stroke on a background map, only the Raw Lightning Data
window allows you to see fine detail a storm’s structure, such
as the prevalence of CG versus IC strokes, and their relative
amplitudes.
The data in the Raw Lightning Data window has been
processed only enough to determine its strength and
direction. Stronger flashes (they aren’t necessarily nearer
flashes) are displayed closer to the center of the window.
Flashes to the north are displayed towards the top of the
window (but only if your antenna is aligned properly); flashes
to the south are displayed towards the bottom of the window,
and so on. (The alignment of the antenna may be changed in
the Hardware Settings dialog.)
In stroke mode, every stroke will be displayed the instant it is
detected. But in flash mode, only those flashes that are
determined to not be reflections will be displayed. (The
aggressiveness of the reflection determination may be
changed by choosing Options | Reflection rejection from
the main menu.) The selection of flash mode or stroke mode
is available only when using one of the “classic” window
arrangements. The display of flashes is the default when
using the “simple” or “advanced” window arrangements.
In advanced mode (choose Window | Arrange | Advanced
from the main menu), you may choose between the display of
flashes or raw strokes. To do this, right-click in the window
and choose Raw Lightning Data Properties | Settings |
View from the popup menu. You can choose between
viewing strokes and flashes in the Settings Dialog.
One of the hallmarks of a nearby storm as it appears in this
window is a “tail” of stronger strokes. Because stronger
strokes are plotted closer to the center of the window, these
“tails” will point towards the center of the screen.
More distant storms won’t exhibit this feature. They are
characterized by a cluster of strokes further from the center
of the screen.
