| Research Abstract |
We developed a group of atmospheric models having different levels of complexity. They are used cooperatively to examine the mechanisms of dominant circulation variability and clarified, for example, forcing processes for the summertime teleconnection patterns. We also developed an experimental forecast system based on the ensemble Kalman filter. By extending the system such that the model's parameters are assimilated and perturbed, we showed an improvement in the 1-mo forecast skill, which is due to the reduction of the model error.
