    Solution

    The La Nina is the "cool phase" of the El Nino-Southern Oscillation (ENSO), which is a natural climate pattern that occurs in the Pacific Ocean.  La Nina is caused by a build-up of cooler-than-normal waters in the tropical Pacific, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn.
