• Change in the North Pacific subtropical gyre due to global warming and its climatic influence

  Project Period (FY)： 2019/04  -  2022/03  Investigator(s): Kobashi Fumiaki

  Grant-in-Aid for Scientific Research(C)  Principal Investigator  19K03969 

  Analyzing historical hydrographic observations and large ensemble data of the past climate simulation based on climate models, we examine the change in the North Pacific subtropical thermocline and mode waters. We found that the main thermocline becomes deeper in the area off the North America continent and along the southern side of the subtropical gyre, which suggests that the lower subtropical gyre has weakened due to global warming. In addition, we found changes in the thermocline in association with subtropical mode water and central mode water and showed the importance of mode waters especially in the changes in the surface temperature.
