“…The results are in agreement with the global diurnal lightning variation (Blakeslee et al, 2014;Pan et al, 2013). In contrast, the diurnal distribution of lightning activity over the sea is smooth and the maximum electrical activity occurs in the morning.…”

“…Analysis of the seasonal climatologies (Fig. 2) clearly indicates that most locations have higher lightning activity over land than over ocean regions and that lighting is predominantly a warm season phenomena in the Australian region, broadly consistent with previous studies of seasonal and temporal variations in lighting activity globally and in the Australian region (Christian et al 2003;Kuleshov 2004;Blakeslee et al 2012;Kuleshov 2012).…”

A climatology of lightning ground flash density is examined for the Australian region based on 18 years of data. The dataset and methodology used are consistent with that of a previous study based on eight years of data. Lightning flash densities are obtained from two satellite instruments-the Lightning Imaging Sensor and the Optical Transient Detector. A climatological map of lightning ground flash density is produced, covering the Australian region, representing the most comprehensive map of its type to date. For the first time, we present (i) maps detailing the seasonal variability of the lightning ground flash densities and (ii) examinations for the maritime regions surrounding the Australian continent as well as for land regions. A notable feature of the climatology is that a maximum in lightning activity during the cooler months occurs over the ocean to the east of the continent. The period of data available for this study is over twice as long as for the previous study, thereby allowing a significant update to the climatology. Results of this study are intended for use in relation to hazards associated with lightning occurrence and applications such as lightning safety standards.

“…The lower observed activity in the morning hours is inherent to the reduced occurrence of convective development due to solar heating of the ground and/or the atmospheric boundary layer. The overall diurnal behavior of CG flash counts in Europe overlaps well with those in other parts of the globe (Blakeslee et al, 2014). Figure 2d displays the mean polarity distribution in Europe as a function of month.…”

Abstract. Cloud-to-ground (CG) lightning data from the European Cooperation for Lightning Detection (EUCLID) network over the period 2006-2014 are explored. Mean CG flash densities vary over the European continent, with the highest density of about 6 km −2 yr −1 found at the intersection of the borders between Austria, Italy and Slovenia. The majority of lightning activity takes place between May and September, accounting for 85 % of the total observed CG activity. Furthermore, the thunderstorm season reaches its highest activity in July, while the diurnal cycle peaks around 15:00 UTC. A difference between CG flashes over land and sea becomes apparent when looking at the peak current estimates. It is found that flashes with higher peak currents occur in greater proportion over sea than over land.
