NASA Explains 'Dust Bowl' Drought


NASA scientists have an explanation for one of the worst climatic events in the history of the United States, the "Dust Bowl" drought, which devastated the Great Plains and all but dried up an already depressed American economy in the 1930's.

Siegfried Schubert of NASA's Goddard Space Flight Center, Greenbelt, Md., and colleagues used a computer model developed with modern-era satellite data to look at the climate over the past 100 years. 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.



AMO and PDO are to blame just like I wrote the other day. How warmers blame global warming is just lazy ignorance.
 
From the NASA link:

The model showed cooler than normal tropical Pacific Ocean temperatures and warmer than normal tropical Atlantic Ocean temperatures contributed to a weakened low-level jet stream and changed its course. The jet stream, a ribbon of fast moving air near the Earth's surface, normally flows westward over the Gulf of Mexico and then turns northward pulling up moisture and dumping rain onto the Great Plains. As the low level jet stream weakened, it traveled farther south than normal. The Great Plains dried up and dust storms formed.
 
wasn't the dust bowl caused by excessive agriculture?

No. That might have been the conventional wisdom at some point, but further study reveals the oceans were more to blame than human agricultural methods, and, though they may have made it worse, they were destined to endure the drought conditions. Read the nasa link I provided.
