Xie, M.; Yao, S.; Li, W.; Zhao, H., and Gao, Z., 2015. Investigation of the movement characteristics of West Guangdong longshore ocean current system, China.

The West Guangdong Ocean Current (WG current) is a special ocean current flowing along the West Guangdong coastline, China. It has significant impact on the nearshore area, and it will make the nearshore current movement complex after superposing on the tidal currents. A comprehensive investigation of the WG current is mandatory especially to the construction of nearshore harbors. However, at present, the nature of WG current is still not well clarified. Based on a series of filed survey datasets carried out in different representative seasons, the movement characteristics of the WG current are analyzed by using a residual flow extracting method. The results indicate that the WG current direction points to southwest in the entire year, which does not accord with the dominant monsoon direction especially in summer, and the current speed shows significant seasonal variation. The current speed increases at the first 10 km away from shoreline, and then becomes approximately uniform. Besides, the current speed is larger in summer than that in winter.
