Когда принимаются во внимание слабые воздействия вращения Земли и поперечных возмущений, то уравнение изменяется к форме так называемого модифицированного уравнения Кадомцева—Петвиашвили с вращением. В этой короткой статье дана ревизия асимптотической процедуры вывода этого уравнения с учетом фонового сдвигового течения так же, как и фоновой стратификации.</p></abstract><trans-abstract xml:lang="en"><p>The Korteweg—de Vries equation is a standard model for the description of long nonlinear internal waves in the ocean. When the effect of weak transverse variations and the Earth's background rotation are taken into account, this is replaced by the rotation-modified Kadomtsev—Petviashvili equation. In this short note we revisit the asymptotic derivation of this equation, incorporating a background shear flow as well as the background stratification. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>солитоны внутренних волн</kwd><kwd>уравнение Кадомцева—Петвиашвили</kwd><kwd>уравнение Островского</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Internal solitary waves</kwd><kwd>Kadomtsev—Petviashvili equation</kwd><kwd>Ostrovsky equation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Grimshaw R.
