Thirstwave

Researchers have coined a new term to describe extended periods of atmospheric thirst called Thirstwaves.

About Thirstwave

  • A thirst wave has at least three consecutive days when daily evaporative demand is greater than its historical 90th percentile value for that period.
    • Evaporative demand is a measure of how thirsty the atmosphere is.
  • A combination of factors drives evaporative demand, including temperature, wind speed, humidity, and sunshine.
  • Studying these ‘thirstwaves’ can help farmers better manage their water resources and improve crop yields.
