Fig. 5: Observed and simulated changes in precipitation.
From: Simulated Antarctic sea ice expansion reconciles climate model with observation
Linear trends of annual mean precipitation over 1979–2014 (color shading in mm/day/decade) from (a) the average of CMAP, GPCP v2.3 and NOAA’s Precipitation Reconstruction (PREC) data, (b) HIST_ASI+ and (c) HIST_ASI- ensemble means as well as (d) the difference between the two (HIST_ASI+ minus HIST_ASI-), superposed by annual mean precipitation climatology over 1979–2014 for HIST_ASI- ensemble mean (contour in mm/day with an interval of 2 mm/day). The stipples refer to the regions where trends are statistically significant based on Student’s t-test at 95% confidence level.
