*2.2. Data*

The HYCOM reanalysis results (GLBu0.08/expt\_19.1, including surface elevation, horizontal velocities, water temperature and salinity) in the SCS from 16 October to 20 November 2010 were used to analyze the ocean dynamical response to typhoon Megi. These data have a spatial resolution of 1/12.5◦ and a temporal interval of 3 h, which are available from www.hycom.org/data/glbu0pt08/expt-19pt1 (accessed on 1 January 2021). The wind forcing used in the HYCOM is the 1-hourly National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) wind data, which captured typhoon Megi [37]. Additionally, note that the Navy Coupled Ocean Data Assimilation (NCODA) system was used for data assimilation when generating the reanalysis data. In addition, to validate the HYCOM reanalysis results, the bandpass filtered NIWs at mooring UIB6 (Figure 1) were used in this study, which are cited from [37].
