A Science feature dated April 17, 2020 describes how drought forecasting models from UC Santa Barbara's Climate Hazards Center predicted a severe drought in southern Africa after ocean temperature shifts in late 2019. The models anticipated stunted maize growth in Zimbabwe by January, and the article covers the famine early-warning work behind the forecast.

After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
