In 2004 NASA's Siegfried Schubert discovered how ocean temperature anomalies caused the dust bowl drought in the Great Depression.
The study found cooler than normal tropical Pacific Ocean surface temperatures combined with warmer tropical Atlantic Ocean temperatures to create conditions in the atmosphere that turned America’s breadbasket into a dust bowl from 1931 to 1939. ...
These changes in sea surface temperatures created shifts in the large-scale weather patterns and low level winds that reduced the normal supply of moisture from the Gulf of Mexico and inhibited rainfall throughout the Great Plains.
The sea surface temperature anomaly patterns that caused the dust bowl drought have returned.
