| 英文摘要 | The impact of typhoon Kujira(2015) on the ocean environment around Yongxing Island in the South China Sea was observed using multiple-satellite sensors and on-site data.A subsurface buoy and Agro float were located to the left and lower right of the track of the typhoon.Satellite observations revealed sea surface cooling of up to 2.5℃,a maximum decrease in sea surface salinity of 2 in the main study area because of heavy rain,and increases in the chlorophyll concentration induced by the slow-moving typhoon with a maximum observed instantaneous wind speed of 35.1 m/s.The sea surface temperature to the right of the typhoon track changed more than that on the left owing to a right bias of the typhoon associated with coupling of the typhoon with wind stress on the sea surface.In the ocean interior,there was obvious downwelling at 24.7 m and upwelling at a depth of 35.7 m with the vertical entrainment and agitation of the typhoon,and the ef fects extended to different depths of up to more than 1 000 m.When the typhoon passed through the main study area,the maximum flow velocity change at depths of 51 and 660 m was about 0.44 and 0.04 m/s,respectively.The typhoon af fected the flow field to a depth of 660 m as it formed and decayed in 11 h,moved at an average speed of 60 m/h,and af fected the sea surface over a range exceeding 700 km as it moved slowly and stayed at sea for 2 d.Vertical entrainment and agitation generated by the typhoon,as well as rainfall,cooled the sea surface.This inhibited the strengthening of the typhoon,but the energy transmitted to the ocean led to divergence-convergence flow from a shallow to deep layer. |
