I definitely agree with you and raindance on this....the largest issue I see with people, including myself, is that our stances tend to be too polarized. This causes us to view issues as too "black and white", when the reality is much more nuanced and more of a compromise. I definitely see some summer-season commonality with stronger el nino events, such as 1972, 1982, 2009 and 2015, but I think its also important to consider the -vp pattern and MEI/RONI because those metrics also offer insight into the overall character of the developing el nino event. There are some stark differences between those 4 seasons.
Dismissing how the forcing is manifesting itself is every bit as silly and equally detrimental to seasonal forecasting efforts as failing to fully appreciate the existence of an appreciable nino.
