中文摘要
研究人员将研究重力波包对中顶区化学放热的影响。化学放热加热是中顶区重要的热源,有大量证据表明重力波与羟基夜光辐射相互作用。一项详细的、随时间变化的研究,包括理解和量化这些波动效应所需的完全非线性化学,尚未进行。研究人员将使用专门为这些任务设计的最先进的模型,包括光谱全波模型,它模拟了一个随时间变化的重力波包,以及一个随时间变化的非线性二维化学模型,它解决了化学活性次要物质的耦合连续性方程。羟基化学将包括在建模中,以更好地理解动力学和气辉排放之间复杂的相互作用。这项研究的主要目的是了解平均状态下小物种分布的强迫以及由波浪引起的相关化学放热加热。这些结果与用于研究全球变化对中层大气影响的全球气候模式有关。
英文摘要
The investigators will study the effects of gravity wave packets on the chemical exothermic heating in the mesopause region. Chemical exothermic heating is an important heat source in the mesopause region, and there is much evidence that gravity waves interact with hydroxyl nightglow emissions. A detailed, time-dependent study including fully nonlinear chemistry required to understand and quantify these wave effects has yet to be performed. The investigators will use state of the art models specifically designed for these tasks, including the Spectral Full-Wave Model, which simulates a time-dependent gravity wave packet, and a time-dependent, nonlinear, 2-D chemistry model that solves the coupled continuity equations of chemically active minor species. Hydroxyl chemistry will be included in the modeling to better understand the complex interplay between dynamics and airglow emissions. The main thrust of the research will be to understand the forcing of the mean state minor species distributions and associated chemical exothermic heating due to waves. The results are relevant to global climate modeling used to study the effects of global change on the middle atmosphere.
