| 摘 要： | 本文介绍一两层准地转的球面长波谱模式(LWM)。它包括非绝热加热、地表摩擦和山脉分布。试验表明,由于引进瞬变涡旋输送特征参数化,LWM较低阶谱模式(LOM)有显著改进。它除具有LOM经济简明的优点外,还更合理地描述大气的能量循环和角动量平衡,更准确地模拟纬向西风和定常波。因而适于理论研究和数值模拟。

| Abstract: | A two-level,quasi-geos trophic long-wave model based on spherical coordinates was introduced.Its explicit part belongs to a low-order model.However,it includes not only diabatic heating,Ekman friction and mountain distribution,but also parameterized forcing effects of transfer properties of transient eddies,Experiment results showed that,due to the introduction of the parameterization of transfer properties of transient eddies,remarkable improvements in behaviours of low-order models had been obtained.In addition to its economization in calculation and conciseness in research as in a low-order model,the long-wave model was shown to describe the energetics and angular momentum balance of the atmosphere much more reasonably,and to present the features of zonal mean westerlies and stationary waves much more correctly than the corresponding low-order model.This kind of long-wave model was therefore regarded as suitable for theoretical researches and numerical modeling of some aspects of the general circulation of the atmosphere. |
