Trans-Pacific ENSO teleconnections pose a correlated risk to agriculture
Agricultural and Forest Meteorology(2018)
摘要
Schematic of life-cycles of ENSO teleconnections for the La Niña life cycle, in which a La Niña is preceded by an El Niño and followed by a second year of weaker La Niña conditions. Black arrows indicate robust teleconnections to crop flowering seasons. Grey arrows indicate weak teleconnections. Dotted arrows indicate no teleconnection. Ocean colors indicate the intensity of either cold SST anomalies (blue) or warm SST anomalies (red). Tropical Pacific SST anomalies develop in JASO, peak in NDJF, and decay in MAMJ. While atmospheric teleconnections are strongest in NDJF, there are fewer crop flowering seasons in these months compared to JASO or MAMJ
