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

Table 2

List of Guerrilla-heavy rainfall events used for vorticity evaluation. This includes occurrence date, time of first echo detection, first time of detection of vorticity greater than or equal to 0.03 s⁻¹, and time and maximum rainfall intensity on the ground.
