Figure 7: 1980–2016 standardized SAM Index, Equatorial SOI, West Antarctic melt index and melt extent anomalies.
From: January 2016 extensive summer melt in West Antarctica favoured by strong El Niño
Years are rank-ordered from lowest to highest melt extent. For each year (x axis), the plot displays (in the following order) the melt index (light blue), the melt extent (dark blue), the SAM Index (orange), and the equatorial SOI (red). The plot is adapted from ref. 22.
