Fig. 2: Simulated difference in summer circulation between 1761–1775 A.D. and 1746–1760 A.D. based on full-forcing ensemble member 001 of CESM-LME.
From: PDO influenced interdecadal summer precipitation change over East China in mid-18th century
a Surface 2 m air temperature (T2m, shading, unit: °C) and wind at 850 hPa (arrow, unit: m s-1), both are significant at 90% confidence level. b Sea level pressure (SLP, shading, unit: hPa) and wind at 850 hPa (arrow, unit: m s-1), both are significant at 90% confidence level. c Geopotential height at 850 hPa (shading, unit: geopotential meter, gpm) and wind at 850 hPa (arrow, unit: m s-1), both are significant at 90% confidence level. d Same as (c), for geopotential height and wind at 500 hPa. e Eddy geopotential height at 850 hPa (shading, unit: geopotential meter, gpm) and wind at 850 hPa (arrow, unit: m s-1), both are significant at 95% confidence level. f Same as (e), but at 500 hPa. The pink and green color contour lines represent zero eddy geopotential height during1746–1760 A.D. and 1761–1775 A.D., respectively.
