Extended Data Fig. 3: The Lagrangian decomposition of the temperature variability for the ERA-I reanalysis data.

From: Changes in Northern Hemisphere temperature variability shaped by regional warming patterns

Extended Data Fig. 3

The mean intensities of the 850 hPa (a) cold \((\left| {T^\prime } \right| = T_c)\) and (b) warm \((\left| {T^\prime } \right| = T_w)\) anomalies (K), produced from the temperature tracking statistics, and (c) the approximate temperature skewness, \(S \approx \frac{{T_w - T_c}}{{\frac{1}{2}(T_w + T_c)}}\), during NH winter (DJF). Panels (d)-(f) show the same but for the summer period (JJA). These results can be compared with the same quantities from the historical CMIP5 simulations (panels b,f of Fig. 2, and panels a,b,e,f of Fig. 3 in the manuscript).
