STUDY OF CINRAD/SA PRODUCTS FOR A HAIL STORM

The products of CINRAD/SA during the course of generation, development and motion of a hail-storm which occurred near Dong'e county in Shandong Province on September 27, 2002 are analyzed. The storm has the characteristics of supercell, such as a "V-notch", a boundary weak echo range (BWER) and a mesocyclone. Mesocyclone exists in the storm for almost 90 min. The speed of relative movement (SRM) in different slice can also display the procedure of the mesocyclone occurring, developing and dying out. The storm tracking information (STI), mesocyclone (M), hail index (HI) and vertical integrated liquid water (VIL) are valuable for identifying and forecasting the hail.
