Abstract

In this paper, we study the averaging principle for 2D Boussinesq equations with non-Lipschitz Poisson jump noise. Precisely, we will first explore the well-posedness, regularity estimates and tightness of the vorticity variable. Then, we prove the ergodicity of the temperature variable. Next, we prove that the vorticity variable converge to the solution of the averaged equation in probability and 2p2pth-mean, under different conditions, as time scale parameter ε\varepsilon goes to zero. Finally, we present a specific case study and conduct numerical simulations to substantiate the main conclusions of this paper.
