Tops And Bases

The radar set can determine tops and bases of clouds. These echo tops and bases will be included

on the Radar Summary Chart whenever they are available. Echo tops and bases are indicated by

the format in Figure 2-9.

Intensity Levels

The levels of precipitation intensity determined by the Vertical Integrator Processor (VIP) range in

value from 1 to 6 and are shown graphically by a set of up to three lines enclosing concentric

shaded areas, where the middle areas have higher intensities (Figure 2-10).
