress 7'0 and the slope of the surface induced by wind have been measured. Values of the surface stress, in good agreement with each other, have been obtained from: (a) the velocity profile of the wind above the water surface, (b) the measured values of surface slope or set-up, and (c) the spreading characteristics of surface films. The drag coefficient, C h = TO/ pU~, was found to be constant for wind speeds up to about 412 cm/s and then to rise gradually for higher wind speeds.When the surface waves are damped out by the addition of small amounts of surface-active material to the water, the shearing effect of the wind on the surface is somewhat modified. If detergent solution is used for this purpose, there is a critical concentration at which conditions in the boundary layer near the water surface appear to undergo a marked change in character.

The downwelling velocities associated with Langmuir circulations in Lake Ontario correlate well with wind speed under surface cooling. With surface heating the correlations with wind speed are poor and calculations of a stabihty parameter indicate a different proportionality.Observations of surface phenomena indicate that surface slicks and capillary wave damping arc in operation at the point of downwelling.

Influence of the sea surface temperature on the stratification of airmass and cumulus activity over the East China Sea in the pre-summer rain season is studied on the basis of data of Experiment of Severe Rainstorms Research Project. While the very warm water is distributed over the Kuroshio region in the southeastern part of the East China Sea, there is a cold water pool in the central part of the East China Sea.The conditional unstable stratification of the subtropical airmass, which flows over the cold water pool, is modified into a very stable stratification.The airmass, which flows over the Kuroshio region, on the other hand, maintains its conditional instability. The airmass modification over the cold water pool is simulated in the simple numerical experiment with equations of heat and moisture diffusion. The influence of the sea temperature on the cumulus activity is examined by a statistical analysis of the radar echo distribution. The result of the analysis shows that cumulus convections are suppressed over the cold water pool.
