There are two minor flaws in our 2017 paper. The first flaw is in the proof of Lemma 2.7, which relates a generalization of Helmholtz-Weyl decomposition on a closed surface. The second one is in Appendix (I), where we compare our model to Taylor's model when the surface does not move. We give a full proof of Lemma 2.7 as well as a correct comparison of our model with Taylor's model (1992). It will be properly interpreted.
