A steady, linear, two-level primitive equation model in the sigma-spherical coordinates with observed sensible heat transfer is used. The distribution of troughs and ridges at the upper level of troposphere calculated is largely in agreement with the observed. However, both the low over the Plateau and the subtropical high over the West Pacific in lower and mid troposphere... The forcing of steady perturbation in summer by diabatic heating and orographic effect, mainly of the Qinghai-Xizang Plateau is examined. A steady, linear, two-level primitive equation model in the sigma-spherical coordinates with observed sensible heat transfer is used. The distribution of troughs and ridges at the upper level of troposphere calculated is largely in agreement with the observed. However, both the low over the Plateau and the subtropical high over the West Pacific in lower and mid troposphere are too strong compared with the reality while the upper trough over the central Pacific is weak. In general, the steady perturbations are located, more or less, to the east of the observed ones at upper levels. Possible reasons of the deviation have been analysed. The effects of various basic flow, vertical distribution of heating and thermal dissipation are also investigated. It is shown that different vertical distributions of heating can result in differences of phase of perturbations. It is also pointed out that a certain thermal dissipation mechanism with increasing strength with height seems essential if the phase and structure of the steady perturbations are to be explained in a linear model. 本文应用一个球面和σ坐标原始方程线性定常模式,模拟夏季青藏高原的动力和热力强迫作用下的定常扰动.计算得到的定常扰动,在对流层上层槽脊分布和实况基本相符,但南亚高压的位置稍偏东,中太平洋高空槽较弱.在对流层中层计算的扰动振幅较实况强,特别是西太平洋副高.对偏差的可能原因进行了讨论.文中比较了不同基本气流、热源的垂直分布和热力耗散的影响,结果表明不同的热源垂直分布可以影响定常扰动的位相分布;还指出线性模式中,随高度增强的热力耗散机制对解释定常扰动的位相和结构可能是重要的. With the fundamental concept of synthetic vectros (space vectors), the ge- neral expressions for the current,voltage and flux-linkages in synthetic vectors of m-n-phase electrical machines are derived. The flux linkages expression of the stator and rotor under the joint action of the stator and rotor currents, the voltage equation and the torque equation as well as the relevant expressions for electrical power and electro-magnetic torque, all in the form of synthetic vectors, have been worked out. Through these... With the fundamental concept of synthetic vectros (space vectors), the ge- neral expressions for the current,voltage and flux-linkages in synthetic vectors of m-n-phase electrical machines are derived. The flux linkages expression of the stator and rotor under the joint action of the stator and rotor currents, the voltage equation and the torque equation as well as the relevant expressions for electrical power and electro-magnetic torque, all in the form of synthetic vectors, have been worked out. Through these expressions and equations, the steady-state and dynamic performance of m-n-phase induction machines can be investigated with ease. The expressions and equations derived can be extended to be used in the analysis of the synchronous machines with more than three phases. 利用综合矢量的基本概念，推导出ｍ、ｎ相异步电机的电流、电压、磁链综合矢量的一般表达式，定、转子电流联合作用下的定、转子磁链表达式，电压方程、转矩方程以及有关的电功率和电磁转矩表达式。利用这些关系式可以分析ｍ、ｎ相异步电机的稳态和动态运行性能。这里所推导的表达式也可以推广应用于多相同步电机。 << 更多相关文摘 相关查询
