SPECTRAL METHOD IN THE INVESTIGATION OF INTERNAL WAVES,
Abstract
Measurements of temperature, density, winds, atmospheric pressure and currents made at three synchronous stations through August 1958 at North-East of the Atlantic Ocean were used to investigate internal waves. Internal waves are considered to result from the effect of tide-inducing forces on the oceanic water depth, and from dynamic interaction of the atmosphere and hydrosphere. The internal waves were investigated from the point of view of the theory of random function. Three types of internal waves are pointed out: (1) tidal - periods 12, 4 and 24 hours; (2) inertial - 14, 7 hr; (3) of meteorological origin or internal meteorological waves - 69-80; 31, 4; 18, 4 and 6 hr. Wind and the atmsopheric pressure as well as composite and residual currents have periods analogous or close to those of internal waves. The period of 14, 7 is the most important one for the surface layer of internal waves and currents, while in both cases semidiurnal periods are of great importance in discontinuity layer. (Author)
