The China Sea Weather Forecast System


The East China/Yellow/Bohai Seas weather forecast and hindcast system was developed using the Weather Research and Forecasting (WRF) Model. The model is configured with regional and local domains with horizontal resolutions of 30 km and 10 km, respectively. The regional domain covers the entire East China/Yellow/Bohai Seas and the East/Japan Sea. The local domain covers the Yellow and Bohai Sea.

The forecast is made every 3 days with snapshot of the distribution of surface wind speed, air pressure, humidity, and air temperature over a time interval of 3 hours. The temporal variation of these meteorological variables over the forecast period can be viewed by clicking “animation”. The hindcast is also made by data assimilation approach for the same period after the surface buoy and satellite-derived SST data are received. The display structure of the hindcast model results are the same as those shown in the forecast model results.

The images and animations shown in “3-D Forecast” are plotted with a reduced resolution to make them viewable on the web, particular for the local domain in which the model is run with a horizontal resolution of 10 km.
