The Physics of Falling Raindrops in Diverse Planetary Atmospheres

18 Feb 2021 Kaitlyn Loftus Robin Wordsworth

The evolution of a single raindrop falling below a cloud is governed by fluid dynamics and thermodynamics fundamentally transferable to planetary atmospheres beyond modern Earth's. Here, we show how three properties that characterize falling raindrops -- raindrop shape, terminal velocity, and evaporation rate -- can be calculated as a function of raindrop size in any planetary atmosphere...
