Resumo | Sea surface temperature (SST) is an important variable that drives climate. Tropical Atlantic Ocean SST variability has a strong influence on the distribution of precipitation in South America, including northeastern Brazil and the southwestern Amazon region. Therefore, to seek for more accurate rainfall forecasts in those regions, our work aimed at evaluating different bias correction statistical methods to be applied onto the SST data predicted by the Brazilian Earth System Model (BESM). The reference observations were obtained from the ERA5 database. The chosen region to produce corrected SST is within the coordinates 30W-10E and 20S-0. The first method evaluated was the basic Quantile Mapping (QM), considering its wide adoption, ability to deal with higher order moments, and computationally efficiency. However, it has some drawbacks, such as requiring the same number of samples in the time series observed and the one generated by BESM to ensure an accurate distribution mapping. In addition, QM also assumes that the error correction function for the modeled and observed distributions are stationary or time invariant. To address the first limitation, we evaluate the modified QM method. Furthermore, since the stationarity assumption of QM models may be not suitable for long-term observation series, this experimental study also includes the Scaled Distribution Mapping (SDM) method. Records are daily based and span the period from November 1980 to October 2010. The bias correction procedures were individually applied to each model grid point at the study region. This investigation indicates the existence of some correlation between spatially contiguous areas and best performing methods. |
