APPLICATION OF PARALLEL PROCESSING - A CASE STUDY ON WEATHER PREDICTION Nur Shafiqah Ahmad Bzayauddin #1, Mohamed Faidz Mohamed Said #2 # Faculty of Computer and Mathematical Sciences, Universiti Teknologi MARA 70300 Seremban, Negeri Sembilan, MALAYSIA 1 shafiqahbzayauddin@gmail.com 2 faidzms@ieee.org Abstract— In this paper, we study about application of parallel processing on weather prediction. In particular, the predicted weather data about the future air state is essential and vital for all different areas of ecological modelling. Besides, the right choices to counteract harms and spare lives could be taken depending on a solid meteorological forecast process. Parallel processing takes a critical part in numerical climate and sea estimating models like Weather Research and Forecasting Model (WRF), Princeton Ocean Model (POM) and Regional Ocean Modelling System (ROMS). Numerical weather prediction is the most proficient intended to lessen the impact of startling climate occasions. Advances of high-performance computing have been enhanced much with the expanding of prediction accuracy and the time-critical requirement. There are existing operational centers like European Centre of Medium Range Weather Forecasting, UK (ECMWF) and National Centre for Environmental Prediction, USA (NCEP) which are exploring relationship between parallel processing and numerical weather prediction. This paper attempts to investigate and analyse the computational time required for the complex numerical simulations of climate and sea models using parallel processing.
