Variability in the General Circulation and Climate Processeson Seasonal and Interannual Time Scales

这是一个多方面的项目，旨在诊断和了解造成大气环流和气候年际波动的过程的行为。调查分为三个部分。第一部分试图更好地确定在目前的赠款下发现的对流层温度年际变化的机制。第二个目的是探讨全球综合大气角动量年际变化的机制，重点是1982-1983年的厄尔尼诺事件。该提案的第三项任务是诊断非绝热供暖不同组成部分的年内波动及其在产生可用势能方面的作用。拟议的调查非常重要，因为打算对大型模型输出数据和观测数据集进行比较，将有助于找出全球观测网络和现有全球气候监测公式中的具体缺陷，这应受到科学研究界的高度重视。同样重要的是，这一建议将提供对大气能量预算和角动量的更好理解，这可能对理解气候过程具有重大影响。

This is a multifaceted program aimed at diagnosing and understanding the behavior of processes responsible for interannual fluctuations in the general circulation and climate. There are three parts to the investigation. The first part attempts to make better identification of the mechanisms responsible for the interannual variations in tropospheric temperature discovered under the current grant. The second intention is to explore the mechanisms responsible for interannual variations in globally-integrated atmospheric angular momentum with focus on the 1982-1983 El Nino event. The third task of the proposal is to diagnose the intra-annual fluctuations in the different components of diabatic heating and their role in generating available potential energy. The proposed investigation is very important because the intended comparisons between the large, model output and observed data sets will help to isolate the specific deficiencies in the global observing network and the existing GCM formulations, which should receive the highest priority by the scientific research community. Equally important, this proposal will provide better understanding of the atmospheric energy budget and angular momentum which could have significant implications for understanding the climate processes.
