%3 TRANSIENT CONVECTION....pdf
%X A two-layer, nonlinear, equatoria, B-plane model, in p-coordinates 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/Bolívia region. The boundary conditions used are meridional velocity zero at 60ºN and 60ºS, 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 10ºS. 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.
