El Niño: El Niño is the opposite of La Niña, where the surface waters of the Pacific Ocean become unusually warm. This can also lead to changes in weather patterns.
Thermocline: The thermocline refers to a layer in large bodies of water where there is a rapid change in temperature with depth. It plays a role in ocean circulation and affects marine life distribution.
ENSO (El Niño-Southern Oscillation): ENSO refers to both El Nino and La Nina events collectively. It describes the interaction between the ocean and atmosphere in the tropical Pacific, influencing global weather patterns.
