How do we know that the #ElNino phase has arrived?
We use our instruments:
“Satellite- and ocean-based measurements of sea surface temperature are one way to detect the arrival of El Niño. Its signature also shows up in satellite measurements of sea surface height, which rises as ocean temperatures warm up. That’s because warmer water expands to fill more volume, while cooler water contracts.
The [image] depicts sea surface height anomalies across the central and eastern Pacific Ocean as observed from June 1–10, 2023. Shades of blue indicate sea levels that were lower than average; normal sea level conditions appear white; and reds indicate areas where the ocean stood higher than normal.”
