ABSTRACT
The relationship between cloud-to-ground (CG) lightning and convective precipitation over the Iberian Peninsula during the warm season was analyzed. The database covered the period between 1992 and 1994 and the precipitation data from 68 meteorological observatories were used. Temporal and spatial scales of 1 month and 10^sup 2^ km^sup 2^ were considered. Values of rain yield (defined as the ratio of convective precipitation to CG flash count over a common area) were centered around a mean value of ~10^sup 2^ kilograms per flash (kg fl^sup -1^) but varied as a function of the climate regime, increasing from a mean value of 1.2 X 10^sup 8^ kg fl^sup -1^ for the semiarid region of ...
