Precipitation • Percent of Normal, 180-Day Period Ending Monday • A tale of two grain belts – one very dry, one wet • Source: National Weather Service
U.S. Winter Wheat Production • 2007 - 2011 Average
Precipitation (Percent of Normal) • Weighted By U.S. Crop Production • 180-Day Period Ending Monday • 68% of HRW wheat in drought, compared to only 10% of SRW wheat
Neutral Conditions Exist • (Neither El Niño nor La Niña)
Neutral Conditions To Continue • Through Summer • Data source: Climate Prediction Center
U.S. Temperature Probability • March-April-May
U.S. Precipitation Probability • March-April-May
10 Driest May-December Periods • In Kansas-Nebraska-Oklahoma • 1895 - 2012 • Data source: National Climatic Data Center
March-April Precipitation After The 10 Driest May-December Periods • In Kansas-Nebraska-Oklahoma • Data source: National Climatic Data Center
U.S. Winter Wheat Yield • 1950 - 2012 • Data source: National Agricultural Statistics Service
U.S. Winter Wheat Yield After The 10 Driest May-December Periods • In Kansas-Nebraska-Oklahoma • Data source: National Agricultural Statistics Service
U.S. Corn Production • 2007 - 2011 Average
U.S. Soybean Production • 2007 - 2011 Average
Ideal Weather For • Highest U.S. Corn Yield
Ideal Weather For • Highest U.S. Soybean Yield
U.S. Corn Yield • 1960 - 2012 • Data source: National Agricultural Statistics Service
U.S. Corn Yield • (Departure From Trend) • 1960 - 2012 • Data source: National Agricultural Statistics Service
U.S. Corn Yield and Lagged September-March Precipitation* • 1960 - 2012 • * Precipitation in Illinois-Indiana-Iowa • Data source: National Agricultural Statistics Service
U.S. Soybean Yield and Lagged September-March Precipitation* • 1960 - 2012 • * Precipitation in Illinois-Indiana-Iowa • Data source: National Agricultural Statistics Service
Summary • A large-scale and intense drought is in progress • May-December ranked #1 driest in at least 118 years across the key winter wheat states of Kansas-Nebraska-Oklahoma • Moderate historical support for slightly dry weather and low wheat yields during the key March-April period • The drought neither increases nor decreases the odds for above-trend or below-trend U.S. corn and soybean yields in 2013 • Autumn and winter weather hold no predictive value for future U.S. corn and soybean yields
U.S. Earthquakes • Do you live in the Midwest or Mississippi Delta? • Have you ever felt an earthquake?
San Francisco Earthquake • Magnitude 7.9 on April 18, 1906
U.S. Earthquake Risk • The risk of a major earthquake in the central U.S. “is as high as for places in California” – United States Geological Survey, 2007 • Source: United States Geological Survey
Two Seismic Zones In • The Corn Belt and Delta
Halloween Earthquake • Near Cairo, Illinois • Magnitude 6.8 on October 31, 1895 • Source: United States Geological Survey
New Madrid Earthquake Sequence • December 1811 – February 1812 • 4 earthquakes of Magnitude 7.8 – 8.1 • 8 earthquakes of at least Magnitude 7.0 (not aftershocks) • “…weeks to months…” of disruption would affect agriculture and its transportation infrastructure if a sequence recurred today – USGS 2009
South America • Grains and Oilseeds
Argentina Precipitation • Last 90 Days (Ending Monday)
Argentina Precipitation • Last 30 Days (Ending Monday)
Summary • Argentina is drying and its corn and soybeans need rain to return • Key corn and soybean areas of Center-West / Southeast Brazil and Bahia have been drier than average throughout most of its growing season
