Internal Dynamics Related to the Appearance of the Okhotsk High in Midsummer
Access this Article
The upper-level anomaly pattern corresponding to the appearance of the midsummer surface Okhotsk high is identified. It is confirmed that the pattern is well correlated with surface air temperature anomaly in northern Japan. Positive kinetic energy conversion from the basic field to the anomaly field is estimated, corresponding to the anomaly pattern. The steady response patterns are calculated by a linearized numerical model, giving forcings distributed over the entire Northern Hemisphere. The statistical analysis for the responses detects an anomaly pattern similar to that obtained in the observational analysis. These results suggest that the anomaly pattern associated with the appearance of the Okhotsk high can appear, in relation to the structure of the basic field, even if external forcings are homogeneously distributed.
