分析表明，在气旋初生期，气旋各部位的冷层都有较好的水汽条件；在气旋发展旺盛时，冷锋前和暖锋前的冷层水汽条件较好；在气旋锢囚后，只有暖锋前的冷层和气旋中心水汽较多。

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.
