El Niño Global Temperature Simulator

PACIFIC OBSERVATION DECK ENSO CYCLE 3.4

Historical & Current Presets

Niño 3.4 SST Anomaly +2.2°C

Sea Surface Temperature departure from 1991–2020 baseline (ONI threshold: +0.5°C = El Niño, +2.0°C = Very Strong).

Equatorial Trade Wind Anomaly -3.5 m/s

Weakening of easterly trade winds collapses upwelling, triggering rapid oceanic heat release to atmosphere.

Equatorial Heat Content Anomaly 142.5 ZJ

Upper 300m heat content anomaly (ZettaJoules, 10²¹ J) feeding global surface temperature acceleration.

GLOBAL TEMP ANOMALY

+1.48°C

Above pre-industrial baseline

Climatological Mechanism: An unfolding El Niño redistributes immense Pacific thermal energy into the atmosphere. Weakened easterly trade winds diminish the equatorial thermocline slope, halting deep cold water upwelling and amplifying global surface temperature anomalies over a 3 to 9 month lag.
