| 摘 要： | 本文着重讨论了对流层中、上层大气环流的演变对低纬度扰动的制约作用。应用两层模式中的扰动振幅方程,按实际的环流形势所确定的风场随纬度和高度的分布,计算了扰动特征相速及其振幅在区域内的分布,考察了南亚——西太平洋地区低纬度扰动的结构和性质。

| Abstract: | In this paper,the evolution of upper and middle tropospheric circulation over South Asia and western Pacific and its constraint on low-latitude perturbances are discussed. Using the perturbation amplitude equation in a two-layer model,based on the meridional and vertical distribution of zonal winds,characteristic phase velocity and amplitude of the perturbance are calculated. On the other hand,the structure and property of the perturbance are also examined. |
