Relationships were established between lightning location data and surface hourly observations of thunderstorms for 132 stations in the northeastern United States. The relationships are based on statistics derived from 2×2 contingency tables that were constructed for each station from a two-year sample of data for the 1985-86 warm seasons. To construct the tables, ground strike totals for the valid period of the hourly observations were accumulated for circular regions of varying radius (8-80 km) centered at each station. For the entire sample, the fraction of observer reported thunderstorms that were also recorded by the lightning network was found to increase rapidly from 0.44 within a 16 km radius to 0.82 at 50 km, beyond which the rate of increase was much smaller with a maximum of 0.89 at 80 km. Values over 0.9 at 50 km were, however, typical for stations located well within the interior of the network. -from Authors
