Conclusions

  • Among all models, MPI’s models and GFDL’s models relatively well reproduce the ENSO signals just like in the observations in their historical run.

  • It has shown in the observational reanalysis that the El Nino could cause stronger anticyclone over the western north Pacific which will ultimately lead to more precipitation over the East Asia in the next summer.

  • Especially, GFDL’s models relatively well reproduce the ENSO-East Asian summer monsoon relationship.

  • However, even the models known as good performances didn’t properly reproduce the ENSO-induced variability of the East Asia Summer Monsoon.

  • Hence, there’s still much to be examined and improved for those relationship.
