                         Brazil has been running operationally the regional Eta model and 
                         producing 60-hour forecasts over South America on a twice-a-day 
                         basis. The forecasts have been satisfactory but some deficiency in 
                         the near surface variables has been noticed. A crude treatment of 
                         the land-surface processes based on the Bucket scheme may be 
                         responsible in part for the deficiencies. In this study another 
                         version of the model with the CAPS scheme, which contains 
                         vegetation and soil properties, is evaluated and compared for 
                         short-term forecasts. The model is run with NCEP analyses as 
                         initial conditions, and CPTEC/COLA global model forecasts as 
                         lateral boundary conditions. Model resolution is 40 km and 38 
                         layers and had the top raised to 25 mb. The new scheme has 12 
                         vegetation types and two soil layers. Short-term forecasts 
                         produced during one transition season are evaluated based on 
                         statistical scores, such as equitable threat scores of 
                         precipitation, root mean square error and forecast bias of 
                         temperature, humidity and wind. These scores are calculated for 
                         different forecast lead times, and 4 different sectors of the 
                         domain. Two case studies are also shown to illustrate the 
                         predicted fields during tropical convection in the Amazon region 
                         and a cold frontal passage in the Southeastern part of the 
                         continent. These cases are validated with surface observations.",
