中文摘要
两名研究人员正在进行互补的数值模拟,以了解重力波的传播和频谱演变,以及这些影响在大尺度大气模型中的参数化。 一个采用完全非线性三维波叠加和相互作用的研究,以评估频谱随高度的演变,对波的各向异性和动量通量的影响,从平均和低频波剪切,以及耗散伴随波叠加。 另一个地址波的传播和行为在低频波和平均剪切在热层的高度,三维效果是不重要的,在确定波的振幅和平均流的相互作用。 这两种方法大大修改和更新现有的参数化重力波的影响,采用在几个模型的低层和中层大气和热层。 具体而言,这些修订:(1)更准确地描述波叠加、相互作用和不稳定性的影响;(2)重复观测波的活动、变化和影响;(3)比以前的参数化方案更能扩大到更高的高度。
英文摘要
Two investigators are conducting complementary numerical modeling to gain understanding of gravity wave propagation and spectral evolution and the parameterization of these effects in large-scale models of the atmosphere. One employs fully nonlinear three dimensional studies of wave superposition and interactions to assess spectral evolution with altitude, influences on wave anisotropy and momentum fluxes from mean and low-frequency wave shears, and the dissipation accompanying wave superposition. The other addresses wave propagation and behavior in low-frequency wave and mean shears at thermospheric altitudes where three dimensional effects are not important in determining wave amplitudes and mean flow interactions. Both approaches substantially revise and update existing parameterization of gravity wave effects employed in several models of the lower and middle atmosphere and thermosphere. Specifically, the revisions: (1) more accurately describe the effects of wave superposition, interactions and instability; (2) replicate observations of wave activity, variability and effects; and (3) extend to greater altitudes than previously possible with parameterization schemes.
