Abstract
In this paper, we investigate the two-dimensional rotating Navier−Stokes equations on a periodic β-plane, where the Coriolis parameter varying as βy, in the strip domain Ω=T×ℝ. Utilizing a horizontal space decomposition method, we demonstrate that the oscillatory component of the velocity v decays over time. Furthermore, we establish the global existence of strong solutions for this rotating system with horizontal dissipation only. In addition, we prove that the oscillatory part of the velocity decays exponentially to zero in the H1 norm as t→∞.
