Investigating the Influence of Anthropogenic Forcing on Observed Mean and Extreme Sea Level Pressure Trends over the Mediterranean Region

Figure 3

Results from consistency of spatially averaged changes. Blue bars: seasonal uncentred regression coefficients ( 𝑦 axes) of observed SLP changes onto the changes in response to GS forcing derived from 17 climate change projections ( 𝑥 axes) based on the SRES A1B scenario. Red bars: regression coefficient of observed SLP changes onto the simulated GS signal estimated from ensemble mean of 17 ANT simulations (conducted with 9 models). Whiskers show the 90% uncertainty ranges of regression coefficients derived from model-based estimates of natural (internal) variability (206 nonoverlapping 30-year segments derived from 6,200-year control runs). The solid lines mark regression indices equal to unity indicating consistency with GS forcing.
