Fujiwara and Kawamura ( 2021, hereafter FK21) revealed the modulations of TC intensity and structure through the remote impact of large-scale SST changes over the Kuroshio in boreal fall. On the other hand, several recent studies have pointed out the significant role of remote ocean environments in TC strength (Fujiwara et al., 2017, 2020a, 2020b Hegde et al., 2016). Under these backgrounds, a lot of studies regarding the local influence of ocean conditions associated with the WCEs on TC intensity have been conducted for the real TCs such as Hurricane Opal (Shay et al., 2000), Hurricane Katrina (Wu et al., 2007), and Typhoon Soudelor (Li & Huang, 2019) and for the idealized TC (Sun et al., 2020). A statistical research has reported that the regions where intense TCs are observed correspond to those of active WCEs, and 70% of observed TCs over the Western North Pacific encounter the WCEs at least one time (Ma et al., 2017). Mesoscale warm ocean eddies, referred to as warm-core eddies (WCEs), is particularly important in TC intensification (Hong et al., 2000 Shay, 2010). The non-homogeneous ocean structures related with mesoscale ocean eddies have a significant impact on tropical cyclone (TC) intensity (e.g., Liang et al., 2018 Lin et al., 2005, 2008 Ma, 2020).
