Answer

Cooler and wetter conditions in the Pacific Northwest in the USA Explanation 1. Understanding La Niña's Climate Effects La Niña is a climate pattern characterized by cooler-than-average sea surface temperatures in the central and eastern Pacific Ocean, which influences global weather patterns, especially in North America. 2. Evaluating Each Option - "Warmer and drier winters in the Pacific Northwest in the USA": This is incorrect; La Niña typically brings cooler and wetter conditions to this region. - "Increased rainfall in the southwestern United States": This is incorrect; La Niña usually causes drier conditions in the Southwest. - "Cooler and wetter conditions in the Pacific Northwest in the USA": This is correct; La Niña leads to more precipitation and lower temperatures in the Pacific Northwest. - "Decreased hurricane activity in the Atlantic ocean": This is incorrect; La Niña tends to increase hurricane activity in the Atlantic due to reduced wind shear. 3. Selecting the Correct Impact The most typical impact of La Niña on North America is cooler and wetter conditions in the Pacific Northwest.
