“…The number of intense negative oceanic lightning discharges increases in the early morning hours, probably associated with a resurgence of oceanic mesoscale convection in coastal areas, initiated by radiative cooling or an offshore land breeze. The observed five day periodicity of intense negative oceanic lightning discharges is possibly associated with planetary waves (Harth, 1982), which may modulate the number of observed lightning discharges. It may be argued that the globally triangulated lightning discharge location accuracy of ∼ 1 Mm (Füllekrug and Reising, 1998;Füllekrug and Constable, 2000) may influence the statistical analysis.…”

Abstract. 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.Key words.

“…Long term variability of thunderstorm activity has been reported in the literature, and it is believed to result from planetary waves [Harth, 1982] [Abbas, 1968;Bliokh et al, 1980;Sentman, 1995] but little experimental evidence for this interference has been reported.…”

The Stanford ELF/VLF Radio Noise Survey provides digital time series in the ELF range and VLF analog recordings of one horizontal magnetic field component at different locations around the globe. Three sites, Arrival Heights in Antarctica, Søndrestrømfjord in Greenland and Stanford in California, are chosen to investigate the natural magnetic noise in the frequency range of the Earth‐ionosphere cavity resonances (6–60 Hz). The resonances are interpreted as pure resonance phenomena and the associated parameters are derived in a robust manner by use of the complex exponential algorithm. The resulting amplitudes of the first and second resonances exhibit a pronounced diurnal variation and a distinct day to day variability of the same order during the time interval from January to April 1990. The day to day variability is well correlated between all of the three different sites. They also exhibit a 20–30 day variation that is related to the solar rotation period, expressed by means of sunspot numbers.
