By using the NCEP reanalysed data,the conventional observation data and Doppler radar data of the synoptic and mesoscale characteristics of two strong convective weather in Hexi Corridor are analyzed.The results show that they are differ greatly from each other on the circulation and mesoscale system.A right-moving squall-line(cyclone) led to the hail on 7 July 2006.In contrast,a stong left-moving(anticyclone) supercell brought on the hail on 10 August 2006.The value of storm-relative helicity(SRH) for right-moving squall-line is positive in the 0-3km layer,while the value of storm-relative helicity(SRH) for left-moving supercell is negative during development.
