摘要

本丈引用一特殊糾正方法來間接評估垂直速度之三度空間分佈情形。冬季寒潮爆發，實為低緯度一重要之天氣現象，因而選用了四個冬季寒潮爆發個案，引用O'Brien（1970）之方法對其合成之高低氣壓做分析，結果顯示最大上升下降速度發生地區有別於其他非寒潮爆發之個案研究。對於水平及垂直方面之垂直速度分佈以及雷達觀測報告均以圖分析並加討論。

An analysis for the kinematical vertical motions has been carried out by using O'Brien's (1970) special adjustment technique. A composite case, including four cases of winter time polar air outbreaks, was used for present study. Detailed three-dimensional vertical velocity field together with the radar reports are presented and discussed. Results show that an area of maximum vertical motion usually located at different position in relation to the surface center in contrast to the results in different individual case studies, which did not use polar air outbreak cases, made by some other researchers.
