| Notes: (1) Code figures 12 and 13 are intended in cases where code figures 0 and 2 may not be sufficient to indicate that significant post-processing has taken place on an intial analysis or forecast output. (2) Analysis increment represents analysis minus first guess (3) Initialized analysis increment represents initialized analysis minus analysis (4) Combination of different forecast products to produce a smooth, continuous forecast by applying weights to each individual prediction system which depend on the lead time and forecast skill (for example, seamless prediction using nowcasting to short-range and medium-range). (5) This Anomaly entry should only be used as part of a verification/score field. To properly encode an anomaly and specify the corresponding climatology, please use one of the templates designed specifically for anomalies. |
