Spectrum Analysis of Ocean-Atmosphere Elements for Yongshu Reef During Summer of 1989

  • Publish Date: 1992-02-29
  • In this paper, the power spectrum and cross spectrum are calculated for the Yougshu reef, a marine meteorological observatory, of the Nansha archipelago, with the ocean-atmosphere elements during the summer (from May to August) of 1989. The results show that: (1) in the variation of meteorological elements, there are two low-frequency waves with 30-40 day and 15. 38 day periods, respectively; (2) as to the two low-frequency waves, there is an obvious lag correlation between pressure and wind, also there is clear correlation between low-cloud and wind velocity; (3) the water skin-surface temperature is characterized by quasi-two week oscillation and is correlated to two-cloud evidently. Finally, a discussion is made on the mechanism of synoptic dynamics and the ocean-atmosphere interaction of these correlations.
