    Reflectivity measured by the MIT radar showing (a) a CAPPI at a height of 3 km and (b) a pseudo-RHI north–south cross sectionover the profiler site at 1840 LT 5 December 1989, while (c) and (d) are CAPPI and pseudo-RHI scans at 1940 LT. Reflectivities greaterthan 30 dBZ are shaded in (a), (b), and (d) to highlight regions of convection, while areas greater than 20 dBZ are shaded in (c) to delineatethe stratiform rain. Contours are drawn every 10 dBZ from 20 dBZ in (a) and (c) and from 10 dBZ in (b) and (d). The origin of the coordinatesystem marks the profiler site. Here, L1 marks the leading line of cells and L2 is the line of mature cells, while C1 is the leading cell passingover the profiler and C2 is the mature cell. The north–south dashed lines in (a) and (c) mark the positions of the pseudo-RHI scans.

    Time–height cross sections of the vertical motion detectedby the profiler showing the convective region (lower frame) and thestorm as a whole (upper frame). Contours are drawn every 5 m s 21ontheupperframe andevery 2 m s 21 in the lower frame. The upwardmotion is shaded. The heavy line in the lower panel denotes themaximum height at which rain echoes were visible. Here, C1 and C2are as in Fig. 4. The labels along the bottom mark the convective(C), transition (T), and stratiform (S) precipitation over the profiler.

    Time series of the vertical motions observed with the profiler. Each estimate is an averageover 94 s. Successive heights are offset by 10 m s 21 , and the dashed lines represent 61 m s 21 toshow the draft cores. Velocities with magnitudes greater than 1 m s 21 are shaded. A length scaleis shown in the top left as a reference to the approximate time corresponding to a length scale of5 km. Here, C1 and C2 are as in Fig. 5.

    Time–height cross section of total precipitating water (gm−3 ). Here, C, T, and S are as in Fig. 5. There are no data below thedashed line at a height of 1.35 km. The gap around the freezing levelis because the retrieval processes do not work for mixed-phase pre-cipitation.
