RANDOMLY SCATTERED DISCHARGE POINTS

Atmospheric instability associated with cumulus clouds, or
developing or dissipating thunderstorms could cause randomly
scattered discharge points as shown in figure 4-9. Random
discharge points are more likely to appear in the strike display
mode than in the cell display mode due to the cell display mode's
clustering algorithm. If you observe random discharge points,
continue to monitor the screen for developing clusters which
indicate thunderstorm activity.

Figure 4-9. Randomly Scattered Discharge Points
CLUSTER & SPLATTERING WITHIN 25 NMI
Figure 4-10 shows the 360° weather view at the 25 nmi range. One
moderately active thunderstorm appears as a cluster of discharge
points at 8:30 centered 14 nmi away with a splattering of discharge
points throughout the 25 nmi range. Such splattering is due to
electrical discharges within 3 to 5 nmi of the aircraft and indicates
that the aircraft is too close to the thunderstorm.
