Much of the precipitation around the globe is caused by mesoscale convective systems (MCSs). According to scientific literature, these systems are a major rainfall generating mechanisms over the Amazon Basin. Climate predictions and studies conducted until the moment show that climate change is imminent and accelerated by anthropogenic action. In this case, prevention and mitigation measures to minimize or try to avoid most of the consequences of climate change depend on knowledge of the behavior of variables such as temperature and rainfall. Thus, it is important to question how will the MCSs occur and behave over the Amazon basin in climate change scenarios? Will these systems suffer an increase, decrease or remain approximately constant? Will their intensity increase, decrease or be the same observed in the present? Currently the methods of detection and tracking the MCSs are dependent on satellite images in different bands of the electromagnetic spectrum. Although these screening methods have proven satisfactory in most cases, use them to predict the occurrence of MCSs in climate change scenario is impossible due to lack of satellite images in the future. Therefore, a method for detection MCSs using precipitation data from climate models, with high spatial and temporal resolution, is proposed and, thus, be used as a tool to answer the scientific questions mentioned above.
