New Tropical Cyclone Track products from ECMWF on the GTS

 

ECMWF started providing new Products on the GTS.  Tropical Cyclone Track products produced by the Deterministic Forecast and the EPS (Ensemble Prediction System) coded in BUFR are made available from 00 and 12 UTC basetime.  The tracks delineate the positions of tropical cyclones from the analysis to 120 hours into the forecast in 12 hourly timesteps.  The forecasts run twice a day but products will only be generated and inserted onto the GTS if there are some observed positions of tropical cyclones or Tropical Cyclone Tracks have been detected in the forecast.

The products are inserted onto the GTS via Offenbach and Exeter and have the following bulletin headers:
TT . .. JS - BUFR, Surface/Sea Level
AA .. . XX - other surface data/global area (not defined)
ii ... 01-19 - sequence number of tropical cyclone track bulletin
GGGG .. ECMF/ECEP - deterministic forecast/ensemble prediction system
YYGGgg YY0000/YY1200

A detailed description of bulletin headers can be found on the following web page.
The products are also made available in graphical form on the ECMWF web.
