Based on EOS/MODIS multi-channel remote sensing data,the characteristics of a strong convective cloud were analysed qualitatively according to a heavy rainfall in the northern of Anhui province from 30, June to 1,July in 2006.

The hailstorm occurred on July 6 to 8,2003 over the northeast of Qinghai-Xizang plateau was simulated by using MM5,and its meso-scale circulation background and local convective cells characteristics were analyzed based on simulated data.

The results show that (1) MM5 is good to simulating this hailfall process, (2) Warm humid air from south at lower level and cold dry air from northwest at middle and upper level and local terrestrial factors were important, (3) Convective cells formed at high altitude plots firstly and then spread to lower altitude, (4) .

Analysis of convective clouds characteristic in Ningxia;

,the characteristics of parameters and evolutive regularities of convective cloud in the mid-mountain region of southern Urumqi were analyzed in this study,including the echo top,and its intensity,occurrent periods,nat.

It is very meaningful to separate the precipitation cloud system into convective cloud and stratiform cloud.

The convection cloud is the main precipitation system in south China,having abundant water resource.

For researching the rule of convection cloud in Jianghuai area, we used Dual-doppler Radar in the experiment of weather modification about convection cloud.
