Fig. 6: Composite soil moisture anomalies and the ratios of soil moisture anomalies in the observation.
From: Amplified impacts of multi-year La Niñas on soil moisture compared to single-year La Niñas
a The DJF of the observed SY La Niña, b first DJF (DJF0) and c second DJF (DJF+1) of the observed MY La Niña during 1948–2020. d, e The ratios of soil moisture anomalies, calculated by the first DJF and second DJF of MY La Niña divided by the SY La Niña. Yellow and green contours in (e) are negative and positive soil moisture anomalies in SY La Niña as illustrated in (a). Hatchings in (a–c) indicate areas where the values exceed the 95% confidence interval determined using a two-tailed Student’s t-test.
