Abstract
<p> In this study, the effects of global warming on tropical cyclones (TCs) were evaluated by using a slab-ocean model coupled with the Atmospheric Global Climate Model (MRI-AGCM) . The warming conditions for the MRI-AGCM climate simulations were obtained from the latest climate models (CMIP6). We have conducted two types of global climate simulations, typical and newly proposed experiments. The former is time slice experiments and latter is the climate experiment fixed single month condition. Both experiments are conducted on present and future periods, to estimate the effects of climate change impacts on TC characteristics. The slab ocean model which considers sea surface cooling due to strong winds, significantly contributes to a reduction in TC intensity. Moreover, we have confirmed that climate change can reduce the TC frequency and enhance the TC intensity.</p>
