All three reviewers has a positive view of this paper and recommended publish after minor revision. To me this seems an interesting paper and having looked at your responses to the reviewers and the revised manuscript I am pleased to accept it for publication in ACP.

One minor point I raise myself is that it seems a little odd to talk about a 'midlatitude PV intrusion' (even if it is meant to be tacitly understood that 'midlatitude' refers to the origin of the PV rather than the location of the PV anomaly when it gives rise to the tropical temperature response) -- Figure 9 of the Taylor et al paper, for example, suggests that it is only the PV distribution equator ward of about 20 degrees that plays a significant role. You may agree (and change 'midlatitude') or disagree (and leave things as they are).

Finally there are a number of small mistakes in spelling etc -- e.g. 'gravitationnal' l21p12, 'additionnal' l20p25. In principle these sorts of things should be picked up by the copy editing by you might want to do a further check yourself.
