“…This vigorous poleward western boundary current creates a complex ocean current system when it flows over steep topography northeast of Taiwan where canyons often cut through the continental slope (e.g., X. Guo et al., 2006, 2003; Hsueh et al., 1993, 1997, 1992; Tang et al., 2000; Yang et al., 2012, 2018, 2011). Moreover, this current system becomes even more complex due to the energetic interactions between the Kuroshio and westward propagating mesoscale eddies that originate from the tropical North Pacific (e.g., Vélez‐Belchí et al., 2013; Y. Zhang et al., 2020).…”

“…Compared with the scheme based on wind speed, schemes based on wave state describe the physical state of the sea surface more directly and are often used in the atmosphere-ocean-wave coupling model, in which the wave state is provided by the ocean model or the wave model. e heat transported from ocean to atmosphere is the main energy source for typhoon [30,31]. Due to the difficulties in measuring heat flux directly, the mechanism of airsea heat transfer is relatively dubious.…”

The Coupled Ocean-Atmosphere-Wave-Sediment Transport model has been used to simulate Super Typhoon Yutu (2018). The impacts of four momentum transfer parameterization schemes (COARE, TY, OT, and DN) and three heat transfer parameterization schemes (COARE, GR, and ZK) on typhoon modelling have been studied by means of the track, intensity, and radial structure of typhoon. The results show that the track of Yutu is not sensitive to the choice of parameterization scheme, while the combinations of different parameterization schemes affect the intensity of Yutu. Among the four momentum flux parameterization schemes, three wave-state-based schemes (TY, OT, and DN) provide better intensity results than the wind-speed-based COARE scheme, but the differences between the three wave-state-based schemes are not obvious. Among the three heat flux parameterization schemes, the results of the GR scheme are slightly better than those of the COARE scheme, and both the GR and COARE schemes are significantly better than the ZK scheme, from which the intensity of Yutu is underpredicted obviously. The influence of the combination of different parameterization schemes on the intensity of the typhoon is also reflected in the radial structure of the typhoon, and the radial structure of the typhoon simulated by experiments with stronger typhoon intensity also develops faster. Differences of intensity between experiments are due mainly to the differences in sea surface heat flux, the enthalpy transferred from sea surface to the atmosphere has a significant impact on the bottom atmosphere wind field, and there is a strong correspondence between the distribution of enthalpy flux and the bottom wind field.

“…Under the globally warming atmosphere and ocean, sequential typhoons have increasingly significant effects on the ecological environments of oceans and coastal residents, so the interaction between sequential typhoons and oceans has attracted an increasing amount of attention [25][26][27]. However, their studies did not distinguish between different mesoscale eddy features: a dynamic feature that is ubiquitous in the ocean [33] and important for the typhoon-ocean interaction [67]. Yang et al [25] and Wu et al [26] mainly showed the responses in the CEs, and the research results of Zhang et al [27] were mainly based on observations of Station 2 located in an AE.…”

“…The sequential typhoons studied in the past almost occurred in the SCS, and the NWP is the region with a high frequency of typhoon genesis [31], accounting for more than twenty typhoons every year [32]. In addition, the NWP is also one of the most active mesoscale eddy regions, in which the Kuroshio has rich ocean dynamic characteristics, such as ubiquitous mesoscale eddy movement [33]. Due to the large-scale flow, typhoons generated in the NWP tend to move northwestwards, and the landfalling typhoons will cross the Kuroshio.…”

Four sequential tropical cyclones generated and developed in the Northwest Pacific Ocean (NWP) in 2014, which had significant impacts on the oceanic environment and coastal regions. Based on a substantial dataset of multiple-satellite observations, Argo profiles, and reanalysis data, we comprehensively investigated the interactions between the oceanic environment and sequential tropical cyclones. Super typhoon Neoguri (2014) was the first typhoon-passing studied area, with the maximum sustained wind speed of 140 kts, causing strong cold wake along the track. The location of the strongest cold wake was consistent with the pre-existing cyclonic eddy (CE), in which the average sea surface temperature (SST) cooling exceeded −5 °C. Subsequently, three tropical cyclones passed the ocean environment left by Neoguri, namely, the category 2 typhoon Matmo (2014), the tropical cyclone Nakri (2014) and the category 5 typhoon Halong (2014), which caused completely different subsequent responses. In the CE, due to the fact that the ocean stratification was strongly destroyed by Neoguri and difficult to recover, even the weak Nakri could cause a secondary response, but the secondary SST cooling would be overridden by the first response and thus could cause no more serious ocean disasters. If the subsequent typhoon was super typhoon Halong, it could cause an extreme secondary SST cooling, exceeding −8 °C, due to the deep upwelling, exceeding 700 m, surpassing the record of the maximum cooling caused by the first typhoon. In the anti-cyclonic eddy (AE), since the first typhoon Neoguri caused strong seawater mixing, it was difficult for the subsequent weak typhoons to mix the deeper, colder and saltier water into the surface, thus inhibiting secondary SST cooling, and even the super typhoon Halong would only cause as much SST cooling as the first typhoon. Therefore, the ocean responses to sequential typhoons depended on not only TCs intensity, but also TCs track order and ocean mesoscale eddies. In turn, the cold wake caused by the first typhoon, Neoguri, induced different feedback effects on different subsequent typhoons.
