The El Niño weather phenomenon has a large affect on the climate of regions around the world. El Niño has influenced storm tracks, weather patterns, temperature and precipitation. In this study, weather charts, temperature, precipitation and other observations will be examined for fourteen U.S. Cities in order to chart the effects of the 2002-2003 El Niño. The monthly averages of these cities will be compared to the El Niño of this year and previous El Niños. In addition, the MEI (Multivariable ENSO Index) of the 2003-2003 El Niño will be examined at the cities of interest to better understand the correlation between the index and the observed weather. The month of February 2003 will be examined in particular due to its unusually unseasonable and extreme weather. The result will be a better understanding and explanation of the weather associated with 2002 -2003 El Niño season.
