Correlation coefficients calculated when excluding IPSL-CM5A-LR, the model with anomalous surface flux, are in parentheses. The correlations that are significant with P value smaller than 0.01 are in bold. FA (0), atmospheric cross-equatorial transport; ITA, interhemispheric surface air temperature asymmetry; ITTA, interhemispheric tropical surface air temperature asymmetry; PrI, precipitation asymmetry index.
