摘要(中) 本文利用中壢特高頻雷達在利奇馬颱風侵台期間 (2001年9月24日至28日)所做的連續觀測資料中,以28日當地時間08:00至10:00之間的強對流系統事件作個案分析。在本研究中,觀測資料根據動差法求得的回波功率、都卜勒速度、頻寬、訊號雜訊與頻譜,配合DSD理論方法逼近中性大氣及降水頻譜,從而了解背景大氣與降水參數在颱風對流系統期間的關聯性,同時試以基波轉換分析法討論中性大氣垂直徑向速度的波動現象。 摘要(英) The thesis is focus on the strong convective system event of 0800 LT to 1000 LT, date 28, Sep., 2001. It was observed with the Chung-Li VHF radar during the typhoon Lekima approaching to Taiwan Island. In this research, the observed data is according to the moment methods to get the echo power, Doppler velocity, velocity width, signal to noise ratio and spectra. Besides, the thesis uses the DSD theory to fit the spectra of clear air and precipitation. The purpose is to understand the relations between clear air and precipitation parameters during the convective system of typhoon Lekima. Finally, the thesis includes the wavelet transformation to discuss wave motions of the vertical velocity of the clear air. 關鍵字(中) ★ 對流系統
