Here are responses from Dr. McIntosh: That’s why it’s called a scatterplot - it (the relationship) a representation or abstraction of what’s going on. The relationship has to weight all of those maxima and find something that tries to make sense with the various counting errors. Also - the relationship is based on a 13-month averaged value - not my choice but the common measure in the field and one that masks a lot of stuff… I’m not going to hand fit the relationship to match better a few cases that seem like systematic outliers. data is taken from SILSO - see the website. There hasn’t yet been a monthly mean of that magnitude - I was most likely referencing daily values in a sarcastic manner. Post terminator that plot will have to be rescaled.
