On linear internal waves on the sea, strongly vertically trapped

R. PURINI, E. SALUSTI

Abstract


We study some explicit cases of marine thermocline. We
focus our attention on the strongly vertically trapped internal waves, which
in our cases allow an explicit dispersion relation and a simple behaviour in
terms of elementary functions. The explicit form of the Vaisala-Brunt frequency
N2{z) is proportional to 1 / \z—20| in one case and to A2—B2(z—zD)2
in the other. A comparison with some experimental data concerning the
Ligurian Sea is actually in course.
