Disaster of embanks often happen under flood and rainfalls. In order to analyze the influences of water level variation and rainfall on the distribution of seepage and embankment's stability, in this paper, the change of seepage field under the condition of different water level or rainfall is studied based on the saturated-unsaturated seepage theory. And the safety factor of embankment's stability is calculated based on the theory of unsatutated-soil shear stress to search for the action of various factors.

A typical case of polar low occurred on 26 February 1996 over the Sea of Japan is investigated. The analysis exhibits the spatial structures at different stage of this polar low event. At the initial stage of the polar low, the largescale environmental condition is characterized by a strong baroclinic zone in the low-level (below 700 hPa). The upper-level environmental circulation is almost barotropic. At the mature stage, a high IPV anomaly is situated over the surface polar low and a shallow layer of instability overtops the polar low center.
