Oscillating wave packets (breathers) are a significant part of the dynamics of internal gravity
waves in a stratified ocean. The formation of these waves can be provoked, in particular, by the decay
of long internal tidal waves. Breather interactions can significantly change the dynamics of the wave
fields. In the present study, a series of numerical experiments on the interaction of breathers in the
frameworks of the etalon equation of internal waves—the modified Korteweg–de Vries equation
(mKdV)—were conducted. Wave field extrema, spectra, and statistical moments up to the fourth
order were calculated.
