Abstract
The association between climatic anomalies in the tropical Pacific Ocean, often called El Niño events, and annual corn production in the United States was investigated. Temperature and atmospheric pressure in parts of the United States have been correlated with El Niño events. This research suggests that in years in which an El Niño event causes surface temperatures in the tropical Pacific to become warmer than normal, there is a higher probability of an above-average corn crop in the United States. For years when sea surface temperatures are average or cool, no significant association is observed.
