  1. Numerical migration for typical models show that, in contrast to ray method, prestack wave motion migration can correctly image inhomogeneous media, and suppress multiple reflection wave effectively. prestack migration method presented in this paper should be developed to apply in observational teleseismic p waveform data, to study the inhomogeneity of crust and upper mantle

  2. 2. rebuilding of the double sh ridges based on the case of double ridges during the breaking interval of plum - season rainfall in the summer of 1998, it is indicated that the sh ridge would remarkably locate much more southward than its normal position after the phenomenon of double sh ridge is over. furthermore, this southward migration of sh ridge is not sudden but results from the southward rebuilding of the double sh ridges, that is, the northern ( original ) ridge gets enfeebled and disappeared, in contrast, the southern counterpart becomes intensified enough and steadily persists
