Difference Between El Nino and La Nina
El NiÃ±o vs. La NiÃ±a
When the temperature gets really hot, some believed it to be global warming, but it is not really. It is the infamous El NiÃ±o. El NiÃ±o is a Southern Oscillation, a phenomenon where the eastern central Pacific Ocean gets really warm. Sometimes El NiÃ±o is just called the ENSO or El NiÃ±o Southern Oscillation. The term El NiÃ±o was in honor of baby Jesus, because the warming usually is on all time high during December. This kind of phenomenon has a great effect on the weather conditions all over the world.
But El NiÃ±o did not come alone, after El NiÃ±o its little sister, La NiÃ±a, comes around too. La NiÃ±a is also a southern Oscillation. This time it is the cold episode of the Oscillation phenomenon. La NiÃ±a is the counterpart of ENSO. Though these two are both changes in temperature, these two have so many differences.
During the time of visit of these sibling phenomenons, they wreak havoc across the Pacific to the cost of South America claiming thousands of life, destroying hundreds of homes, and causing damage to a lot of crops and properties. Hurricanes and floods came together with La NiÃ±a and drought and dry lands came with El NiÃ±o. Some people confuse the two names. Here is a tip to know which is which. El NiÃ±o means ‘little boy’ it is the warm episode, while La NiÃ±a means ‘little girl’ the cold episode.
Now to differentiate the siblings, here are more facts to help you understand better. El NiÃ±o is when the ocean temperature in the Pacific until the coast of South America rises to .5 degrees Celsius and sometimes even higher. This phenomenon happens every two to seven years.
There are times when it is instantly followed by its sister La NiÃ±a, but not all the time. La NiÃ±a is exactly El NiÃ±o’s opposite. La NiÃ±a is the cold episode. The most significant La NiÃ±a was during the fall of the year 2000. EL NiÃ±o was most significant during 1997-98.
Up until now, scientists are still arguing on what really causes these phenomenons. There is still no concrete explanation why these significant changes in temperature take place. There are others who claim that it is because of the increases in the Western trade winds, there are also other theories stating that it may be because of the boiling water in the equator which are now spreading towards the sea. Another one tells that the motion of the atmosphere affects the water in the ocean which makes it heat up, just like how engine heats up when being revved up.
El NiÃ±o refers to the warm episode of the oscillation phenomenon, while La NiÃ±a is the cold episode.
El NiÃ±o means little boy while La NiÃ±a means little girl.
El NiÃ±o happens every two to seven years, while La NiÃ±a may or may not follow it after.
La NiÃ±a was most significant during the fall of the year 2000 while El NiÃ±o was most significant during 1997-98.
