Abstract
Wind profile measurements in the lowest layers above the sea surface under conditions of stable stratification are presented which have been performed" using floating buoys" during a cruise in the Baltic in April 1964. It is shown that the "log + linear profile law proposed by Monin and Obuchow holds well even in the more stable range. Using a rough estimation of the Monin-Obuchow length L′ =L . KH/KM the author obtains a value of α′ = α . KH/KM which increases from 6 to 9 with increasing stability. Friction velocity is also computed from the wind profiles employing the log + linear law, and presented in terms of the drag coefficient. It turns out to depend on the thermal stratification, decreasing with increasing stability.
