The ENSO cycle is a scientific term that describes the fluctuations in temperature between the ocean and atmosphere in the east-central Equatorial Pacific.
La Nina is sometimes referred to as the cold phase of ENSO and El Nino as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate.
These anomalies may have impact on crop production. In brief - La Nina results in a decreased crop yields, El Nino increases the yields. Growth crop yields will reduce the price and yield reduction gives us the opposite situation.
