Early Detection of Baby-Rain-Cell Aloft in a Severe Storm and Risk Projection for Urban Flash Flood

<div>Schematic figures of formation of a vertical vortex tube. Circular arrows show circulations of horizontal vortex tube. (a) The vertical shear of horizontal wind generates a horizontally oriented vortex tube. (b) Updraft tilts a horizontal vortex tube into a vertical one (reproduced based on [<a href="/journals/amete/2017/5962356/#B15">15</a>–<a href="/journals/amete/2017/5962356/#B17">17</a>]).</div>
