| Resumo | GCM are generally initialized about a few months before the forecast period to allow some spin-up time for the soil moisture. During this initialization period, observed SST are used over the ocean. While in the GCM, the integration is mostly controlled by the lower boundary, in the limited area models, the climate state is related to the lateral boundaries, which are provided by the GCM. In longer spin-up time, model errors are also allowed to grow larger before saturation is reached. In this work an evaluation of seasonal forecasts using the Eta Model driven by CPTEC GCM, which was initialized at different spin-up time, is shown. The Eta Model domain covers most of South America, and was configured with 40 km and 38 layers. The CPTEC GCM run at T62L28 resolution. The soil moisture was initialized from monthly climatology, whereas sea surface temperature was taken from observed weekly mean. The GCM used Kuo convection scheme whereas the Eta Model used the Betts-Miller scheme. The model produced 3-month forecasts using persisted sea surface temperature anomaly. Two periods of initialization were taken: 2.5 and 0.5 months before the start of the forecast period. Results are shown for December-January-February (DJF) season of 3 different years: 1997, 1998 and 1999, which comprise one El Niño and one La Niña event. DJF is the rainy season for most part of the South America continent. Precipitation forecasts from the CPTEC GCM are compared against surface observations in four major regions: Amazon region, Center-South, Northeast Brazil and the San Francisco river basin. Daily mean precipitation values of the two modes of run are very close in the Amazon and Center-South region, with no clear forecast bias. In the smaller regions, Northeast Brazil and the S. Francisco Basin, either 2.5- or 0.5-month spin-up time runs, show some difference, however, both forecasts similarly overestimated the observed precipitation. The inter-annual variability is less captured by the 2.5-month run than the 0.5-month run produced by the GCM. Precipitation forecasts from the Eta Model driven GCM forecasts from these two spin-up periods for the 3 years are also shown. Results show no clear advantage of nesting into forecasts from driver model using longer spin-up period. | |||
