Centre county Pennsylvania, USA | 61 year trend projected 2016 corn yield is 164 ish. Projected yield standard deviation is 10 ish. US corn belt June through July climate temperature anomaly will determine 2016 corn yield departure from trend projected 2016 corn yield. Positive climate temperature anomaly during that critical June through July growing period will put 2016 final US corn yield below projected 2016 tend yield. Negative climate temperature anomaly during that period will put 2016 final US corn yield above projected 2016 trend yield.
100 years of NOAA reported climate data for US corn belt shows that June through July rainfall anomaly is inversely correlated with temperature anomaly in the US corn belt geographic area (Positive temperature anomaly produces negative rainfall anomaly). Corn yield model for US corn belt shows temperature anomaly alone explains more that 85 percent (Rsquared = 0.858) of corn yield deviation from trend yield. |
