Which of the above phenomena is characterized by a periodic warming of sea surface temperatures in the central and eastern tropical Pacific Ocean? Answer:
Only 1
Notes:
El Niño is a climate phenomenon marked by the warming of ocean surface temperatures in the central and eastern Pacific, influencing global weather patterns. It typically occurs every 2 to 7 years and can lead to increased rainfall in some regions and droughts in others.
La Niña, the counterpart, involves a cooling of these ocean temperatures and generally results in opposite weather effects.
Jet streams are fast-flowing air currents in the atmosphere that can shift weather patterns but are not directly classified as an oceanic phenomenon like El Niño or La Niña.
