英文摘要	The generality and some climatological characteristics of the double ridge systems of subtropical high (sh) are investigated statistically by using the daily ncep/ncar reanalysis data from 1958 to 1998. the results show that the sh double-ridge event is a common phenomenon in the northern hemisphere, with the distinct seasonal and regional features, that is, the majority of sh double-ridge geneses concentrate over the eastern north india ocean-western north pacific as well as the central north pacific in the period from mid-july to mid-september. especially over the western north pacific subtropics, the sh double-ridge events are extremely active. it is found that the life cycle of most double-ridge events of western pacific subtropical high (wpsh) is shorter but some still last longer. the wpsh double-ridge events occur most frequently from july to september, while there is a paucity of occurrences during november-march. also, it is shown that the wpsh double-ridge events have a strong interannual variation with a certain periodicity which possesses a remarkably abrupt change in the mid-1970s. additionally, the relationship between the wpsh double ridges and the meridional movement of wpsh is discussed.
