Current observations in the southern Yellow Sea in summer
摘要
Abstract
Current data from three moored Acoustic Doppler Profilers (ADPs) deployed in the southern Yellow Sea at sites A (124.17°E
34.82°N)
B (122.82°E
35.65°N) in summer 2001 and site C (120.85°E
34.99°N) in summer 2003 were analyzed in this paper. Features of the tidal and residual currents were studied with rotary spectral and cross-spectral methods. Main achievements were as follows: 1) Tides dominated the currents. At sites A and B
the semidiurnal tidal current was basically homogeneous in the whole depth
taking a clockwise rotation at site A
and near-rectilinear counterclockwise rotation at site B; while the diurnal tidal current was strong and clockwise near the surface
but decreased and turned counterclockwise with depth; at site C
semidiurnal tidal current dominated and diurnal current took the second
both of which were counterclockwise and vertically homogeneous. Inertial motion contributed to the clockwise component of diurnal fluctuations; 2) The 3–5d fluctuation of residual current was found at site C and attributed to the response of current to meridional wind
with a lag time of approximately 1.8d; 3) Mean residual flows at sites A and B in 2001 probably suggested an anticyclonic inner circulation in the middle of the southern Yellow Sea in summer.
