ANALYSIS OF OBSERVATIONS AND METHODS FOR CALCULATING
HYDROPHYSICAL FIELDS IN THE OCEAN
METHODS FOR PROCESSING THE DATA OF WIND-PROFILE OBSERVATIONS
OVER THE OCEAN
N. A. Timofeev
We describe the in-line methods for processing the results of observations of the vertical distri-
bution of wind speed with an aim of evaluation of the parameters characterizing the stable state
of the surface layer of the atmosphere and the roughness of the sea surface. It is proposed to use
these data for the interpretation of the results of satellite scatterometric measurements of the sur-
face wind speed in order to increase their accuracy.
In the investigation of the processes determining the interaction of the ocean with the atmosphere, an im-
portant role is played by the parameters characterizing the stable state of the surface layer of the atmosphere and
the roughness of the sea surface caused by the action of winds and waves. These data can be useful for the inter-
pretation of the results of satellite scatterometric measurements of the surface wind speed and the analysis of the
processes of momentum, heat, and moisture exchange on the water–air interface. In what follows, we consider
Laikhtman Power Formula
The proposed method is based on the solution of the following equation introduced as a modified version of
the power formula [1, 2]:
are, respectively, the wind speeds on an arbitrarily chosen layer z
and on a fixed layer z
dynamic roughness of the sea surface, and ε is a parameter of stability of the lower (surface) layer of the atmo-
