Meteorological Applications, Volume 33, Issue 2, March/April 2026.This study assesses prediction quality of regionally refined (downscaled) calibrated multimodel predictions for Ceará State in Brazil. Downscaled predictions maintained similar performance levels to those obtained at the coarser spatial resolution of the used global models, reassuring the adequacy of the cascading procedure used to generate predictions
