Q: Which ocean is most affected by La Nina?

Arab Weather - The ocean most affected by the La Niña phenomenon is also the Pacific Ocean, especially in its tropical part. During La Niña, ocean surface temperatures drop abnormally in the eastern tropical region of the Pacific Ocean. This phenomenon leads to the opposite effects of the El Niño phenomenon, as it causes heavy rains in Australia and Indonesia and drought on the west coast of South America.

La Niña also affects global weather patterns, increasing hurricane activity in the Atlantic Ocean and bringing colder winters to certain areas such as the United States.
