We live on an incredibly large planet. Even broader than the size of the planet are the amount of changes and relationships between humans, animals, environment, weather, and the affects of each. Many times with busy schedules and modern lifestyles we forget the interaction that goes on between any number of concepts or idea's. We fail to realize that a specific weather occurrence in the Pacific Ocean can have an affect on every day life in the United States. 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…show more content…
The most recent El Nino years were 1982-1983, 1991-1992, 1994-1995, and 1997-2000. The longest recorded El Nino activities in the last 50 years occurred between June 1998 – May, 2000. Although sometimes being very mild, ENSO was still present. Every El Nino occurrence varies in some way such as the magnitude, duration, or measured causes around the globe (NOAA C, 2004). The reason that ENSO is documented and measured in the Pacific Ocean instead of any other ocean seems to be for one main reason: the overall size of the Pacific as compared to the Atlantic or Indian Oceans (Daly, 2004). The size of the Pacific Ocean allows the water to swell in size and temperature as it moves in one direction or another. There are similar occurrences in the Atlantic and Indian Oceans, but there is not enough space for the water and wind to become large enough to make a significant impact. There are several general environmental patterns that are dictated by El Nino and La Nina. The first is tropical storms and hurricanes. The National Oceanic and Atmospheric Administration (2004) states that during El Nino year's tropical storms and hurricanes develop easier and more often in the Pacific Ocean than in a normal non ENSO year. At that same time, tropical storms and hurricanes occur less frequently and seem to be less drastic in the Atlantic
