Temperatures and associated pressures can vary rapidly. Rainfall associated with a convective system is usually of high intensity and high cumulative.
- a convective system is characterized in particular by the presence of clouds of great vertical extension, this vertical extension varying rapidly during the revolution of the convective system.
- Convective systems are, apart from cyclones, the most dangerous meteorological structures. They generate numerous incidents and material and human accidents. They are potentially very dangerous for certain human activities: aviation, navigation, offshore activities (offshore oil exploitation, offshore wind %)

- Radar data over a certain frequency band provides information about the planet's surface (ground or sea) independently of the presence of clouds in the surveyed geographical area. This information makes it possible to calculate wind characteristics on the surface of the planet and, in the case of a maritime area, sea states.

- Radiance data and surface radar data can be taken into account, in addition to other conventional meteorological and oceanographic data such as those provided by large meteorological forecasting centers, to make a numerical forecast of a convective system, also reliably.

- the detection is performed according to wind characteristics on the surface of the geographical area calculated according to the surface radar data;
- the numerical prediction of a convective atmospheric system is based on meteorological data, oceanographic data, radiance data and / or surface radar data;
