Figure 4: Relationship between observed and forecasted T2m (°C) by RegCM_CFSv2 for all stations, all target months, and all lead times for experiments of (a) the control run—CTL, (b) the bias correction by model climatology—BAS, and (c) the successive adjustment of BAS with model bias at one month lead time of the previous run—SUC. The solid red line is the linear regression of the forecasted versus observed T2m. The perfect regression line is presented by the black line.
