The force of low-level frontal zone disturbance is a major factor of the development of middle and low level cyclone. The large center of negative geopotential perturbation inversed by low-level disturbance potential vorticity is located in the front of cyclone providing a favourable condition for the eastward moving and development of cyclone. The high-level system plays a role of indirect force action. The interaction of the development of high-level trough and ridge and low-level frontal zone becomes an important mechanism of the developing of cyclone.

低层锋区扰动强迫是中低层气旋发展的最主要因子，低层位涡扰动反演所得的负位势扰动大值中心位于气旋的前方，有导前现象，为气旋继续东移、发展提供一个铺垫；高层系统起着间接强迫作用，高层槽脊系统的发展和低层锋区的相互作用所导致的斜压扰动成为气旋发展的重要机制。

Results Xunhua-Guide area is characterized by step-shaped low-relief at different elevation. The low-relief surfaces developed above the newer strata in sedimentary basin among the Oligocene to the lower Pleistocene are in higher elevation, but above the older strata, are in lower elevation. The elevations of all above low-relief surfaces are lower than those of the planation surface above the bedrocks in the thrust belts. The low-relief surfaces of terraces, developed on both sides of the deep-cutting valleys within the basins, are lowest in elevation.

结果 循化－贵德地区地形形态总体呈台阶状结构，在不同海拔高度存在低起伏地形；发育于盆地沉积地层之上的低起伏面表现为年代越新的地层之上低起伏面高程越高，越老的地层高程越低，并且它们均低于发育于逆冲带基岩之上的夷平面；发育于盆地深切河谷两侧阶地之上的低起伏面海拔高程总体较低。
