Resumo
We study the stochastic problem of anomalous structures emergence on the sea surface. The kinematic boundary condition on the surface is assumed to be a closed stochastic quasi-linear equation. We derive an equation for a spatially single-point, simultaneous joint probability density of the surface elevation field and its gradient. We show the emergence of anomalous high structures on the sea surface almost in every realization of a stochastic velocity field.
