Final answer:
The conditions related to strong El Niño events are hurricanes, higher sea levels, and an increase in sea-surface temperature.
Step-by-step explanation:
The conditions related to strong El Niño events are:
- Hurricanes: Strong El Niño events can influence the number and intensity of hurricanes in certain regions. For example, El Niño can suppress hurricane activity in the Atlantic basin but enhance it in the Pacific.
- Higher sea levels: During El Niño events, higher sea levels are observed along the coasts of some regions due to various factors like changes in atmospheric pressure and wind patterns.
- Increase in sea-surface temperature: El Niño events are characterized by a significant increase in sea-surface temperature in the central and eastern equatorial Pacific Ocean.
