There are two parts in this paper : firstly , a set of single doppler velocity models are presented for typical ambient windfields that include those of being uniform horizontally , macroscale convergence and divergence , which overlap warm and cold advection . which are marked by different signatures in the single doppler velocity field . the models proposed can help users identify useful information from the dopple velocity patterns 本論文包括兩個部分:第一篇通過對典型風(fēng)場的單多普勒天氣雷達(dá)徑向速度圖象進(jìn)行模擬,典型風(fēng)場包括水平均勻一致的風(fēng)場、非均勻水平風(fēng)場的大尺度運動的輻合輻散風(fēng)場以及大尺度運動的輻合輻散風(fēng)場與冷暖平流的迭加等。
