| 中文摘要 | 海棠(HAITANG)颱風是民國94年在北太平洋西部形兼的第5個颱風,為當年第1個侵台的颱風,也是近5年來第1個侵台的強烈颱風。海棠颱風於7工12日00UTC在關島北北東方海面形成後,開始以西北西方向移動,隨後轉向西南西,然後想轉偏西進行,16日06UTC後想朝西北西移動,此期間其強度不斷地增強而達到強烈颱風強度。17日00UTC後再轉西北前進,當颱風中心於17日18UTC行進到花蓮東方近海時,原西北走向的路徑突然改變,颱風中心開始略向南偏移,隨後再逐漸向北偏移,打轉了一圈後在18日14時50分從宜蘭東澳附近登陸,之後通過北部陸地,於18日22時左右由苗栗後龍附近出海。海棠颱風炎來之強勁風力及豐沛雨量,為台灣地區造成嚴重災情。在風力方面,台灣各地區出現的最大陣風除嘉義、阿里山及離島之金門外,皆在10級以上;尤其是花蓮達17級,蘭嶼及彭佳嶼更高達17級以上強陣風。降雨方面,中南部山區、東北部宜蘭山區及東南部地區總累積雨量皆超過1000毫米,尤其是在高屏山區超過2000毫米,另外,海棠颱風侵襲期間,台東地區有焚風現象發生。 在颱風路徑預報誤差校驗方面,中央氣象局24小時預報平均誤差為78公里,而48小時路徑預報平均誤差為106公里。 |
