Fig. 4

Correlation between area-averaged sea surface temperature in the SPCZ box and (top panel, a, b) melt days (nmlt) based on passive microwave satellite measurement, and (bottom panel, c, d) melt potential frequency (MPf) based on regional atmospheric model output over West Antarctica, during austral summer of (left, a, c) 1979–1998 and (right, b, d) 1999–2018. Statistically significant trends (at 90% level) are indicated by green contours. All time series were detrended prior to computing the correlations.
