摘要Using surface and aerological meteorological observations obtained at the Xisha Automatic Weather Station and three moored buoys along the continental slope, characteristics of the synoptic-scale disturbances over the northern South China Sea (NSCS) are extensively studied. The power spectra of surface and aerological observations suggest a synoptic feature with a pronounced energy peak at a period of 5-8 d and a weak peak at 3-4 d. The standard deviation of the synoptic temperature component derived at Xisha Station from 1976 to 2011 indicates that the strongest variability normally exists in August all through the whole troposphere. At the interannual scale, it is found that El Nio plays an important role in regulating the synoptic disturbances of atmosphere. The vertical synoptic disturbances have a double active peak following El Nio condition. The first peak usually occurs during the mature phase of El Nio, and the second one occurs in the summer of decay year. Comparing with the summer of developing years, the summer of the decaying year of El Nio has more active and stronger synoptic disturbances, especially for the 5-8 d period variations.
