Abstract: This paper investigates the ergodicity and weak convergence of transition proba- bilities for two-dimensional stochastic primitive equations driven by multiplicative noise. The existence of invariant measures is established using the classical Krylov-Bogoliubov theory. The uniqueness of invariant measures and the weak convergence of transition probabilities are demonstrated through the application of the asymptotic coupling method and Foias-Prodi estimate.

Key words: stochastic primitive equations, invariant measure, ergodicity, weak convergence of the transition probabilities, asymptotic coupling method, Foias-Prodi esti-mate.
