Abstract: The paper presents our most current improvements to rainfall nowcasting approach with radar images. The study uses the translation model (Shiiba et al. [7]; Takasao et al. [9]) and added various features to better forecast rainfall on catchment under consideration. The forecasting time horizon is up to 3hours. The rainfall amount forecasted by translation model is then further enhanced by Neural Network to yield higher agreement with the observed weighted average rainfall for the catchment. The proposed scheme is demonstrated on a catchment in Singapore with a reasonably high performance indicator for lead times under consideration.
