The dynamics of waves interacting with the Equatorial Undercurrent

A Constantin, RS Johnson - Geophysical & Astrophysical Fluid …, 2015 - Taylor & Francis
We propose a new, simple model–but one which has far-reaching consequences–to
describe the interaction between waves that propagate across the Pacific Ocean and the …

On three-dimensional Gerstner-like equatorial water waves

D Henry - … Transactions of the Royal Society A …, 2018 - royalsocietypublishing.org
This paper reviews some recent mathematical research activity in the field of nonlinear
