Fig. 2From: Idealized simulations of tropical cyclones with thermodynamic conditions under reanalysis and CMIP5 scenariosa The spatially and temporally averaged vertical profiles of Tatm (solid lines) in the upper troposphere and \({r}_{v}\) (dashed lines) for the following reanalysis data: NCEP/NCAR R-1 (green), ERA20C (blue), and CIRES20 (red) and the vertical profile of Jordan (1958) sounding (purple). P is pre-stage from 1921 to 1950, M is mid-stage from 1951 to 1981, and L is later-stage from 1981 to 2010. b The changes of Tatm and c \({r}_{v}\) were calculated as differences between pre-stage and other stages of reanalysis experiments, but differences between mid-stage and later-stage were calculated for NCEP/NCAR R-1Back to article page
