Modeling the Flash Rate of Thunderstorms. Part I: Framework

Abstract: In this study a straightforward theoretical approach to determining the flash rate in thunderstorms is presented. A two-plate capacitor represents the basic dipole charge structure of a thunderstorm, which is charged by the generator current and discharged by lightning. If the geometry of the capacitor plates, the generator-current density, and the lightning charge are known, and if charging and discharging are in equilibrium, then the flash rate is uniquely determined.To diagnose the flash rate of real-world … Show more

“…The reported LINET "strokes" are grouped into "flashes" before the comparison with simulated flashes. For this purpose all events recorded by LINET that occur within 1 s and in an area with a radius of 10 km are binned into a single flash (Dahl et al, 2011b). The sensitivity of the results for a different choice of the binning parameters (5 km and 0.5 s) is shown in Sect.…”

“…Those parameterization functions have been applied to parameterize flash rates in models, where convection cannot be resolved. As it is discussed in detail in Dahl et al (2011), all these "single-parameter" approaches, which derive flash rates from only one other storm parameter, simply cannot be capable of reproducing the electrical development of an individual storm correctly. Since there is strong evidence that close correlations exist, they still seem to be feasible methods to obtain general guesses for flash rates.…”

“…There has been growing public concern in recent years in the forecasting and assessment of the intensity of convective storms around the world based on lightning (e.g., MacGorman and Burgess 1994;Lang and Rutledge 2002;Carey et al 2003). Previous researchers have developed several empirical relationships between lightning and convective parameters, such as cloud-top height (Price and Rind 1992;Boccippio et al 2002;Barthe et al 2010;Dahl et al 2011;Basarab et al 2015), upward ice mass flux (Allen and Pickering 2002;Deierling et al 2008;Finney et al 2014), convective precipitation rate (Meijer et al 2001), and updraft characteristics (Wiens 2005;Deierling and Petersen 2008). For example, Deierling and Petersen (2008) found that the total flash rate is highly related to the updraft volume with vertical velocity greater than 5 m s 21 as well as greater than 10 m s 21 .…”
