| Zusammenfassung |
The electrodynamic
properties of intense oceanic lightning discharges are compared to intense
continental lightning discharges. Particularly intense negative lightning
discharges with absolute charge moments > 2 kC · km occur more often
over the oceans than over the continents during April 1998. Intense continental
lightning discharges, with negative and positive polarity, and intense positive
oceanic lightning discharges primarily occur associated with mesoscale
convection in the late evening. The number of intense negative oceanic
lightning discharges increases in the early morning hours, probably associated
with the resurgence of oceanic mesoscale convection in coastal areas. The
day-to-day variability of intense negative oceanic lightning discharges
exhibits a five day periodicity, possibly related to planetary waves.
