Recently, when parsing ECMWF BUFR tracking data, I noticed that under the same initialization time (run time), there are multiple cyclone names/identifiers listed, such as 30W, 71W, 72W, etc., with very similar latitude and longitude positions. Furthermore, in some of the BUFR messages, the coordinate information corresponding to 008005==1 is missing.
I would like to ask the experts here: What is the cause of this phenomenon? Additionally, if I want to reconstruct and organize the entire life cycle of a specific cyclone, which identifier should I use, or what is the correct data processing strategy?
Currently, I am attempting to merge all data under a single identifier name, but this results in severe track jumping (sudden displacements). The results look incorrect in both the deterministic forecasts and the ensemble prediction systems (EPS). How should this issue be properly resolved?
Below are the track plots obtained when using a single identifier name for an individual cyclone, as well as the member track plots under that same identifier.
