A Drop is Not a Drip Way up high in the atmosphere, dust and smoke particles suspended in clouds create places where moisture can settle and form into drops. This new video from the Global Precipitation Measurement mission explains why. Three sets of radar data collected in different climatic regions are analyzed to evaluate whether there is a unique shape–size relation. Raindrops are actually shaped like the top of a hamburger bun, round on the top and flat on the bottom. By changing the initial axial ratio relation, a procedure of minimization between the two curves is developed to derive the underlying drop shape–size relation governing the radar measurements under consideration. An averaged curve of K dp / Z h versus Z dr is obtained and compared with the same curve obtained from the radar data. Raindrops start to form in a roughly spherical structure due to the surface tension of water. High in the atmosphere, water collects on dust and smoke particles in clouds. Using an initial drop shape and choosing a set of DSDs described by a normalized gamma model, polarimetric radar measurements are produced by simulation. ESS2.A Keywords: raindrops, precipitation microphysics, drop size Summary: This article teaches how a drop of rain changes shape as it falls through the atmosphere. To obtain information on the raindrop shape–size relation underlying a set of radar observations, this domain is studied in conjunction with another domain describing the relation between the drop axial ratio (or shape) and its equivolumetric diameter. Therefore, by analyzing the color, texture and shape characteristics of raindrops in images, we first identify possible raindrop candidates in the regions.

This procedure is obtained using a domain defined by the two variables K dp / Z h and Z dr where the drop size distribution (DSD) variability is collapsed onto a line and any variation is essentially due to the drop shape variability.

Baldini, LucaĪ method is proposed to retrieve raindrop shape–size relations from the radar measurements of reflectivity factor Z h, differential reflectivity Z dr, and specific differential phase K dp at S band.
