Vertical columns of enhanced ZDR above the environmental freezing level can be used as proxies for updrafts, so creating a two-dimensional field of ZDR column locations can focus the latent heating forcing to where convective updrafts are actively occurring. This presentation will discuss the algorithm used to detect ZDR columns and subjectively assess how well the analyzed ZDR columns match the expected locations of updrafts in convective events. The method used to create a temperature tendency field from ZDR column locations that can be assimilated into the HRRR will also be discussed. These ZDR column-derived temperature tendency fields will then be compared to the temperature tendency fields currently used by the HRRR that are derived from radar reflectivity in order to demonstrate the feasibility of assimilating ZDR columns instead of or in addition to radar reflectivity. Preliminary results from a case study in which ZDR column information is assimilated may also be presented.
