The results show that this atypical occlusion process was significantly different from the traditional, synoptic-scale occlusion process that occurs within extratropical cyclones. It was caused by the merger of two cold-type mesoscale fronts. One of the fronts developed from the gust front of convective storms, while the other was a sea-breeze front. As the two fronts moved towards each other, the warm air between them was squeezed and separated from the surface. An atypical occluded front was formed when the two fronts merged, with the warm air forced aloft. This kind of occlusion is termed a ＂merger＂ process, different from the well-known ＂catch-up＂ and ＂wrap-up＂ processes. Moreover, local convection was found to be enhanced during the merger process, with severe convective weather produced in the merger area.展开更多

Compared with the USA,the structural relief system is far from perfection on the legislative level and the judicial level.With the implementing of Centralized Examination Methods for Operators and Temporary Provisions of Concentrated Assets and Business Stripping of Operators,the structural relief system in China has been preliminarily established. However,from the technical level,microcosmic element pillar system related to stripping system has not been established yet. According to the experience in law enforcement in the USA,China shall also formulate Handbook on Implementing Relief System in the Antitrust Scrutiny of Operators to provide helpful guide for the structural relief system in China.展开更多
