El nino or la nino environment global problems
Answers
Answer:
We know that there are many anthropogenic forcings on the climate, particularly the volume of carbon and greenhouse gases pumped into the atmosphere as a part of our everyday lives. Yet there are a number of natural processes that affect local weather, regional climate and global conditions. Some effects on our climate are a result of fluctuations and anomalies in the complex water conveyor belts of the ocean currents of the world. These fluctuations are known as “oscillations” and the two best-known oscillations are El Niño and La Niña (1) (2).
Explanation:
Both El Niño and La Niña are opposite effects of the same phenomenon: the ENSO (El Niño Southern Oscillation). Both are an oscillation in the temperatures between the atmosphere and the ocean of the eastern equatorial Pacific region, roughly between the International Dateline and 120 degrees west (2). El Niño - the conditions for which build up between June and December (15) - is caused by a change in the wind patterns (5). Here, the Pacific Trade Winds fail to replenish following the summer monsoons of Asia (7). This warmer air leads to an oscillation between the cooler and warmer waters, leading to warmer ocean temperatures than normal.
