In this study, a method of numerical weather prediction by ensemble for the South American
region is proposed. This method takes into account combinations of the numerical
predictions of various models, assigning greater weight to models that exhibit the best
performance. Nine operational numerical models were used to perform this study. The main
objective of the study is to obtain a weather forecasting product (short-to-medium range) that
combines what is best in each of the nine models used in the study, thus producing more …
