Most fast moving cold front was long and narrow banded echo and basically the radial velocity turned from northwest wind to southwest. With the changes of month, the feature of the reflective rate also changed. In winter, the cold front cloud was in layer form. The feature of the reflectivity factors was weak and in large area.

Strong convection cell echo formed in the two sides of the cold front, and it moved with the entire cloud belt. When the dry cold front moved, regional strong convective current formed, mainly by convective cloud and small echo area.

According to the available documents, it can be found out that, among the first generation of new China leaders, MAO Ze-dong, ZHOU En-lai, LIU Shao-qi, ZHU De and DENG Xiao-ping made more statements on the integration of CM and WM due to different division of labor and other historical reasons. This paper will focus on the issue to study the emergence, formation and development of their thoughts on the integration of CM and WM and analyze its process and significance, so as to enlighten the current integration of CM and WM, and even the world＇s integrative medicine.展开更多
