摘要
利用中尺度大气数值模式MM5的最新版本MM5V3和一个三维的河口、海岸和海洋环流模式ECOM-si实现了一个MM5V3/ECOM-si的中尺度海-气耦合数值模式.耦合模式中大气模式底边界由海洋模式预报的SST强迫,海洋模式的上边界由大气模式预报的海面风应力、感热通量、潜热通量、净长波辐射通量和吸收的太阳短波辐射通量强迫,两个模式在相应的时步上互相交换信息并同时运行.为了验证耦合模式的效果,文中利用耦合前后的模式分别对黄东海区域1995年3月的一个入海气旋的个例进行了36h的模拟试验,并对前后模拟的结果进行了初步的分析.
As the latest version of MM5, a mesoscale atmospheric model MM5V3 was used to complete an airsea coupling numerical model with ECOMsi, a 3D coastal ocean circulation model. The lowerlayer boundary of atmospheric model was forced by the SST predicted by the sea model, and the upperlayer boundary of the oceanic model was forced by the sea surface wind, sensible heat flux, latent heat flux as well as long wave radiation and short wave radiation. The atmospheric model and oceamic model can run at the same time and exchange information at the exact time step. To test the coupling effect, a passing cyclone evolving over the Yellow and East China Seas in 1995 was chosen as the case for a 36hour numerical simulation and simulation results were also analyzed.
