Well-posedness Properties for a Stochastic Rotating Shallow Water Model

Abstract

In this paper, we study the well-posedness properties of a stochastic rotating shallow water system in which the noise is chosen according to the Stochastic Advection by Lie Transport (SALT) theory. The system is perturbed by noise modulated by a function that is not Lipschitz in the norm where the well-posedness is sought. We show that the system admits a unique maximal strong solution which depends continuously on the initial condition. We also show that the interval of existence is strictly positive and the solution is global with positive probability.
