Effect of Typhoon Kalmaegi (2014) on northern South China Sea explored using Muti-platform satellite and Buoy observations data

•The current velocity to the right side of the track decays faster than that to the left side.•Water temperature response to the right side of the track exhibits a three-layered ‘cooling–warming–cooling’ structure in the vertical.•Storms with tracks similar to that of Kalmaegi (2014) may induce similar maximum cooling in the northern SCS.
