Correlation coefficients between October soil moisture at various depths, IPFPI, and winter wheat climatic yield. (a), (c), and (e) Correlation coefficients between 10-, 20-, and 30-cm soil moisture during October in China and IPFPI for 1982−2010, respectively; and (b), (d), and (f) correlation coefficients between 10-, 20-, and 30-cm soil moisture during October in China for 1982−2010 and winter wheat climatic yield in the NCP during the following year (1983−2011), respectively. Red dots indicate positive correlations and black dots indicate negative correlations. Open circles indicate no statistically significant correlation, and solid circles indicate a statistically significant correlation at the 90% level, (maps produced by NCL Version 6.6.2, http://dx.doi.org/10.5065/D6WD3XH5)46.
