| Research Abstract |
The current study conducted numerical experiments using a mesoscale meteorological model to see the influence of variations in topographic shapes and atmospheric fields on generation and maintenance processes of line-shaped convective systems, and also conducted a feasibility examination into controlling torrential rains in the near future. Results in the former showed that the maximum amount of rainfall could decrease by around 20 percent depending on where and to what extent the variations were given. In the latter, the current study obtained certain knowledge of the condition and its mechanism for getting depression effects on torrential rains with more certainty.
