摘要
本文建立了一个34层包括牛顿冷却、Rayleigh摩擦和非绝热加热线性原始方程谱模式。用此模式对地形强迫为下边界条件进行时间积分。结果表明,此模式计算稳定,有较好的精度及计算时间节省的特点模式的积分结果还表明,此模式对球面大气准定常行星波的形成和传播有较好的描写能力。
In this paper, a linearized spectral model of the primitive equation with 34-level including Newtwonian cooling, rayleigh friction and diabatic heating was established.The time integrating of the model was carried out by taking the topography forcing as the lower boundary condition. The integrating results show that the model is stable and has the advantages of time saving and high precision in the calculation. It also shows that the model has strong describing ability on the formation and transportation of stationary planet waves.
