随着渤海油气的开发和冰区航行的发展,石油公司和航运部门需要了解详细的渤海流冰的速度和方向。为此,国家海洋环境监测中心海冰室和国家海洋局青岛海洋预报台海冰组经过数年的合作建立了渤海流冰数值预报系统。该系统包括海冰场处理,风场处理,流场预报,流冰场预报和预报产品应用等五大部份。海冰场处理是对接收到的卫星冰图进行数学化处理,得到适用于计算的海冰厚度、密集度等初始场资料。风场处理是把预报出的气压场换算成渤海海面风场。利用流场预报模式对渤海流场进行数值预报。流冰预报场是
With the development of oil and gas in the Bohai Sea and the development of navigation in the ice region, oil companies and shipping departments need to know the detailed speed and direction of ice flow in the Bohai Sea. To this end, the National Marine Environmental Monitoring Center ice chamber and the State Oceanic Administration Qingdao Ocean Forecast Taiwan sea ice group after several years of cooperation to establish a numerical simulation system of ice flow in the Bohai Sea. The system includes five parts: sea ice field treatment, wind field treatment, flow field forecasting, ice rink forecasting and forecasting product application. The sea ice crust processing is to process the received satellite ice map to obtain the initial field data that is suitable for calculating the thickness and density of the sea ice. Wind field treatment is to predict the pressure field converted into the sea of Bohai Sea wind farm. The numerical predictions of the Bohai Sea flow field are made using the flow field prediction model. Ice forecast field is
