中文摘要 | 本文利用1983-1987年5-6月梅雨季地面每6小時資料,以0.5 × 0.5度經緯度網格方塊,分析臺灣地區中尺度低壓之氣候特徵,探討其頻率之時空分佈、生命期、旋生強度與強度日夜變化。 發現主要旋生區在臺灣東南近海、西北部與西南部沿海,生命期平均為15.5小時,東側者較西側者為長,且強度較強,海上者亦較陸上者為強。中尺度低壓之形成與強度日夜變化,可能均受氣壓半日波影響,唯強度大者所受影響較小。 |
英文摘要 | Mesolows in the Taiwan Mei-Yu seasons of 1983-1987 were analyzed for each 0.5×0.5 degree latitude-longitude grid square using 6 hourly surface observations. Spatial and temporal distribution of the mesolow frequency was investigated. The intensity and its diurnal variation were studied. It was found that the mesolows tended to form over the area to the southeast, northwest and southwest of Taiwan. The mean life time was about 15.5 h and it was longer over the eastern side of the Central Mountain Range than over the western side. The mean intensity of emsolow was stronger over the ocean as compared the that over the land was stronger over the eastern side than over the wetern side. The formation and the diurnal variation of mesolow appeared to be affected by the semi-diurnal pressure wave. The strong mesolow were affected to a lesser degree than the weaker ones. |
