Fig. 6: Seasonal vertical profiles of meridional average (15°N–45°N) vertical velocities (ω) and δDv over the Asian drylands and surroundings during 2006–2009.
From: Inverse altitude effect disputes the theoretical foundation of stable isotope paleoaltimetry

a–d Vertical velocities based on ERA5 reanalysis. e–h δDv based on TES retrievals. The dashed lines in each panel represent the longitudinal range of the area where the vertical upward movement is strongest in summer. The gray shading in each panel represents the highest elevation of the surface within a range of longitude, reflecting the complexity of the terrain in each area. MAM, March–April–May (spring); JJA, June-July-August (summer); SON, September–October–November (autumn); DJF, December–January–February (winter).
