INTRODUCTION
EL NINO/LA NINA AND ITS EFFECT ON GLOBAL WEATHER
This report is on the weather phenomena known as El Nino and La Nina and how they affect weather patterns globally.
El Nino is known as the El Nino Southern Oscillation (ENSO) because of the strong link discovered between the air pressure in Darwin, Australia and Tahiti. It is basically a disruption of the entire oceanic atmospheric system in the tropical Pacific Ocean.
Not as much is known about La Nina because it occurs one third as much as El Nino and studies on it didn t really begin until the 1980s. La Nina is also known as an ENSO cold event and/or La Viejo (old man), and it basically amplifies normal weather patterns in a region.
Due to increased scientific studies and predictions, these events aren t as catastrophic as in the past because people can be forewarned about the event and adequately prepare for it.
