Standard deviations of wintertime geopotential height in reanalysis and in FLOR. Standard deviations (m) of linearly detrended December–March 500 hPa geopotential height in NCEP/NCAR reanalysis data (a) and the 500-yr FLOR simulation (c). b, d Same as a and c but for 13-yr running mean 500 hPa geopotential height data. e Difference between reanalysis and FLOR standard deviations (a minus c). f Same as e but for 13-yr running mean data b minus d
