Fig. 4

Snapshot of the subgrid tendency of qT at 5.7 km in kg kg−1 s−1 showing ac the true tendency and df the error in the prediction from RF-tend. Results are shown for a, d subgrid tendencies calculated and predicted at x4, b, e coarse graining of the subgrid tendencies calculated and predicted at x4 to x32 grid spacing (x4 → x32), and c, f subgrid tendencies calculated and predicted at x32. Inset text gives for the snapshot shown ac the standard deviation of the true tendencies and df the root mean square error.
