Question

What process causes El Niño-Southern Oscillation events?

-increased movement of cold polar water from Antarctica?
-higher temperatures in the Pacific near Australia
-weak prevailing winds in the Southern Hemisphere
-drought conditions in South America

Answer 1

The process that causes El Niño-Southern Oscillation events is a combination of factors, including increased movement of warm ocean water from the central and east-central equatorial Pacific, higher temperatures in the Pacific near Australia, and weak prevailing winds in the Southern Hemisphere.

Step-by-step explanation:

The process that causes El Niño-Southern Oscillation (ENSO) events is a combination of factors, including increased movement of warm ocean water from the central and east-central equatorial Pacific,

higher temperatures in the Pacific near Australia, and weak prevailing winds in the Southern Hemisphere.

These events are also associated with drought conditions in South America.
