FEWS NET: Historic ENSO-Related Climate Impacts

Type of ENSO Event:   Region:  Season:


  • Dataset Used:
  • Method:
    • Frequency of above- (>66th percentile) and below- (<33rd percentile) average precipitation and temperature for three-month seasons related to El Nino and La Nina. Only the dominant category is shown at a gridpoint.
    • Percentiles are calculated relative to 1950-2022, the period of record for ENSO events.
    • Dry mask (light purple) is applied when seasonal mean precipitation during 1950-2022 is less than 20 mm.

    • The Famine Early Warning Systems Network (FEWS NET) is a leading provider of early warning and analysis on acute food insecurity around the world.
    • FEWS NET draws heavily on agroclimatological analysis to monitor and construct scenarios of food security in the countries it covers. While food security depends on a complex variety of factors, climate and weather shocks often play a significant role in episodes of acute food insecurity.
