Figure 4

The SWR and THF patterns preceding an inter-annual GMST anomaly. (a–d) Regression patterns at different lags. Net shortwave radiation leading GMST by 2 years (a), and 1 year (b). Turbulent flux leading GMST by 2 years (c), and 1 years (d). All regression patterns are in (W m⁻² K⁻¹). In (a,d) colour intervals are 4 W m⁻² K⁻¹, but the first and last intervals are −80 to −26 and 26 to 80 W m⁻² K⁻¹. Only significant values using 95% confidence intervals are shown.
