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

Figure 8

The statistics of the elapsed time since the first echo of a rain-cell was detected: (a) green bars: the time interval between the vorticity detection and the first radar echo detection; orange bars: the time interval between the maximum rainfall intensity observation and the first echo detection; (b) blue bars: the time interval between the maximum rainfall intensity observation and the vorticity detection.
