STRIKE FINDER
Long Range View
In the 100 and 200 nm views, the Strike Finder system will plot one strike
dot on the display for each lightning strike detected. If Strike Finder detects
increased lightning activity in the same area, the number of
displayed will increase in number and start to form
(clusters). One-to-three dots warn about hazards in developing conditions,
although a dozen or more are typical. These
an increased lightning activity. As these cells grow in size, and become more
defined, more avoidance margin should be accorded.
Short Range View
In the 25 or 50 nm range view, Strike Finder plots each lightning strike as
four dots. This accentuates the displayed data so as to draw more attention
to it at short ranges. This is apparent when zooming from 200 or 100 nm
to the 50 or 25 nm —one dot becomes four dots. Likewise, a small cell
becomes a much larger cell. Typically, if a cell in the 200 nm range view has
4 dots it will have 16 dots after you zoom to the 25 or 50 nm range view.

Strike Finder system displays them in an enhanced manner. For example,
when zoomed to 50 or 25 nm range view, a single dot will transform to four
dots. Similarly, a small cluster will increase its number of dots by a factor
of four, and become a much larger cluster, which is easier to see.
