Electricity of the Convective Atmospheric Boundary Layer: Field Observations and Numerical Simulation

The Atmospheric Electric Field under Fair-Weather Conditions in the South of Western Siberia based on Observations in Tomsk in 2006–2020

“…Figure 4 demonstrates that, in addition to the prominent main maximum and minimum of diurnal φ, the secondary maximum and minimum of diurnal φ caused by the convective generator [6,7,18] may also be seen in different months. Their manifestation is timed to coincide with the sunrise and varies greatly from summer to winter.…”

“…Improvements to existing instrumentation contributed to the organization of global systematic observations of electrical quantities such as the potential gradient (φ), electrical conductivity of air, ion concentration, current density, and others [1][2][3][4][5][6][7][8]. Today, numerous ground-based measurements provide information about the electrical state of the atmosphere,and different approaches [1,6,9] to data selection and processing have allowed us to draw fundamental conclusions about the influence of fair-weather and disturbed weather conditions [6,[11][12][13][14][15][16][17][18][19][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] on the surface atmospheric electricity.…”

Электрическое Поле Невозмущённой Атмосферы В Томске

“…Осреднѐнная суточная вариация градиента потенциала электрического поля, широко известная как кривая Карнеги или унитарная вариация, которая соответствует универсальному времени и не зависит от места измерения, и представляет собой глобальный ежедневный вклад электрической активности в районах нарушенной погоды [1]. Однако, вклад региональных и локальных факторов может существенно влиять на суточные вариации приземного электрического поля в различных регионах земного шара [2][3][4].…”
