Fig. 2: Composite of energy and temperature anomalies and its normalized monthly time series during summer.
From: Changes in land-atmosphere coupling increase compound drought and heatwaves over northern East Asia
Energy anomalies (\(H^\prime - H_p^\prime\)) and temperature anomalies (\(T^\prime\)) during the period (a, b) 1980–1998, (c, d) 1999–2019, and (e, f) its differences over East Asia, respectively. The dots in (e) and (f) denote the 95% confidence level based on the Student’s t test. g Monthly time series of normalized soil moisture-temperature coupling strength index (CS) (gray bars), \(H^\prime - H_p^\prime\)(orange line), and \(T^\prime\)(blue line) in summer (June-July-August). The regions contributing to the time series are marked in blue boxes [105–130°E, 45–55°N] in (a–f).
