The mechanism of IW generation by a turbulent plume has been proposed by
Troitskaya et al. [39], while a detailed theoretical analysis can be found in Bondur
et al. [10] and Ezhova et al. [20, 21] part 1, 2. To explain the observed phenomenon
a hypothesis of self-sustained oscillations was suggested. The amplitude of the
self-sustained oscillations is known to be described by the Landau equation
[20, 28]:
Fig. 3 Top panel: Cross section of isotherm oscillations at an outflow velocity of 150 cm/s.
Bottom panel: Spectra of isotherms in the thermocline region at an outflow velocity of 150 cm/s.
Different curves correspond to different depths
