Micro-meteorological Observations over the Sea (1)

Abstract

Wind speed, air and water temperatures, vapour pressure, net incoming radiation from the sun and the sky were observed near the sea surface.
Wind speed observations show that when the wind speeds at 6.1 m height are lower than 5 m·sec^-1, no kinks can be seen in their profiles, but when they exceed 7 m·sec^-1, kinks can be seen at 0.6-1.1 m heights above the sea surface. These two types of profiles are chosen by the state of the sea surface and wind speed.
The wind observations also support the relation z₀=u*² / (ag) as suggested by CHARNOCK.
The individual time change of water temperature was mostly explained by the residual, which is the heat remainder by subtracting the sensible and evaporation heat from the net incoming radiation to the sea surface.
