Figure 2

Correlation coefficients between winter wheat climatic yield in the NCP during 1949−2015 and global SST during the previous October (1948−2014). Three positive-correlation areas (white boxes) and two negative-correlation areas (black boxes) were chosen to construct the IPFPI. The correlation coefficients of ±0.2, ±0.24, and ±0.31 are statistically significant at the 90%, 95%, and 99% levels, respectively (Student’s t-test), (map produced by NCL Version 6.6.2, http://dx.doi.org/10.5065/D6WD3XH5)46.
