                         is used to study the atmospheric response to a large-scale heat 
                         source varying in time. The heat source is meant to represent a 
                         convective burst whith total duration of approximately 48 hours 
                         over the Amazon/Bol{\'{\i}}via region. The boundary conditions 
                         used are meridional velocity zero at 60šN and 60šS, w=0 at the top 
                         and zero geometric velocity at the lower boundary. Sensitivity 
                         study was done which includes initial state at rest, compared with 
                         realistic initial flow. The scale of the heat source is 1500km in 
                         latitude and longitude and it is centered at 10šS. Special 
                         attention is paid to the distribution and intensity of the induced 
                         vertical motion. The model is integrated for two days and the 
                         preliminary resilts show agreement with the observed 200 mb flow. 
                         Of interest is the establishment of a trough and descending motion 
                         to the northeast of the heat source.A conjecture is thus made that 
                         the Amazon heat source and its fluctuations bear nome realtionship 
                         with the drought problem over Northeast Brazil.",
