Highlights:
- Four pairs of tropical cyclones (TCs) in the vicinity of Northwest (NW) Pacific have been restudied in this paper by decomposing a total flow into a climatic component and an anomaly (Figure 1) as well as by a simple generalized beta-advection model (GBAM). Results contradict with previous identification that binary interactions occurred in the four pairs of TCs (Figure 2).
- The intensities of the four studied TC pairs were not well equal to each other at the same time during their common lifetime period. The result of GBAM revealed that a stronger TC had a direct influence on the track of a weaker TC but the reverse was not true.
- Whether a binary interaction happens between two TCs and whether the two TCs interact with other anomalous systems can be determined by the GBAM at the optimal level near the maximum center of vorticity anomaly.
