    Analyzed parameters : name of the issuing centre (FMEE), date, storm identifier (name), position, current motion and intensity of the system, envelope of the cloud area associated with presence of frequent CB, CB tops maximum height (in flight level), the boundary of surface winds of at least gale force. Forecast parameters : positions and intensities (10-min average maximum winds) of the system at 06, 12, 18 and 24 hours lead times. Frequency and updating : graphical product issued as soon as a tropical system generating surface winds of at least gale force is present within the area of responsibility and disseminated every 6 hours, normally within one hour after the synoptic time (00, 06, 12, 18 utc). Production tool : Synergie.

    Lagrangian trajectories of three particles launched at 500, 1500 and 3000m levels. Particles are then subjected to wind advection. The wind field is provided by the ARPEGE meteorological model. The trajectories cover a global area, from 0h to 84h, starting from the time of release. The time step is 6 hours. Outputs are in png format. Data access is restricted to institutional authorities.

  • Recorded tracings of high-frequency (HF) radio pulses reflected in the ionosphere. This ionograms are produced by an ionosonde at Yamagawa, Japan. The ionosonde sweeps HF radio pulses from 1MHz to 30MHz, basically every 15 minutes. The transmitted radio pulses travel more slowly within the ionosphere, depending on the ionospheric plasma density. The apparent height, that is, virtual height of the reflection point is recorded for each frequency of the transmitted HF radio wave. When the frequencies become higher than the maximum plasma frequency of the ionospheric layer, the radio wave pass through the layer and be lost in space. The profile of the ionospheric plasma density can be obtained from this data.
