| Resumo | This study investigated the behavior of the variability of precipitation in South America under different surface forcing and vertical diffusion, based on the assumption that the surface is an important reservoir of energy. It was used the Atmospheric General Circulation Model of the Center for Weather Forecasting and Climate Studies (AGCM-CPTEC/INPE) at the spectral resolution TQ0213L042 (~ 60 km and 42 vertical layers). It was implemented the SiB2 and IBIS-2.6 surface schemes and boundary layer parameterization of Holtslag Boville modified with different setting options of closure for the calculation of diffusion coefficient. It was performed for each day during the period of January 1, 2003 to January 10, 2003, several simulations (experiments) with forecasting up to 10 days and different physical combinations of surface and planetary boundary layer parameterizations. The initial conditions used were the analysis of the NCEP in the spectral resolution TQ0254L064 degraded to model resolution and the sea surface temperature in the resolution of 1 degree, interpolated to model grid. The analyses are based on the set of simulations produced by physical experiments, where each member of this group is compared to TRMM3b42 precipitation data, analysis of the NCEP and the average of the members. The modification of surface parameterization schemes showed results with significant dispersion of precipitation as expected, due to differences in the parameterization formulations. In relation to the closure options of the boundary layer it was not seen so much dispersion of precipitation with respect to the control experiment. To explain the dispersion of precipitation it was applied the wavelet analyses on the time series of net of energy on the surface obtained from the energy balance variables of the experiments. It was removed from the average of the diurnal cycle to verify the dispersion of the sign of the surface net of energy (ground, canopy). This method proved to be efficient because, it has shown qualitatively how the energy stored in surface dissipates for periods longer than one day. It also shows how the energy stored during the diurnal cycle may influence the maintenance of precipitation for a period of time longer. This behavior can be defined as a signal memory of the surface balance energy of the diurnal cycle. With the wavelet analyses of the surface balance energy and the dispersion of precipitation of the members in relation to control and TRMM3B42 it was concluded that although more simplified the SSiB scheme represents well the precipitation and the surface balance energy and presents a clear signal for periods of 1 to 3 days corresponding to the areas where precipitation occurs. The SiB2 scheme has the same pattern, but overestimates the precipitation in the Amazon region. The IBIS scheme maintains the standard underestimating the precipitation in the central region of Brazil. |
