We prove that given initial data , forcing and anyT> 0, the solutionsuνof Navier‐Stokes converge strongly in for anyp∈ [1, ∞) to the unique Yudovich weak solutionuof the Euler equations. A consequence is that vorticity distribution functions converge to their inviscid counterparts. As a by‐product of the proof, we establish continuity of the Euler solution map for Yudovich solutions in theLpvorticity topology. The main tool in these proofs is a uniformly controlled loss of regularity property of the linear transport by Yudovich solutions. Our results provide a partial foundation for the Miller‐Robert statistical equilibrium theory of vortices as it applies to slightly viscous fluids. © 2020 Wiley Periodicals LLC.
