内容記述 |
In recent years, fears are entertained that severe storms will possibly occur more frequently than before due to global warming. A long term trend of heavy rain occurrence, however, is very difficult to detect because of discreteness of precipitation in time and space. The present study proposes a new approach to analysis for the long term trend of heavy rain occurrence. A logarithmic regression is applied to a histogram of daily precipitation every year. A factor of the logarithmic regression is suggested to represent heavy rain occurrence better than those of exponential and linear regressions. Then, the logarithmic factors have been showing the increasing trends for 47 years since 1961 to 2007, at 22 stations among the total 23 observatory stations under Japan Meteorological Agency in Chugoku and Shikoku area. Although the statistical significance is little at an individual station, the common increasing trend of heavy rain occurrence would be significant for the regional trend. |
