To the leakage characteristic of the fault to the long-distance natural gas pipeline, a method is raised, which is on the basis of wavelet and negative-pressure-wave to detect the leakage and locate. Jobs in this paper are as follows:Multi-resolution decomposition and reconstruction of wavelet transform is utilized to filter the noises, which the leakage brings the noises of negative-pressure-wave. The research is worked in the wavelet and wavelet packet filter. The wavelet transform have a fast and accurate recognition capability to signal singularity.

Because the temperature along the pipeline is not a constant, it changes the velocity of the negative-pressure-wave; the Romberg algorithm of numeric integral and the searching for algorithm are emloyed to locate the leakage.Multi-scale decomposition and reconstruction of wavelet transform is applied to filter the noise of negative-pressure-wave, which was brought by leakage. With the capacity to detect the signal singularity fast and accurately, wavelet transform was used to catch the break point of pressure signal. The work improved the accuracy of Δt in location formula, and the location accuracy is improved.

In DMMCS, there is an alternative distribution of inertial instability column and inertial stability column, at the west and south, there lie negative CVV columns, while negative CVV column is beneficial to deep moist convection.(4) The strong slantwise convection induced by inertial instability, baroclinic instability and conditional symmetry instability will enhance the upper level southerly component. Because of the appearance of the compensated downdraft at the low level of the south side of DMMCS, the low level southerly is intensified, the enhancement of upper- and low-level cores are in favor of the development of DMMCS. And that will do favor for the reinforcement and maintenance of inertial instability, baroclinic instability and conditional symmetry instability, it is a positive feedback process.

深湿对流系统中高层西侧为负MPV2 柱，东侧为正MPV2 柱；(3)深湿对流系统中惯性不稳定柱与惯性稳定柱相间分布，西侧为负CVV 柱，东侧为正CVV 柱，负CVV 柱对深湿对流起激发作用；（4）惯性不稳定、湿倾斜不稳定和条件不稳定产生强的倾斜式对流，而强的倾斜式上升运动加强了深对流系统北侧高层的南风分量，因深对流系统南侧低层出现补偿性下沉气流，因而低层南风加强，高低空急流中心的加强会进一步加强对流的发展，使得惯性不稳定、湿倾斜不稳定和条件不稳定增强和维持，这是一个正反馈过程。
