Abstract

Values for the shear stress Ο„~0~ of the wind on a water surface, found in seven later experiments, are compared with the data of Francis (1951). Four sets of the new data show that the stress coefficient C = Ο„~0~/Ο±u^2^ is not constant, but that it increases somewhat with windspeed u (Ο± = air density). Three sets merely show a large experimental scatter of C, and do not support any consistent law of drag. A theory is also discussed that Ο„~0~ is mainly caused by the drag of the small ripples, and not by the drag of the big waves.

## Abstract A monolayer on a water surface is affected by the action of wind, and retracts until the wind drag is counter‐balanced by the opposing surface pressure gradient. This effect has been used to determine the shearing stress on water at low wind speeds. Estimates of the drag coefficient hav

## Abstract The form drag of wind on an irregular surface is found to equal the product of __U__^2^ (__U__ is anemometer wind‐speed) and a function of the two‐dimensional spectrum of this surface. For a solid surface this function is, of course, independent of __U__ and the form drag is proportiona
