About
RONI is NOAA's Relative Oceanic Niño Index. A period's phase is its mean RONI: ≥+0.5 positive (El Niño), ≤−0.5 negative (La Niña). Each observation is one harvested season's CEC yield — observed history only, no forecasts.

About
Each bar: how strongly that month's satellite signal has correlated with the final yield across the recorded seasons. The dashed purple line is the month-weight table used by the condition index — the bars are its justification.
