The results show that: (1) the degree of riming and the 0180 value of the ice particles correlate
positively for six of the six storms sampled, except at times .of strong convective activity;
(2) temperatures of ice phase initiation do not agree with the isotopically derived "temperatures" of the
precipitation reaching the ground, as a result of riming; hence, the amount and location of supercooled
liquid water in the clouds are considered to be strong determining factors influencing the 0180 values:
and (3) no obvious correlations were observed between precipitation rate and 0180 or between the
maximum precipitation intensity and the range of the 0180 values of the snowfall.

rain volumes over areas. Journal of Applied Meteorology, 27:491-502.

Digital radar data from the North Dakota Cloud Modification Project (NDCMP)-the 1981 and 1982
summer experiments-are used to further investigate the relationship between convective rain volumes
and area-time-integrals (A TI). The A TI technique provides a means of estimating total rain volumes
using areas covered by rain events (for reflectivities :2: 25 dBZ) integrated over the cluster duration.
