LIGHTNING DETECTION ANDTRACKING SYSTEM (LDATS)
The LDATS is a microprocessor-based systemthat displays the location of real-time or time-delayed lightning occurrences. Presentations are by way of a high-resolution color monitor (television) and/or an X, Y, or color dot matrix printer. The theory and operation of LDATS will be discussed in more detail in volume 2 of this rate training manual.
The area covered by this system is displayed in map form on the color monitor or printer. The scale can be adjusted up or down by the use of a variable zoom feature. Figure 10-4-5 illustrates a typical base viewing area, while figure 10-4-6

shows a scaled-up map. Lightning strikes aredisplayed/plotted within a fraction of a second of their occurrence. Each stroke appears as a dot on the monitor and/or printer. A color-coding feature of the system changes the color of displayed strokes at 10-minute intervals. This per-mits the monitoring and tracking of the light-ningís associated thunderstorm. It also allows you to gauge a thunderstormís intensity level. An in-crease in the number of electrical discharges displayed signifies an increase in intensity, while a decrease in the number of strokes displayed over a period of time indicates a lessening of storm strength.
