Abstract

Original article: Physics of Fluids 24 (10), 105110 (2012)
There is a sign error in our article1 concerning the calculations of the mean curvature H. If the normal vector is defined such that it points towards larger enstrophy values, as it is the case in Ref. 1, Eq. (A4) should read K = 4ac − b2, H = −a − c. From this, it follows that Figures 11–14 in Ref. 1 show the wrong sign for the mean curvature H. Positive and negative mean curvature values must be exchanged. Figures 11–14 in the paper should be replaced by Figures 1–4 below.
