SECTION 2
STORMSCOPE INTERFACE
DISPLAYING STORM DATA ON THE MAP PAGE
The Map Page (Figure 2-3) displays cell or strike
information using yellow lightning strike symbology
overlaid on a moving map. This added capability improves
situational awareness, which in turn makes it much easier
for the pilot to relate storm activity to airports, navaids,
obstacles and other ground references.
Storm Activity
Figure 2-3 Storm Data on Map Page
NOTE: Storm data is displayed on the Map Page
only if aircraft heading is available.
In normal operation, the current mode and rate are
displayed in the top right-hand corner of the Map Page.
The mode is indicated by the word "STRIKE" when in
strike mode, or "CELL" when in cell mode.
Strike mode indicates the approximate location of
lightning strikes. Only the data that is viewable on the
screen is included in the strike rate.
Cell mode uses a clustering program to identify clusters
of electrical activity that indicate cells. Cell mode is most
useful during periods of heavy storm activity. Displaying
cell data during these periods frees the user from sifting
through a screen full of discharge points and helps to
better determine where the storm cells are located.
