Regional Temperature Response by ENSO Phase
| ENSO Phase | Condition | Hanoi Mean Anomaly | HCMC Mean Anomaly |
|---|---|---|---|
| El Niño | ONI ≥ +0.5°C | +0.56°C | +0.48°C |
| Neutral | -0.5°C < ONI < +0.5°C | +0.17°C | +0.06°C |
| La Niña | ONI ≤ -0.5°C | -0.36°C | -0.25°C |
★ El Niño events induce pronounced warming across Vietnam with a 3-month lag, strongest in southern tropical latitudes.
