By the use of GPS and CINRAD, a physical test was conducted for the operation of weather modification in Guangxi on February 16, 2008. It shows that after the cloud seeding, microphysical changes in the supercooled clouds may lead to the enhancement of the basic reflectivity on radar in both of the supercooled cloud layer and the warm cloud and rain layer, and be more quickly in reaching the maximum value than the non-operated clouds which are under the similar conditions, and lasting a more longer period. After the cloud seeding, the maximum enhancement rate of the echo reflectivity in the low and warm region may be 200% and 100% respectively.
