STRIKE FINDER

Cell Stretch

All spheric displays have the property of
dots from a storm cell in a radial direction, (see Figure 28). This
phenomenon occurs when mapping strong disturbances. The
simultaneously trail outward and inward away from a storm
caused when multiple strikes of varying degrees of strength are detected
within the same storm cell and plotted in a linear pattern according to their
intensity. The amount of cell stretch is dependent upon the severity of the
storm—the more severe, the more cell stretch. Nonetheless, sufficient
'normal' strikes will occur for detection of the storm center.

location of the lightning activity. Strike Finder uses elaborate lightning
positioning algorithms to alleviate cell stretch. This process reduces the cell
stretch pattern, and by that, greatly improves interpretation of storm cell
location.
Strike Finder should not exhibit significant cell stretch with every storm. If
this occurs, suspect interference from another electronic device on-board
the aircraft. (see Appendix A, Troubleshooting, p.51).
