摘要：

Using the techniques of empirical orthogonal function analysis and the change-point analysis to total summer rainfall from 60 weather observation stations, it was found that total summer (from June to September) rainfall in Korea has increased greatly since 1998. The increase level was higher in the season between Changma and late summer rainy season (from the end of July to early August) and in the season after late summer rainy season (after the early September). Among the reasons for increase of summer rainfall in Korea since 1998, the north-high and south-low pressure pattern formed around Korea drew attention. As northeasterlies and southeasterlies derived from these two pressure systems converged in Korea, rainfall and moisture convergence increased most in Korea of the East Asia regions (0-60A degrees, 100-180A degrees E). In addition, the atmosphere above Korea revealed that there were strong ascents from the ground to 200-hPa level with the warm air to 500-hPa level.
