Justification |
NOAA changed the names
of these measures to better reflect their origins in severe weather.
The name change did not impact the methodology used to calculate
the measures. The addition of “county-based” to the
tornado measures is to distinguish them from the storm-based measures
that will come online in FY 2009. |
