Life cycles of agriculturally relevant ENSO teleconnections in North and South America

摘要

The characteristic evolution of El Nino Southern Oscillation (ENSO) on timescales of months to years means that risks to agriculture have structure between seasons and years. The potential for consecutive ENSO-induced yield anomalies is of particular interest in major food producing areas, where modest changes in yield have significant effects on global markets. In this study, we analyse how multi-year El Nino and La Nina life cycles relate to climate sensitive portions of major crop-growing seasons in North and South America.
