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

Figure 1

Tracks of Typhoons Tembin and Bolaven (a) and a “Fujiwhara” diagram for the binary interaction between them (b) from 0000 UTC 20 August to 0000 UTC 1 September (interval: 6 hours; red dots: Tembin; blue dots: Bolaven). In (b), distances are in degrees latitude. Dots are centroid-relative positions. The major elements of “Approach”, “Capture”, “Orbit”, and “Escape” are labelled. The radius of dash circle is 6.5 degrees. The origin of coordinate denotes the geographical center between the two vortices.
