The El Nino phenomenon has been shown to have a dramatic effect on the weather of locations worldwide. This air-sea interaction over the Tropical Pacific alters atmospheric wave patterns, thereby changing the movement of storm tracks, which modifies normal weather patterns. In this study, the temperature and precipitation observations are examined for fourteen cities across the United States. This study will explore the effects of the 1982-83 and 1997-98 El Nino's on fourteen different cities across the nation to determine the impact on temperature and precipitation patterns. Monthly averages for each of the fourteen cities will be compared for these two major El Nino events as well as against the 30-year normals for each of the cities, in order to determine the relative impact of these El Nino events and the magnitude of the deviations from normal conditions.
