Abstract:	夏季颱風對於位處太平洋西側的台灣影響甚大，在廣大洋面中常有颱風的前身－熱帶低壓的發生。熱帶低壓能夠發展成颱風仍須有其他環境因素的配合。本文利用TCM-90個案探討當高層有冷心低壓存在時，伴隨冷心低壓的強風輸是否會增強熱帶低壓的高層輻散，進而增強熱帶低壓成爲颱風。研究顯示當熱帶低壓位於高層冷心低壓的西南象限時，伴隨高層冷心低壓的西南強風軸會引起高層輻散場的增強，進而使得低層輻合也增強，因此發展成爲颱風。值得注意的是：當熱帶低壓與高層冷心低壓兩者相距較近時，必須是高層冷心低壓的增強或成熟期。當冷心低壓減弱時，高層強風軸已消失，對於熱帶低壓之發展無所助益。 This paper discuss when upper troposphere cold core low propogating the tropical depression, The hight speed wind axis which following the cold core low will improve the tropical depression's upper divergence. Whi1e tropical depression's upper divergence is increasing, then the lower convergence is also increasing too. That wiI1 strength en the tropical depression to typhoon.
