Abstract
In this study, future projection onto regional heavy precipitation in Gifu and Aichi Prefectures is evaluated for the period from 2090 to 2099 by a pseudo global warming experiment using the products of the HadCM3 SRES A1B scenario run. Due to the global warming, the annual maximum daily rainfall becomes 1.5-2.0 times and the annual number of daily rainfall event greater than 100 mm is also increased by about 1.0 days. On the other hand, there are spacial differences that the impacts of the global warming are relatively small around the central part of Gifu Prefecture (corresponding to an inland mountainuous region). It is considered that, in the future climate, low-level moisture advection over the inland mountainous region is inhibited so that the heavy rainfall area shifts to the southern part of Gifu Prefecture (corresponding to an upwind lowland region).
