                         Radar (TRMM-PR) data, acquired during the period 01/01/1998 
                         31/12/2000 over the tropical South America, were analysed in order 
                         to evaluate and model the diurnal cycle of rainfall near the 
                         surface. Amplitude and phase of the first harmonic revealed five 
                         main centres of high rainfall and the timing of maximum 
                         precipitation occurrence. The phase map showed the preferred path 
                         of rainfall and suggested that precipitation tends to propagate in 
                         bands which originate in the east and west extrems of the Amazon 
                         region. The easterly rain bands occur in the same area where 
                         squall lines were previously detected and mapped by others. 
                         Because there is little reference to the westerly bands in 
                         scientific literature, the results presented in this assignment 
                         are considered new findings. Those bands originate along the 
                         eastern slopes of the Andes Cordillera during the first hours of 
                         the day and propagate Northwest-Southeast oriented towards the 
                         Central Amazon for up to 18 hours. The results should be 
                         considered preliminary rather than definitive due to the low 
                         TRMM-PR sampling rate. More studies using ground radar or a longer 
                         TRMM-PR time series must be carried out in order to confirm the 
                         existence of the westerly propagating systems and shed more light 
                         on the results presented by this work.",
