✦ Synopsis

The resonant generation of a second-mode inter-Nmax nal solitary wave, resulting from a ship internal waves Re system damping in a thermocline, is studied experimen-Fi tally. The source of the stationary internal waves was pro-fn vided by an oblong ellipsoid of revolution towed horizontally and uniformly at the depth of the thermocline center, con The ranges of the Reynolds and Froude numbers were kn 500~Re=Ul/v~15000 and 0.3~Fi=U/NmaxD~l.O, respect-C. ively. When the body's speed and the linear long-wave second-mode phase speed were equal, an internal solitary wave Ur of the "bulge" type was observed. The shape of the wave v satisfied the Korteweg-de Vries equation. The Urcell parameter a was equal to 10.2.
