Numerical Analysis on the Effects of Binary Interaction between Typhoons Tembin and Bolaven in 2012

Figure 6

Tracks of Typhoons Tembin and Bolaven (a) and a “Fujiwhara” diagram for the binary interaction between them (b) in the NoM experiment from 1200 UTC 23 August to 1200 UTC 27 August (interval: 6 hours; red dots: Tembin; blue dots: Bolaven). In (b), distances are in degrees latitude. Dots are centroid-relative positions. The radius of dash circle is 6.5 degrees. The origin of coordinate denotes the geographical center between the two vortices. The 500 hPa streamline at 0000 UTC 25 August as well as the 850 hPa wind fields (interval: 3 m s⁻¹) in the CTL (c, e) and NoM experiments (d, f).
