Journal of Financial Research, EarlyView.Abstract This article examines how salient sustainability risks from near‐miss natural disasters influence board composition. Using a difference‐in‐differences design, I find that firms located in counties neighboring disaster‐affected areas significantly increase the presence of directors with sustainability expertise following the disaster.

Are large high-altitude electric fields caused by global thunderstorms? [PDF]
Earth, Planets and Space, 2014 Using the model of a spherical symmetric atmosphere the large-scale electric fields generated by the global thunderstorms are investigated. Theoretical formulations have been developed to calculate high-altitude electric fields due to global thunderstorms, taking into account the presence of the ionosphere.

Optically perceptible characteristics of sprites observed in Central Europe in 2007–2009
, 2013 Sprites are luminous optical emissions accompanying electric discharges in the mesosphere. 489 sprite events have been observed with a TV frame rate video system in Central Europe from Sopron (47.68 °N, 16.58 °E, ~230m MSL), Hungary between 2007 and 2009.

Observations of Electric Fields Sounding in the Mature Stage of a Thunderstorm
Geoscience Data Journal, Volume 13, Issue 3, July 2026.Successive electric field soundings separated by only 6 min provided a rare view of charge structure of a mature thunderstorm. The observations reveal horizontally inhomogeneous charge regions, an unusually deep upper negative layer, and charge features that cannot be readily explained by current thunderstorm electrification mechanisms. ABSTRACT In the

International Journal of Satellite Communications and Networking, Volume 44, Issue 4, Page 357-367, July/August 2026.ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity
