Abstract
By using the Doppler radar echo about Base Reflectivity(R),Storm Relative Vel Map(SRM),Vert Integrated Liquid(VIL)etc,a severe hail and wind weather process which occured in the south of North China on June 20,2004 is analyzed.The result shows that the hail and severe wind weather process was mainly caused by mesoscale cyclone in supercell storm echo.The reason that the process lasts so long is the development of finger echoes and supercell storm echoes.
A significance statement is not available in the OpenAlex record.
