Abstract
- We are operating the demonstration system of North-western Pacific Regional Ocean Forecasting System since January, 2011. The forecasting system is consisted of the North-western Pacific Regional Ocean Circulation Model, data acquisition and quality control system, and ocean data assimilation system. By the data assimilation system based on 3 dimensional variational method, satellite-borne sea surface temperature (SST), sea surface height (SSH), and temperature profiles are assimilated into the model once day, once a week, and once a week, respectively. After initializing the ocean model by the data assimilation, the system forecasts the ocean state over the North-western Pacific for one week. To assess its performance, we compared the forecasted temperature with the observed one taken bi-monthly by the National Fisheries Research and Development Institute of Korea (NFRDI) from February to October, 2011. The forecasted temperature well captured the mean circulation pattern over the North-western Pacific including Kuroshio and East Korea Warm Current in the East Sea, and the meso-scale activities, and the development of the thermal front southeast of the Ulleung Basin.ion and quality control system, and ocean data assimilation system.
