abstract = "In this study, we present a methodology to study the properties of
convective precipitation in a holistic way. We apply a tracking
algorithm to X\‐band radar retrievals to store Lagrangian
properties of convective rain cells. The height of maximum
reflectivity (HZmax) is combined with the vertically integrated
water (VIW) to provide a useful parameter space to constrain the
microphysical study of the cells. This parameter determines most
of the shape of the vertical structure of rain cells, where VIW
acts as a modulating factor. Decreases in HZmax are likely
associated to enhanced collection processes, which favor growth of
reflectivity (Z), differential reflectivity (Zdr), differential
attenuation (Kdp), and droplet mean volume diameter (D0). This
growth is further favored under higher VIW conditions. By
discriminating the microphysical analysis by HZmax and VIW,
droplet growth can be analyzed in different types of rain cells
and stages of life cycle. Overall, the results presented here can
help understand the constraints of the vertical structure of rain
cells and microphysical properties from the combination of HZmax
and VIW. Contrary to the microphysical retrievals themselves,
computations of HZmax and VIW do not depend on dual
polarization.",
