                         nubes convectivas ({"}clusters{"}) basado en un umbral de 
                         temperatura (235 {K);} el calculo de los par{\'a}metros

                         principales resultados son: (1) El tiempo de vida medio de los SCM 
                         es de 4 horas mientras que el tamaņo m{\'a}ximo medio de los 
                         mismos es de 14000 km2. (2) La iniciaci{\'o}n de los SCM coincide 
                         con el horario de la m{\'a}xima insolaci{\'o}n, lo que viene 
                         acompaņado por un proceso de fuerte {expansi{\'o}n;} (3) la mayor

                         (Forecasting and Tracking of Active Cloud Clusters) is an 
                         automated method to document physical characteristic of mesoscale 
                         convective systems (hereafter MCSs) during its whole life cycle 
                         using the thermal channel (10.8 {\μm)} of geostationary 
                         satellites. The main features of this software are the following: 
                         the cloud clusters detection method based on a threshold 
                         temperature (235 {K);} the evaluation of morphological and 
                         radiative parameters of each MCSs detected in the previous {step;} 
                         the tracking technique based on overlapping areas between 
                         successive {images;} the life cycle building {(?families?);} and 
                         the virtual image generation. This methodology has been applied to 
                         a data set covering SALLJET project period over Del Plata basin. 
                         The main results are: (1) the mean lifetime is around 4 hours, 
                         while the maximum mean size is 14000 km2. (2) The spontaneous 
                         generation of the MCS is coincident with maximum insolation time, 
                         this process is accompanied by a strong area {expansion;} (3) the 
                         maximum convective activity occurs during the night.",
