Abstract In this study, a new index is defined to capture the prominent northward propagation of the intraseasonal oscillation (ISO) in boreal summer in the East Asian and western North Pacific (EAWNP) region. It is based on the first two modes of empirical orthogonal function (EOF) analysis of the combined fields of daily anomalies of zonally averaged outgoing longwave radiation (OLR) and 850-hPa zonal wind (U850) in the EAWNP region. These two EOFs are well separated from the rest of the modes, and their principal components (PCs) capture the intraseasonal variability. They are nearly in quadrature in both space and time and their combination reasonably well represents the northward propagation of the ISO. As no future information beyond the current date is required as in conventional time filtering, this ISO index can be used in real-time applications. This index is applied to the output of the 24-yr historical hindcast experiment using the Global Environmental Multiscale (GEM) model of Environment Canada to evaluate the forecast skill of the ISO of the EAWNP summer monsoon.

Japanese Identity

In the pre-modern period, Japanese identity was articulated in contrast with China. It was, however, articulated in reference to criteria that were commonly accepted in the whole East-Asian cultural sphere; criteria, therefore, that were Chinese in origin.One of the fields in which Japan's conception of a Japanese identity was enacted was that of foreign relations, i.e. of Japan's relations with China, the various kingdoms in Korea, and from the second half of the sixteenth century onwards, with the Portuguese, Spaniards, Dutchmen, and the Kingdom of the Ryūkū.
