The 1982–83 El Niño event was described as one of the worst disasters in the history of Peru.[1] It is only one of only three El Niños to be classified as a Very Strong El Niño on the Oceanic Niño index.[2] Anywhere between 512[3] and 596[4][5] people were killed as a direct result of the event, with a further 8,500 dying in the aftermath of the El Niño.[3]
Meteorological background
[edit]The signs of an El Niño began to appear in early 1982, when a noticeable and measurable drop in atmospheric pressure was noted in the central and southeastern Pacific compared to pressures found off the coast of Darwin, Australia.[6] As the year progressed, more and more signs pointed towards an upcoming powerful El Niño event; from the collapse and subsequent reversal of the trade easterlies that traditionally prevent upwelling from occurring in the Western Pacific[7] to the various atmospheric signatures associated with the El Niño–Southern Oscillation.[6]
