WebJan 22, 2024 · The newly formed ice crystals are then expected to grow first through vapor deposition and then more rapidly through riming of cloud droplets and aggregation with other ice particles. These much larger hydrometeors should be detectable by cloud and precipitation radar, since radar reflectivity is highly sensitive to particle size.
