Answer

Answers: 1. Trade winds of the South Pacific weaken and may even reverse direction 2. A low pressure system forms over the Eastern South Pacific 3. Upwelling of colder ocean waters slows down near South American Coast Explanation: ENSO occurred in three phases, but it is a single phenomenon related to climate. Three phases are El-Nino, La-Nino and neutral. El-Nino occurs in irregular interval of two to seven years and lasts for nine months to two years and left its catastrophic impact on Peru, Chile and Australia among other countries. Whereas, La- Nino occurs between two El-Nino events and trigger the hurricane activity in the Atlantic. Other than El-Nino and La-Nino neutral condition exists throughout the year The El Nino Southern oscillation is generally associated with the upward movement of oceanic currents. The trade winds move westward, and low pressure is created above the western South Pacific waters.
