A Comparison of the Weather in U.S. Cities During the 1982–83 and 1997–98 El Niño's
Heather L. Honnette, U. S. Naval Academy, Annapolis, MD
The El Niño 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 for the winter months, December through March, are examined for fourteen cities across the United States. This study will explore the effects of the 1982-83 and 1997-98 El Niño's on these fourteen cities to determine the impact of El Niño on temperature and precipitation patterns across the nation. Monthly averages for each of the cities will be compared with the data from these two major El Niño events as well as with each event’s respective 30-year normals. This comparison and analysis will help determine the relative strength of these El Niño events and the magnitude of change they induced on normal weather conditions at stations throughout the country.
