<abstract>Existence is proved for dissipative subcritical 2D quasi-geostrophic flows with a specific pointwise behavior in space-time. First we treat flows with small initial data, employing only elementary estimates for convolution integrals. Our results extend those proved in [7] and [12] for 2D Navier--Stokes flows. We then prove the specific space-time behavior mentioned above is also interpreted in a framework of $L^p$-like function spaces with $2/3\leq p\leq\infty$.</abstract>
