A great deal of knowledge is available relating to thunderstorms and turbulence, and the RHIs portrayal of a thunderstorm provides a fairly com-plete picture of the associated turbulence, icing, and hail.

In an actively developing thunderstorm, the thundercloud builds to great heights. The higher the top of the storm, the more violent the storm and its associated turbulence. On the RHI, this convective buildup is reflected in a rapidly rising echo. When observed on the RHI, it signifies that the thunderstorm is most active and the turbulence most severe. When the convective activity decreases, and the storm begins to dissipate, the turbulence decreases. The RHI echo shows the storms decrease in altitude with time, and a bright band develops as the turbulence decreases.

Learning Objective: Recognize the capability of the lightning detection and tracking system and interpret its video and printer presentation.
