                         study aims to analyze the climatological classification of 
                         precipitating clouds in Northeast Brazil using radar on board the 
                         satellite Tropical Rainfall Measuring Mission (TRMM). This 
                         satellite while in orbit, had the scope to measure the amount of 
                         rainfall in tropical regions. One main instrument aboard this 
                         satellite is an active radar scanning electron which aims to 
                         detect the three-dimensional structure of clouds. Thus, for this 
                         study was analyzed a series of 15 years of TRMM satellite data 
                         (period 1998-2012), in order to identify what types of clouds 
                         produce precipitation estimated by Precipitation Radar (PR) and 
                         how often these clouds occur. From the results of this work was 
                         possible to estimate the average frequency values concerning each 
                         type of cloud present in weather systems that influence the 
                         Northeast region of Brazil. In general, the stratiform clouds and 
                         shallow convective clouds (hot clouds) are the most frequent in 
                         the region, but the associated rainfall is not as impactful as 
                         precipitation caused by deep convective clouds. Also appears that 
                         over the coastal areas of Brazil and adjacent Northeast ocean 
                         there is a strong signal of shallow convective clouds that 
                         modulate rainfall in these areas. Thus, the main objective of this 
                         dissertation is to contribute to a better understanding of the 
                         patterns of cloud types associated with precipitation of 
                         northeastern Brazil, building a climatological analysis from the 
                         classification of clouds.",
