中文摘要 | 本文主要探討在民國87年第2個侵臺颱風--奧托(OTTO)的發生經過、路徑、強度 、侵臺期間各氣象要素和主客觀預報模式的校驗及災情做分析探討。奧托颱風於呂宋島東方 海面形成,隨即向西北方向朝臺灣接近, 其中心於 8 月 4 日 12 時 20 分 (地方時 ) 登 陸臺東縣成功鎮,再穿過中央山脈由臺中梧棲出海,進入臺灣海峽登陸中國大陸,迅速減為熱 帶性低氣壓。奧托颱風侵臺期間,其最強風力出現在蘭嶼,達 68.2m/s(17 級風以上 ),降 雨方面則在阿里山有 412.5 公釐,其他阿里山及高屏山區亦有 250 公釐以上,其造成的災 害主要發生在臺灣中南部, 共有 1 人死亡, 1 人失蹤,農業、水利及交通損失達 3 億 3 千萬元。路徑預報方面,中央氣象局 24 小時和 48 小時的誤差分別為 188 公里和 548 公 里。 |
英文摘要 | This article mainly deals with typhoon Otto(9802) about its origination, evolution, track and meteorological factors. Discussions on its verification of various subjectives and objectives tracking forecasts are also included. Otto originated over the ocean east to Luzon of the Philippines and then moved northwestly toward Taiwan. Its center landed on the Chen-kung town (Tai-tung) and later moved off, land to the sea from the Tai-chung area. After passing through the Taiwan Strait, it made a second landfall on Mainland China, and finally dissipated as a tropical depression over land. The observations shows that there was a peak gust of 68.2 m/s observed at Lan-yu. Owing to the effects of cloudbands within the southwest quadrant of Otto and the topography of Taiwan, a maximum accumulated rainfall of 412.5mm was observed at the A-li-shan and also the heavy rain near its mountain area during Otto's passage. Severe property damages and losses of life in the south part of Taiwan were reported. The 24hr and 48hr official forecast errors of the CWB were 188km and 548km respectively. |
