By using the data of grid-based vertically integrated liquid water(VIL)and cell-based VIL,which were observed by Binzhou SC radar in volume scan mode,vertical structures of several severe convective storms were studied.The results show that the two VIL products varied in-phase with storm evolution,and they were both well indicative for warning damage weather.Generally,cell-based VIL is larger than grid-based VIL,especially in the case of mature and isolated severe cell storms.The difference of the two VIL products may be used as the quantitative indicator of cell storm intensity.The limitation of volume scan mode possibly leads to the VIL distortion,due to the increase of VIL errors caused by the identification of centroid of multicell storm.
