Pdf - El Nino Normal Illingworth

The "El Nino Normal Illingworth PDF" is likely a specific chapter, appendix, or standalone technical report written by a researcher named A. Illingworth (or similar variation) that defines the "normal" or neutral baseline parameters for ENSO prediction. It may have been hosted on a university server (perhaps in Colorado or Queensland) and has since moved, becoming a "ghost document" in search algorithms. Part 2: The Scientific Importance of the "Normal" in El Niño Why is the word "Normal" so critical in this PDF? To appreciate this, we need to understand how El Niño is measured. The Oceanic Niño Index (ONI) NOAA defines El Niño based on a 3-month average of sea surface temperature anomalies in the Niño 3.4 region (5°N-5°S, 120°-170°W). The threshold is +0.5°C or higher. But +0.5°C compared to what ? Compared to the "normal."
