The results of numerical experiments, using the four-dimensional variational data assimilation system of the nonhydrostatic mesoscale model MM5, show that: the tangent linear model and adjoint model conducted by keeping the "on-off" switches the same as the basic state, can provide a good approximation of the first-order information to the NLM perturbation and a good descent direction for the minimization procedure; switching on and off at every other time step in the Kuo cumulus parameterization scheme don"t impact the convergence rate of cost function; the existence of the switches don"t impact improvement to the MM5 model rainfall prediction because that not only specific humidity ,but also wind, temperature and pressure are assimilated into the model.
非静力中尺度数值模式MM5的四维变分资料同化系统进行的数值试验结果表明:"开关"变量保持与基态一致,所构造的切向线性模式能够提供关于非线性模式扰动的一阶近似,伴随模式所计算的梯度值能够为最小化过程提供较好的下降方向;郭氏降水参数化方案中对流每隔一个积分步的交替发生并不影响目标函数最小化的收敛速度;"开关"变量的存在也不影响将风、温度、气压和比湿结合起来同化对MM5降水预报准确性的提高。

Experiment Validation of Hydrodynamics Model of Drum Level The experiment rig was designed, and the experiment equipment was also set up. The experiment results show: As the validation of sloshing period under different levels, maximum error between the results of the experiment and the model is within±10%. As the experiment validation of model under in-and-output flux, changing trends of results of the model and the experiment are consistent, though there is some error in sloshing amplitude, the numeric error is within±20%.
