Why is it important?

Dynamical mechanism that may cause the inter-annual variability of the Rossby wave frequency from near Japan to its east has not been clarified as yet. Although the statistical relationship between the Rossby wave frequency over the North Pacific and the El Niño Southern Oscillation is suggested by previous studies, the related process was not been revealed.


This line of approach is important to further understand the impact of El Niño Southern Oscillation on the summer Asian monsoon and the related large-scale atmospheric circulation, and climate condition over East Asia during the boreal summer.
