Abstract

Cb-TRAM is a fully automated tracking and nowcasting algorithm. Intense convective cells are detected, tracked and discriminated with respect to onset, rapid development, and mature phase. In addition, short range forecasts are provided. The detection is based on Meteosat SEVIRI (Spinning Enhanced Visible and Infra-Red Imager) data from the broad band high resolution visible, infra-red 6.2 µm (water vapour), and the infra-red 10.8 and 12.0 µm channels. Areas of convection initiation, of rapid vertical development, and mature thunderstorm cells (cumulonimbus Cb) are identified. The tracking is based on geographical overlap between current detections and first guess patterns of cells detected in preceding time steps. The first guess patterns are obtained with the aid of an image matching algorithm providing complete fields of approximate differential cloud motion. Based on this so-called pyramid matcher also nowcasts of motion and development of detected areas are provided. Examples of application are presented for thunderstorm detection and tracks over the Mediterranean
