Here is part 2 of a conversation on QBO with Roundy from yesterday. I tend to interrupt these meteorology Twitter threads by throwing out comments relating to what I am finding. These arguments usually play out by this analogy: Say that someone like Roundy was analyzing an electrical signal. I am simply pointing out that there is an obvious 60 Hz hum that is emerging in the signal, and I am suggesting a possible source of that signal. Then Roundy responds with that can't happen because there are other sources of noise in there as well. I come back and say that those other noise sources aren't going to eliminate the 60 Hz hum. Then he comes back and asserts that it is more complicated than that, because if that was the case, all the models would fail.
