“…A very pronounced daily cycle is also detected, with an apparent preference for mid-afternoon lightning activity. The same result was achieved by in Spain, Pineda et al (2007) for the northwestern Mediterranean region, Farias et al (2009) for the metropolitan region of São Paulo (Brazil) and Hyun et al (2009) for South Korea.…”

An analysis of the cloud-to-ground discharges (CGD) over Portugal is carried out using data collected by a network of sensors maintained by the Portuguese Meteorological Institute for 2003–2009 (7 yr). Only cloud-to-ground flashes are considered and negative polarity CGD are largely dominant. The total number of discharges reveals a considerable interannual variability and a large irregularity in their distribution throughout the year. However, it is shown that a large number of discharges occur in the May–September period (71%), with a bimodal distribution that peaks in May and September, with most of the lightning activity recorded in the afternoon (from 16:00 to 18:00 UTC). In spring and autumn the lightning activity tends to be scattered throughout the country, whereas in summer it tends to be more concentrated over northeastern Portugal. Winter generally presents low lightning activity. Furthermore, two significant couplings between the monthly number of days with discharges and the large-scale atmospheric circulation are isolated: a regional forcing, predominantly in summer, and a remote forcing. In fact, the identification of daily lightning regimes revealed three important atmospheric conditions for triggering lightning activity: regional cut-off lows, cold troughs induced by remote low pressure systems and summertime regional low pressures at low-tropospheric levels combined with a mid-tropospheric cold trough

“…In conformity with the findings of Hyun et al . () the strongest diurnal signals were observed in the central part of South Korea, which also experiences substantially higher number of thunderstorms in comparison to the rest of the country. Similar role of topography on the moist onshore blowing air leading to strong diurnal strength of lightning activity was also observed in Southeast Asia, mainly Thailand and along the Arakan Yoma ranges in Myanmar.…”

“…Furthermore, the close relationship between peak time of lightning activity and peak time of precipitation events have been the focus of several published literature (Liu and Zipser, 2008; Hyun et al ., ). Overall, a phase‐wise progression was observed for most of the tropics with varying lag time from the analysis of TRMM data by Liu and Zipser (2008).…”

“…Recently, with the availability of satellite‐based high‐temporal resolution lightning data, such as the Tropical Rainfall Measuring Mission (TRMM) dataset, it is now possible to examine diurnal patterns of lightning strikes in less explored regions of the tropics. A few regional‐level studies examining lightning patterns include South Korea (Hyun et al ., ), Chongqing, China (Li et al ., ), and eastern Tibetan plateau (Xu and Zipser, ), as well as for the entire tropics (Liu and Zipser, ). In case of South Korea, lightning data from station level observations revealed predominantly night‐time lightning strikes in the south, while an afternoon peak was observed in the midland areas (Hyun et al ., ).…”

Diurnal variations in summertime lightning activity in Tropical Asia

Many meteorological phenomena exhibit distinctive diurnal variations that vary substantially from place to place. In this investigation, we use Tropical Rainfall Measuring Mission data to assess spatial patterns in the diurnal variations of summertime lightning activity throughout tropical Asia. Harmonic analysis of the dataset reveals strong diurnal patterns in lightning activity with most locations exhibiting an afternoon maximum and a late-night, early morning minimum. Notable exceptions include the eastern coastal areas of the Indian subcontinent and China, with the peak activity occurring in the early evening hours. We generally find that the diurnal patterns are related to orographic interactions as well as the seasonal wind circulation of onshore winds along the coastal areas. The strength of the cycle was relatively stronger in the interior of the continent particularly over northwestern India and the Tibetan plateau.

Evaluating a simple proxy for climatic cloud‐to‐ground lightning in Sichuan Province with complex terrain, Southwest China

Lightning matters to human life and natural fires so much that monitoring and predicting lightning are highly important. A simple proxy for climatic cloud-to-ground (CG) density is evaluated defined as the product of convective available potential energy (CAPE) and precipitation rate using data from 2005 to 2017 in Sichuan of Southwest China. CAPE times precipitation rate (CP) relates the monthly distribution and magnitude of negative lightning in the basin region more closely, while CP describes the monthly distribution and magnitude of positive lightning in the plateau region more appropriately.Except for individual years, the annual variation trend and magnitude of CP and positive and negative lightning are relatively consistent in the basin region, while the description of the annual variation trend and magnitude of lightning by CP in the plateau region is insufficient, especially for negative lightning. CP represents the high-value areas of the positive and negative lightning in the basin and southern Sichuan reasonably, but misses the lightning belt in the plateau region. In general, the performance of CP for lightning in the basin is superior to that in the plateau, this may be caused by two factors, one is the particularity and complexity of lightning in the plateau resulted from special topographic and meteorological conditions, the other one is the limitation of CP caused by the fact that CP does not take into account other environmental factors contributing to lightning. The ability of this simple proxy to describe CG lightning in Sichuan is limited by vertical wind shear in the middle and lower troposphere, zero degree height, and liquid water path, mainly because the proxy does not have the ability to generalize these factors that play a key role in lightning activity.
