Warm ENSO episodes result in abnormally wet conditions over northern Australia, Indonesia, and the Philippines in both winter and summer seasons. Answer: 8. During a warm ENSO episode, storms tend to be more vigorous in the Gulf of Mexico along the southeast coast of the U.S. resulting in wetter than normal conditions in that region. Answer: 9. During a La Nià ±a episode, higher than normal pressure is observed over Indonesia and northern Australia and lower than normal pressure is observed over the eastern tropical Pacific. Answer: 10. The southeastern U.S. becomes warmer and drier than normal during a cold La Nià ±a episode. Answer: 11. El Nino is closely related to global atmospheric oscillation known as the Northern Oscillation. Answer: 12. La Nià ±a represents the warm phase of the ENSO cycle and El Nino represents the cold phase of the ENSO cycle. Answer: 13. NOAA’s Climate Prediction Center declares the onset of an El Nià ±o episode when the 6-month average sea-surface temperature departure exceeds 2.5 deg Celsius in the east-central equatorial Pacific. Answer: 14. El Nià ±o and La Nià ±a episodes typically occur every 2-7 years. However, in the historical record this interval has varied from 3-5 years. Answer: 15.

Even broader than the size of the planet are the amount of changes and relationships between humans, animals, environment, weather, and the effects of each. Many times with busy schedules and modern lifestyles we forget the interaction that goes on between any number of concepts or ideas. We fail to realize that a specific weather occurrence in the Pacific Ocean can have an effect on every day life in the United States.

Global warming has a profound vast impact on the Earth. Besides landmasses, ocean is warmed unevenly. Additionally, unexpected changes in ocean current will aggregate the uneven distribution of water temperatures along the globe. Warmer or cooler than normal sea surface temperatures occur alongRead More El Nino: Past, Present, and Future Essay example1296 Words   |  6 PagesEl Nino: Past, Present, and Future El Nino is both an atmospheric and oceanic phenomenon affecting weather patterns all around the world. It is complemented by La Nina in a cycle that occurs approximately every 4 years, varying as much as every two years to every six years (Wang 1999, 3331). La Nina has almost the opposite effect, however differs in its strength and duration randomly, as does El Nino (Fedorov 2000, 1998). The cycle is often paraphrased as ENSO, standing for El Nino-Southern OscillationRead MoreEl Nino2863 Words   |  12 PagesStates. El Nino is one of the largest scientific phenomenons that scientists have ever explored. The main concepts of El Nino are very simple and there are many variations, causes, affects, and relationships to study. The main idea behind El Nino is that the wind changes direction across the Pacific Ocean. In a non El Nino year (normal), the trade winds blow from east to west across the ocean, from North and South America towards the tropical regions of the Pacific Ocean. In an El Nino year, theRead MoreWhat Makes El Nino?2005 Words   |  9 PagesEl Nino is a phenomena that occurs when the ocean and the atmosphere collide. The warm atmosphere mixes with the water and creates a moisture in the air creating a low pressure system. A high pressure system is created when the cold water reduces the air above it. During a low pressure system the air becomes moist and can create severe tropical storms, on the other hand when there is a high pressure system the cold dry air goes back down and takes away all of the moisture. When combined this canRead MoreThe El Nino Southern Oscillation1878 Words   |  8 Pages Introduction The El Nino Southern Oscillation is a large scale circulation of atmospheric and oceanic interactions. It is a natural climate phenomenon where the tropical Pacific Ocean experiences higher than normal ocean temperature. The opposite, La Nina, refers to the unusual cooler than normal sea surface temperatures. It gained its name â€Å"the Christ child† in Spanish (â€Å"the girl† for La Nina) because the characteristic is most obvious around Christmas alone the western coast of South AmericaRead MoreEl Nino And Its Effects852 Words   |  4 PagesEl Nià ±o and its Effects Recently, the weather has varied greatly from traditional for many areas within the United States; the East Coast has had next to zero snow, while Midwest states have been hit by several heavy snowstorms. Although this change in weather patterns, compared to the average year, may appear unordinary and confusing, it can be attributed to the fact that a very strong El Nià ±o is currently underway. El Nià ±o occurs when trade winds in the Pacific Ocean decrease in magnitude, whichRead More El Nino Essay1144 Words   |  5 Pages El Nino nbsp;nbsp;nbsp;nbsp;nbsp;Typically, the level of ocean water around the world is higher in the western Pacific and lower in the eastern, near the Western coast of South and North America. This is due primarily to the presence of easterly winds in the Pacific, which drag the surface water westward and raise the thermocline relatively all the way up to the surface in the east and dampen it in the west. During El Nino conditions, however, the easterlies move east, reducing the continuingRead MoreGlobal Warming As Causes Of El Nino Southern Oscillation Phenomena2540 Words   |  11 Pagesâ€Æ' ESSAY PLAN Global Warming As Causes Of El Nino-Southern Oscillation Phenomena The advancements in various sectors in the life of human beings, which often exploit natural resources without control, directly or indirectly lead to changes in the environment sustained effect unconsciously towards the emergence of a disaster.
