Large-scale atmospheric circulations and anomalies have been shown to have a significant impact on seasonal weather over many parts of the world. In this paper, the impact of large-scale atmospheric and oceanic anomalies on the Indian monsoon are analyzed with particular reference to El Niño/Southern oscillation (ENSO) events of the last hundred years.A possible link between ENSO, Indian monsoon and grain yields is investigated by analyzing world-wide grain yield data in conjunction with ENSO event and floods and droughts in the Indian monsoon. It is found that an ENSO event is generally associated with a drought in the Indian monsoon followed by a low grain yield over South Asia and Australia and high grain yield over the north American prairies. Implications of this analysis for estimating world grain yields in advance are considered.
