| Research Abstract |
The methodology for the creation of a long-term(1948-2009) frontal data set around Japan was examined. Furthermore, the seasonal march, the annual behaviors, and long-term trends of the frontal zone were revealed on the basis of the frontal data set. The main findings of this study were as follows : 1) The frontal frequencies increase around Japan during July to middle August since the 1990s. 2) The cool summer and the warm winter around Japan in the El Nino years can be explained by the behavior of the frontal zone. 3) The year-to-year variation of the clear-sky ratio in summer was strongly affected by the frontal frequencies.
