I am not sure I have studied this question exactly, but let me tell you what I said in my GRL article. The NPM mode of SST gets large and positive during the summer of 2013, about May. This is before the winter of 2013-14. The NPM anomaly has stayed large at least through January of 2015. I expect it to give way eventually. If it stays for another winter, that will be a real news story, I think.
