El Nino (the warm phase of ENSO) is characterized by:
- AA type of fog
- BRecord cold in the equatorial Pacific
- CNo change to normal conditions
- DAnomalously warm sea-surface temperatures in the central/eastern equatorial Pacific, altering global weather patterns✓ Correct

During El Nino the central and eastern equatorial Pacific is unusually warm, weakening the trade winds and shifting rainfall and storm tracks worldwide (e.g., changes in Pacific and Atlantic hurricane activity and regional rainfall). La Nina is the opposite, cool phase.
