“…A pseudo-global warming (PGW) experiment is one method of evaluating the impacts of global warming in the future climate on past TCs. This approach has been applied to typhoons hitting Japan such as Typhoons Vera (1959), Songda (2004), Talas (2011), Canthu (2016, and Lionrock (2016) (Ito et al 2016;Takemi et al 2016;Kanada et al 2017aKanada et al , 2017bNayak et al 2019;Takemi 2019). These studies indicated that extreme typhoons got stronger under the future global warming scenario.…”

“…These studies indicated that extreme typhoons got stronger under the future global warming scenario. Takemi (2019) pointed out that increased precipitable water led to increased rainfall produced by Typhoon Talas (2011) despite the stabilized atmospheric Kawase et al, Impact of historical warming on Typhoon Hagibis (2019) 4 condition in the future climate; Takemi (2019) also indicated that global warming could enhance long-lasting heavy rainfall caused by slow-moving typhoons.…”

“…In this nudging technique, the maximum wavenumber and the nudging coefficient were chosen as 2 and 0.00028 s −1 , respectively. Note that the spectral nudging plays a critical role in better reproducing the tracks of tropical cyclones (Takemi et al 2016b;Takemi 2018a;Takemi 2019). Furthermore, a typhoon bogus scheme which prescribes a Rankine-type vortex was employed to initialize a typhoon vortex at the initial time of the time integration.…”

This study investigated the representation of surface winds in complex terrain during the passage of Typhoon Sondga (2004) in downscaling simulations with the horizontal grid spacing of 200 m. The mountainous areas in Hokkaido where forest damages occurred in the typhoon event were chosen for the present analysis. The 200 m grid simulations were compared with the simulations with the grid spacing of 1 km. The 200 m grid simulations clearly indicated more enhanced and more frequent extremes both in the stronger and weaker ranges of surface winds than the 1 km grid case. Both in the 200 m grid and 1 km grid cases, the mean and maximum winds in the analysis areas during the simulated time period increase with the increase in the terrain slope angle, but in the 200 m grid case, the relationships of the mean and maximum winds against the terrain slope angle includes wide scatter. In this way, the response of the wind representations to the grid spacing appears differently between the 200 m and 1 km grid cases. A parameter characterized subgrid-scale orography was used to quantify the influences of the terrain complexity on surface winds, demonstrating that the area-maxima and spatial variance of surface winds are more enhanced with the increase in the subgrid-scale orography in the higher-resolution case. It is suggested that the high-resolution simulations at the 200 m grid highlight the fluctuating nature of surface winds in complex terrain, because of the better representation of the model terrain at 200 m. Benefits of the representation of surface winds in simulations at the resolution on the order of 100 m are due to the better representation of complex terrain, which enables to quantitatively assess the impacts of strong winds on forest and natural vegetation in complex terrain.

“…The nonhydrostatic dynamics were set for all domains with Lambert conformal conic map projection and were integrated in time with a 30 s time step for the outermost domain. A spectral nudging technique was used on the horizontal wind components and geopotential in the x and y directions of the outer domains with wave number 5 to include synoptic‐scale influences (Cha et al ., 2011; Choi and Lee, 2016; Moon et al ., 2018; Takemi, 2019). Nudging coefficients of 2.8 × 10 −4 s −1 , which correspond to a roughly 1 hr time scale, and nudging‐layer heights from the 200 hPa level up to the model top were used.…”

In August 2016, an unusual occurrence of the landfall of four typhoons in northern Japan caused severe and widespread damage by excessive rainfall and high wind. This study examines the characteristics and structure of these typhoons and the responses to the global warming climate to explore the robust features of typhoon hazards in northern Japan in a future warming climate. By obtaining similar typhoon tracks under the 2016 conditions and a pseudo global warming (PGW) climate, we found that the typhoon intensity under the PGW climate becomes stronger with higher lifetime maximum wind up to~10 mÁs −1 and lower lifetime minimum sea level pressure of~20 hPa. Rainfall associated with the typhoons indicated a robust increase in northern Japan in the PGW climate, while the changes in surface winds in the PGW climate depend on the case. A higher rate of intensification and more availability of energy are expected in the future warming climate especially over the landfall regions. All the typhoons except Typhoon Lionrock, after making landfall over Hokkaido region, exhibited a much deeper cold core structure in the future climate. Overall results suggest that the hazards related to typhoons over northern Japan will be more severe in the future warming climate.
