Abstract
Lightning data for the five-year period of 1996-2000 have been analyzed to understand the statistical features of lightning and the relationship between heavy rainfall and lightning frequency over the Korean peninsula. Analysis indicates that lightning occurs most frequently in July and August. And lightning occurs more frequently in the afternoon hours of 06 - 11 UTC (3 - 8 pm, Korean local time). Geographically, it occurs much more frequently over the western part of the peninsula near the west coast. Area of maximum rainfall amount does not coincide well with that of highest lightning frequency. It has been found that heavy rainfalls occur without any lightning at 68% of heavy rainfall stations during summer and at 82% of heavy rainfall stations for June. Rainfall amount does not show a systematic variation with lightning frequency. Band-type convection shows largest number of lightning among the heavy precipitation systems considered in this study, mainly due to its stationary behavior and sustained strength.
