需要对大气动量和能量输送进行诊断，以调查气候模式中环流偏差的来源，并了解大气对自然和人为强迫的反应。大气动力学中的模型偏差是增加区域气候、降水和极端事件预测不确定性的因素之一。在这里，我们定义了在耦合模式比较项目第六阶段(CMIP6)的背景下，诊断大气环流和时间尺度上的可变性以及评估动力过程的质量、动量和能量输送的要求。这些诊断的目标是评估气候模式中已分解的和参数化的动力过程，这是CMIP的一项新鲜事，对于评估平流层对地表气候变化的影响尤为重要。
Diagnostics of atmospheric momentum and energy transport are needed to investigate the origin of circulation biases in climate models and to understand the atmospheric response to natural and anthropogenic forcing. Model biases in atmospheric dynamics are one of the factors that increase uncertainty in projections of regional climate, precipitation and extreme events. Here we define requirements for diagnosing the atmospheric circulation and variability across temporal scales and for evaluating the transport of mass, momentum and energy by dynamical processes in the context of the Coupled Model Intercomparison Project Phase 6 (CMIP6). These diagnostics target the assessments of both resolved and parameterized dynamical processes in climate models, a novelty for CMIP, and are particularly vital for assessing the impact of the stratosphere on surface climate change.
