| 摘 要： | 为了模拟大尺度动力过程并改进数值预报,开展了一个原始方程的半球数值模式的研究。 模式的主要特点是:将热力学方程进行改写,整个差分格式保持总能量守恒,但气压梯度项和静力关系的差分格式可以不受任何限制。模式包括地形、摩擦、水平扩散、降水、蒸发和各种非绝热等物理作用。幅射作用直接由导出的微分表达式计算;地面温度由地面热量平衡方程解出而不需要迭代计算。 最后给出这一模式的一次48小时预报个例的试验结果。

| Abstract: | In order to simulate the large-scale dynamic process and improve the numerical weather prediction, a primitive equation hemispherical model is developed. Characteristic features of the model are as follows: The thermodynamic equation is written in the form as equation(6).The difference schmes of the model preserve total energy but the difference schemes of the pressure gradient and hydrostatic
relation have not any constraint. The physical factors of orography, friction, horizontal diffusion, large-scale precipitation, evaporation and various non-adiabatic heating are included. The radiational heating and cooling is designed to evaluate directly from the differential expression(21) and(22),and the ground temperature is calculated from the solution(24) without iteration. The model was tested to give an example of 48 hours predition. |
