In this context conventional and non - conventional observations ( cdw ) are assimilated by mm5 adjoint - model assimilation system so as to do research on the quality of the assimilation system and the role of cdw in improving the prediction . in this text the principal of constructing mm5 adjoint - model assimilation system is introduced amply 本文就是利用mm5伴随模式同化系统，同化常规观测资料以及非常规资料(云导风资料) ，以研究该同化系统的特性以及卫星云导风资料对于改善预报所起的作用。
In this paper , based on the micaps meteorology data during 2000 - 2002 provided by china weather bureau , the routine observation data from march to may in sand - dust weather provided by qingdao weather bureau , and ep / toms satellite observation data , the dry deposition of sand aerosol data from february 2002 to february 2003 in beijing and from may 2001 to december 2001 in qingdao , author analyzed the processes about source , transportation and deposition on the sea in east asia in recent years 本文利用中国气象局提供的2000 2002年micaps气象资料、青岛市气象局提供的2000 2002年3 ? 5月沙尘天气的常规观测资料； ep toms卫星观测资料；北京2002年2月2003年2月和青岛2001年5月2002年12月气溶胶干沉降资料，主要分析了2000 2002年东亚沙尘气溶胶的源地、入海途径、对我国东部海域影响概率和入海通量。
The first diagnostic analyses show that the heavy rainfalls are produced together by vortex , shear line and upper and lower jets , meiyu front . the condition of high energy , saturation , potential instability is propitious to the form and maintenance of heavy rainfall . the result of numerical simulation by mm5 model shows that heavy . rainfall has close relation with meso - scale vortex pole and strong convection 采用ncep全球谱模式和常规观测资料对“ 03 . 7 ”江淮地区的两次暴雨过程的影响系统及其可能机制进行了初步诊断分析，发现梅雨暴雨是受低槽、低涡、切变线、高、低空急流和梅雨锋区共同影响造成的，该地区维持高能、饱和、潜在不稳定的环境，有利于暴雨的产生中尺度数值模式( mm5 )模拟结果表明梅雨暴雨与中尺度涡柱、强对流运动密切相关。
We carried out some test and routine observations , and by the data analyses we conclude : 1 ) this system can improve the contrast and spatial resolution of the filtergram and magnetogram obviously ; 2 ) the optimization of the algorithm largely improve the temporal resolution , and this makes the routine observation possible 通过对试观测和常规观测数据的分析，我们发现： 1 )该系统能够大大提高单色像、磁场数据的对比度和空间分辨率； 2 )对相关跟踪算法的优化大大提高了系统的时间分辨率，系统可以投入常规观测使用。
