Summary of regions and time lags where the absolute correlation between seasonal solar radiation and SST/GPH850 is larger than 0.3 with p-values less than 0.05.

| SST2 | −5°N~5°N, 180°E~240°E[−5, 0] negative correlation | |||
| GPH850.1 | 60°N~70°N, 100°E~140°E[−3,−1] positive correlation | −10°N~10°N, 60°E~85°E[−4, 0] negative correlation | ||
| GPH850.2 | 0°N~25°N, 50°E~100°E[−6, 0] negative correlation | 10°N~30°N, 140°E~200°E[−6,−3] positive correlation | ||
1 and 2 in SST and GPH850 are the index.
The temporal lags between the study site solar radiation and SST/GPH850 are presented in the square brackets. Negative values indicate the months in which SST/GPH850 is ahead of the study site solar radiation time series. The blank cells indicate that no SST/GPH850 region with spatially coherent and temporally persistent correlation to seasonal study site solar radiation was identified.
