                         in S{\~a}o Jos{\'e} dos Campos made it possible to observe the 
                         characteristics of convective activity in the Para{\'{\i}}ba 
                         Valley region. The convective activity not associated with the 
                         synoptic scale systems in this region during the summer months is 
                         observed mostly in the afternoon hours from 17:00Z to 24:00Z. The 
                         convective cell arrangement in the region shows an 
                         along-the-valley pattern, thereby indicating that the regional 
                         topography plays an important role. An area of maximum occurrence 
                         of convection is situated between Pindamonhangaba (PND) and 
                         Guaratinguet{\'a} (GUA) cities preferentially during the period 
                         from 20:00Z to 22:59Z. The maximum occurrence observed in this 
                         area reaches 26% of the days. The radar echo maxima occur in the 
                         range of 14,6 to 19,5 dBz, corresponding to ~2 mm/h and in the 
                         range of 24,6 to 29,5 dBz corresponding to ~10 mm/h rainfall. A 
                         second area of maximum convective occurrence is situated near the 
                         Cruzeiro´s city (CRZ). The activities in these two areas are 
                         negatively correlated (-0,71) in terms of their maximum echo 
                         intensity. Weakening of convective activity in the CRZ region in 
                         the period from 20:00Z to 22:00Z is quite possibly due to the 
                         subsidence caused by strong convection in the area between PND and 
                         GUA.",
