日本中部的地形特征非常显著，中部是阿尔卑斯山的高山，沿海地区是大平原，南北两侧分别面对太平洋和日本海，海岸线复杂。因此，在夏季，各种类型的本地流发展。在这种情况下，空气污染物从高度发达的城市地区到山区农村地区的中程输送引起了日本应用气象学和大气环境领域许多人的关注，因为它发生在几种类型的当地风的有趣组合中，例如陆风和海风，山谷风和平原-高原风，夏季的重复运输可能对山区生态系统造成严重破坏。栗田等人（1985）指出，东京湾地区排放的污染物迁移到日本中部的山区，即一天内约150公里的行程。这一距离远远超过了中纬度单纯海风情况下的预期，表明海风、谷风和平原-高原风的共同作用对输送的重要性。后来，Kondo（1990）使用中尺度气象模式数值验证了日本中部高于2000 m的高山的存在是造成污染物中程输送的气流形成的关键。Kitada等人（1998）还讨论了日本中部高山在太平洋一侧沿海平原地区海风时间变化中的主导作用，即，诺比平原如前所述，10多年前就已经清楚地表明，从东京等日本沿海大城市释放的污染物可以在12小时内输送150公里以上，主要是在白天，并到达山区。
The Central Japan has notable topographical features such that high mountains of the Japanese Alps exist at its center, large plains extend in its coastal area, and it is bounded with complex coast lines at the south and north sides facing to the Pacific Ocean and the Sea of Japan, respectively. Thus various types of local flows develop in summer season. In this situation, medium range transport of air pollutants from highly developed urban area to mountainous rural area has attracted concern of many people in applied meteorology and atmospheric environment in Japan, since it occurs in an interesting combination of several types of local winds such as land and sea breezes, mountain and valley winds, and plain-plateau winds, and the transport repeated in summer season probably causes severe damage to eco-systems in the mountainous area. Kurita et al. (1985) pointed out that the pollutants discharged in Tokyo Bay area migrate to the mountains in central Japan, i.e. the travel distance of about 150 km within one day. The distance far exceeded what was expected in simple sea breeze situation in mid-latitudes, and thus the phenomena suggested importance of combined effects of sea breeze, valley wind, and plain to plateau wind for the transport. Later Kondo (1990) numerically verified using meso-scale meteorological model that the presence of the high mountains in the central Japan, which are taller than 2000 m, is a key for the formation of the flow resulting in the medium range transport of pollutants. Kitada et al. (1998) also discussed dominant role of the high mountains of the central Japan in temporal variation of sea breezes over coastal plain area in the Pacific Ocean side, i.e., the Nohbi Plain. It was made clear more than 10 years ago, as noted above, that the pollutants released from huge urban areas in the coastal Japan such as Tokyo can be transported more than 150 km within 12 hours mostly during the daytime and reach to the mountains.
