On the optimal conditions for the focusing of giant sea waves
Abstract
The dynamics of a wave packet on a twodimensional sea surface, which is described by the nonlinear Schröbinger equation 2iψ_{t} + ψ_{xx} ‑ ψ_{yy} + ψ^{2}ψ = 0, has been analyzed within the Gaussian variational ansatz in application to the problem of the formation of rogue waves. The longitudinal (X(t)) and transverse (Y(t)) sizes of the packet are described by a system of differential equations:
