The Pacific Weather Phenomenon is a term used to describe two distinct weather patterns that occur in the Pacific Ocean. The first is La Niña, which is characterized by unusually cold ocean temperatures in the equatorial Pacific. This can lead to increased rainfall in some areas and drought in others. The second is El Niño, which is characterized by unusually warm ocean temperatures in the equatorial Pacific. This can lead to increased rainfall in some areas and drought in others. Both of these phenomena can have a significant impact on global weather patterns.
