U2U Decision Support Tools - Climate Patterns Viewer
Welcome to Climate Patterns Viewer – connecting global climate conditions to local climate impacts.
This product provides a historical look at how the El Niño Southern Oscillation (ENSO) and Arctic Oscillation (AO)
can influence local climate conditions and corn yield across the Corn Belt. You can use these simple maps and charts
to show when and where specific phases of ENSO or AO have influenced:
average monthly temperatures and precipitation,
deviations of temperature and precipitation from 1981-2010 climate normals, and
average detrended corn yields (adjusted to 2010 technology) and deviations from average
This tool is not intended to be a forecast. Rather, this tool uses historical data (1981-2010) to highlight locations where ENSO and AO can potentially impact climate conditions over the course of the year, which can help you make more informed farm management decisions.
