Abstract:

The error of the wind speed determining by means of optical scanners, caused by the variety of physical factors forming topographic structure of the sea surface, is analyzed. It is shown that this error consists of two components. The first one is caused by the stochastic nature of a relation between wind speed and energy of short surface waves, it does not depend on the average wind speed and has a value of 0.2 m/s. The second one is due to deviation of the sea surface slope distribution from Gaussian; it increases with wind speed, varying from 0.1 m/s when the wind speed is 1.5 m/s to 0.4 m/s when the wind speed is 15 m/s.

Keywords:

sea surface slopes, wind speed, measurement error
