Final answer:
The weather pattern that brings cooler temperatures to the Pacific region is La Niña. This pattern involves the cooling of the equatorial Pacific Ocean which affects global weather patterns.
Step-by-step explanation:
The weather pattern that brings cooler temperatures to the Pacific region is La Niña. Unlike El Niño - which is associated with warmer temperatures, La Niña is the term used to describe the cooling of the equatorial Pacific Ocean. This cooling affects global wind and weather patterns and tends to cause cooler temperatures in the Pacific region. La Niña is, therefore, the correct answer to this question.
