Figure 2
Horizontal map of a 2-d cumulative near-inertial kinetic energy from the slab model during respective passages of (a) Krosa, (b) Tapah, and (c) Mitag. White circles show accessible ranges for near-inertial waves for periods of three and seven days, which are estimated based on its horizontal group velocity (see Fig. 3e). A yellow star shows location of the FATO station. White dashed curves show a track of typhoon’s migration, with a small circle the position at every six hours. Time-series of the slab model simulations at the FATO station: (d) surface wind velocity, (e) magnitude of wind stress, (f) predicted inertial current, (g) surface wave kinetic energy flux (\(\Pi\)), and (h) cumulative wave kinetic energy (\(\int \mathrm{\Pi dt}\)). In (d–f), eastward and northward components are shown by red and blue, respectively. In (e) and (g), typhoon events of Krosa, Tapah, and Mitag are indicated by inverted triangles, respectively, in red, black, and white, and the gusty event in blue.
