| 摘 要： | 本文分析了中国科学院大气物理研究所大气环流模式(IAP GCM)模式大气波谱结构(沿纬圈的谐波波谱和时域上的频率谱)及其在厄尔尼诺年的异常。结果表明,超长波是低纬波动的主要空间形式,准40天振荡在一定地理区域内显著存在,并与观测结果有一定联系,它们在厄尔尼诺年均发生明显异常。本工作对鉴定GCM性能及开发GCM的研究领域可能是一种有益的尝试。

| Abstract: | Analysis is performed of the spectral structure of the atmosphericwaves (i. e.,harmonic spectrum along the latitudinal circle and frequency spec-trum in the time domain)simulated by the general circulation model (GCM),pro-posed by the Institute of Atmospheric Physics (IAP),Academia Sinica, and theiranomalies in an El Nino year. Results show that ultra-long waves represent theprincipal form of low-latitude waves, characterized remarkably by quasi-40-day oscillations in a given geographic locality and somewhat related to the obser-vations and significant anomalies are experienced in an E1 Nino year. Perhaps thepresent study is a useful attempt at the assessment of the GCM'S performancesand the expansion of its research domain. |
