The terrain conditions considered in the numerical model are three folds: first, a flat terrain with the altitude 1m above mean sea level; second, an idealized line-shaped mountain terrain; third, a complex terrain using GTOPO30. Although an accumulated rainfall due to Typhoon 0514 is recorded higher than 1,000 mm, a calculated one using the flat terrain is 250-300 mm. The calculated rainfall using the complex terrain becomes 200-300% (500-900 mm) in comparison to flat terrain case. This discrepancy is found to cause by blocking and evolving the convective cells, which are generated by lifting up the water vapor along the mountain slope in the windward areas. A ratio of the forecasted rainfall with/without orography provided an important index for the risk of the heavy rain in the tropical cyclone.}, pages = {190--198}, title = {Orographical Effects of Heavy Rainfall by Typhoon 0514 (NABI)}, volume = {9}, year = {2008}, yomi = {カモハラ, サヤカ and スギオ, サトル and タナカ, ケンジ and カモハラ, サヤカ and ヤマダ, フミヒコ and オオモト, テルノリ and スギオ, サトル} }
