Question

What is El Niño? Identify at least two ways in which El Niño changes the weather of a region. Be sure to write your response in three or more complete sentences.

Answer 1

Answer:

"El Niño" is a normal cycle ocurrence of change in temperatures in the surfaces of the central equatorial, and east equatorial waters of the Pacific Ocean. It is part of a normal phenomenon in climate change called the El Niño-Southern Oscillation (ENSO). The particular cycle of El Niño, is the warm side of the two cycles, which are El Niño and La Niña.

The result, however, of this phenomenon taking place on the surfaces of the Pacific Ocean, is a change on the climate temperatures around the globe, and also the development of weather changes that will affect different parts of the world in different ways. In some, like in the countries nearest to the equator, it brings higher temperatures, and less rainfall, while in others, it brings out heat waves, winter waves, etc.

It is important to know that although the phenomenon that makes part of the Southern Oscillation is a normal process that has been happening since prehistoric times, the fact of global warming, which has caused the changes in temperatures in the oceans, has unchained the effects of the El Niño phenomenon but at a much stronger level. Thus we are now seeing higher formation of hurricanes and cyclones, winter seasons  extending beyond their normal time, and heat waves and dry seasons extending beyond what they should be.

Answer 2

EL Nino is an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador, typically in late December.
