| 摘 要： | Low frequency (LF) current (period>25 hour) variation at 5 stations in Jiaozhou Bay. Shijiousuo, and the central part of the Yellow Sea were studied by analyzing the observed long-period current data series in the study area.1) There are obvious periods of 3 and 5 days in the LF current spectra. The energy spectral value of LF current of a 5 day period is remarkably larger than that of a 3 day period. These periods reflect the correlations between the LF current variation and the LF water level variation.2) The feet that the 15-day period in the LF current spectra corresponds to the semi-monthly celestial tide period indicates that the tide-induced residual current is an important and most evident LF current component in the bay.3) The LF current spectral energy density in the northward direction is much larger than that in the eastward direction. This shows the frequency and strength of the wind field in the northward direction are evidently larger than that in the eastward direction.

| Abstract: | Low frequency (LF) current (period >25 hour) variation at 5 stations in Jiaozhou Bay, Shijiousuo, and the central part of the Yellow Sea were studied by analyzing the observed long-period current data series in the study area. - There are obvious periods of 3 and 5 days in the LF current spectra. The energy spectral value of LF current of a 5 day period is remarkably larger than that of a 3 day period. These periods reflect the correlations between the LF current variation and the LF water level variation.
- The fact that the 15-day period in the LF current spectra corresponds to the semi-monthly celestial tide period indicates that the tide-induced residual current is an important and most evident LF current component in the bay.
- The LF current spectral energy density in the northward direction is much larger than that in the eastward direction. This shows the frequency and strength of the wind field in the northward direction are evidently larger than that in the eastward direction.
