Environmental aerosols and their effect on the Earth?s local fair-weather electric field

Preliminary findings of surface fair-weather electric field trends over small tropical island station, Suva, Fiji

“…Our measurements were over land hence may be a slight increase in the average PG value. Jayaratne and Verma (2004) showed that the Earth's fair weather electric field increases with an increase in the aerosol particles concentration in the environment. In the bimodal variation Israel (1973) noted that one of the modes coincides with the maximum global thunderstorm activity (~19 hrs UT) while the other occurs in the late afternoon local time.…”

“…The global electrical measurements are gaining renewed prominence since they are found to be a more effective and efficient means of monitoring global warming trends (Williams et al 2003). The surface potential gradient (PG) or electric field was found to be positively correlated to the aerosol number concentration (Jayaratne and Verma 2004). Surface PG measurements have often proved as the most frequently used (Anderson 1967) and reliable technique to study atmospheric electricity, be it global, regional or local (Latha 2003).…”

Coagulation and Condensation of Aerosols in Atmospheric Dispersion Model

“…Usually, when the earth's local weather is fine, the electric field is about 180 Vm −1 − 280 Vm −1 , depending on the concentration of aerosols [2]. When the aerosols are continuously deforming with relative motion resulting in particles colliding and coalescing to form larger particles where an electric field induces a dipole in uncharged aerosol particles [3,4,5] the charges induced on the closest sides of the neighbouring particles are of opposite sign.…”

Effect of Reaction Rate on Dispersion of Atmospheric Aerosols in the Presence of Electric Field

“…Further the electrical forces in thunderstorm also appear to be as important as the fluid forces at some stages of critical forces [2]. Besides the various electrical phenomena, it is found that different chemical compositions of aerosols take place nearearth's atmosphere [3]. Fluids with antisymmetric stress are known as polar fluids.…”
