项目摘要
The source of gravity waves in the region 80km - 100 km is from the troposphere and stratosphere, and the ability to divine common sources can be achieved by ray-tracing techniques. Ray tracing methods are here enhanced by a three-fold research effort that first addresses the traditional limitation of application to slowly varying gravity waves. Our approach includes treatment of rapidly varying waves generated by tropospheric convection. The second task of the research is reconciliation of the classical dispersion formalism in both Eularian (ground-based) and Lagrangian (with the wave) reference frames, which to date appear to produce differing ray-trace results. Finally, this effort expands common ray trace methods to include wave propagation through a realistic, three-dimensional atmosphere rather than the steady-state approximations used to date.
80 km- 100 km区域的重力波震源主要来自对流层和平流层,射线追踪技术可以探测到共同的震源。 射线追踪方法在这里增强了三倍的研究工作,首先解决了传统的限制应用缓慢变化的重力波。 我们的方法包括对流层对流产生的快速变化的波的治疗。 研究的第二个任务是调和经典的色散形式主义在欧拉(地面)和拉格朗日(与波)参考框架,到目前为止似乎产生不同的射线跟踪结果。 最后,这项工作扩展了常见的射线追踪方法,包括波传播通过一个现实的,三维的大气,而不是稳态近似使用日期。
