By using radar data of Longyan CINRAD/SA from 2003 to 2007, the mesocyclone products were statistically analyzed.The characteristics of mesocyclones determined by person and the persistent three volume scannings and corresponding storm are mainly analyzed. The analysis shows that the mesocyclone which has more than three volumes scanings is well related with strong weather phenomena such as hail,thunderstorm, shorttime strong rainfall and so on. Based on the analysis of the typical strong weather processes, we can conclude the variation rules of the mesocyclone height and the largest shear’s height, and the correspondence relationship among the shear, the strong or weak mesocyclone and different types of strong weather. Therefore, the above conclusins will provide references for forecasters to predict shorttime strong rainfall, hail, thunderstorm timely and accurately.
