14 times mesocyclone products of CINRAD/SA at Jinan in 2002 as well as several times of CINRAD/SC at Binzhou are analyzed. Two of the mesocyclones associated with a supercell storm and a minisupercell storm remained a long period, and accompanied with severe weather, such as hail, damage wind and so on. The others appeared in a short time, and were not always associated with severe weather depending on the strength of the mesocyclone as well as weather situation and the other products of radar.
