In this paper we derive a decay rate of the L(2)-norm of the solution to the 2D dissipative quasi-geostrophic flows compared with the corresponding linear equation. Here, we establish a new, concise and direct method, which only relies on a rough decay estimate of parallel to del theta(t)parallel to(2)(L) and avoids using the Fourier splitting technique completely.
