IIIviii Tropical cyclones tracks
Tropical cyclones tracks are provided in BUFR code, free of information charge. They are composed of 52 trajectories corresponding to:
 the 50 perturbed forecasts from ENS (Ensemble Member numbers 1 to 50 in BUFR)
 the control forecast from ENS (Ensemble Member number 51 in BUFR)
 the HRES forecast (Ensemble Member number 52 in BUFR)
The tropical cyclone trajectories are computed independently for each ensemble member; a given tropical cyclone may dissipate at different times in different members so the number of members predicting a given tropical cyclone may vary through the forecast.
Observed (existing cyclones) and genesis (created by the forecast).
