AbstractModel precipitation can be produced explicitly or through convective parameterization schemes. Different types of precipitation produce distinct vertical profiles of latent heat to the atmosphere, however, to estimate the effect of these different profiles of heating it is important to know accurately the partition between convective and stratiform precipitation. Models with resolution coarser than 20 km are able to reproduce the cumulus convection with some skill through parameterization schemes. On the other hand, models with grid-size resolution smaller than 1 km should solve the convection explicitly. Within the range of these two resolutions hybrid solutions are suggested, with cumulus convection acting together with the explicit form of representation. In the present work, the Eta model was used to simulate a precipitation event associated with the South Atlantic Convergence Zone (SACZ). This type of system exhibits a large band of stratiform cloudiness with embedded convective cells. The Eta Model uses the Kain-Fritsch cumulus parameterization scheme. Cloud microphysics was treated by Ferrier scheme. The convective scheme has a parameter that controls the fraction of condensate that goes into rain and snow in each layer. A change is proposed to the parameter to include resolution dependence. The convective scheme converts less condensed water into precipitation, part of the condensed water is made available to cloud microphysics scheme and another part evaporates. In grid resolution higher than 1 km, convective scheme still acts in removing convective instability and all precipitation is produced by cloud microphysics. Simulations with different horizontal resolutions, 20, 10 and 5 km, have been carried out up to 5-day integrations which is the average duration of SACZ events. The changes produced two major impacts: the position of maximum precipitation area was better simulated and the amount of total precipitation became closer to the observations. The simulations showed that the increase of horizontal resolution changed the distribution of stratiform and convective precipitation.
