Left to right: prediction of ERA5, CorrDiff and Target for different fields, followed by their averaged cross section from 21 lines parallel to the thin dashed line in the contour figures. Top to bottom: 2-m temperature (arrows are wind vectors), along front wind (arrows are along-front component of the wind vector) and across front wind (arrows are across-front component of the wind vector). At the right column, the cross sections of the target (WRF, black line), ERA5 (red line) and the UNet (blue line) are compared with the mean of a 32 member ensemble predictions from CorrDiff (orange line) where the shading shows ± one standard deviation.
