The Global atmospheric Electric Circuit (GEC) is a fundamental coupling network of the climate system connecting electrically disturbed weather regions with fair across planet. GEC sustains electric field (or potential gradient, PG) which present globally and can be measured routinely at surface using durable instrumentation such as modern mills, are now widely deployed internationally. In contrast to lightning or magnetic fields, PG cannot remotely. Despite existence many datasets (both...
The water disponibility of Lake Titicaca is important for local ecosystems, domestic water, industry, fishing, agriculture, and tourism in Peru Bolivia. However, the level variability (LTWL) still needs to be understood. fluctuations LTWL during 1921–2018 period are investigated using continuous wavelet techniques on high- low-pass filters monthly time series, ERA-20C reanalysis, sea surface temperature (SST), level. We also built multiple linear regression (MLR) models based SST indices...
Abstract Solar phenomena such as flares and solar energetic particles events are potential candidates to affect the global atmospheric electric circuit. One can study these effects using measurements of field in fair weather regions. In this paper, we investigate deviations daily curve during disturbances (solar proton events) from mean values obtained conditions. Using superposed epoch analysis, order enhance visualization small effects, data observed between January 2010 December 2015 at...
Abstract The suppression of high‐energy cosmic rays, known as Forbush decreases (FDs), represents a promising factor in influencing the global electric circuit (GEC) system. Researchers have delved into these effects by examining variations, often disruptive, potential gradient (PG) ground‐based measurements taken fair weather regions. In this paper, we aim to investigate deviations observed diurnal curve PG, compared mean values derived from conditions, during both mild and strong...
Analysis of the variation potential gradient (PG) at ground level is important to monitor global electric circuit and different solar geophysical phenomena affecting it. However, this challenging since several local factors (e.g., meteorological) produce perturbations in gradient. Time series spectral analysis PG stations can help minimise effects so that may be more clearly observed. In work, for first time we performed recorded sites located Vostok, Concordia, Halley Casleo (Southern...
Abstract The decadal variability in summer precipitation over the Central Andes (10°–30°S) is investigated from 1921 to 2010 using low‐pass filtered time series of central and eastern El Niño–Southern Oscillation (ENSO) Pacific (C E) indices, South Convergence Zone (SPCZ) index, Atlantic SST Multidecadal (AMO) North (NAO) ERA‐20C reanalysis. Additionally, an empirical‐statistical downscaling (ESD) model was built. A rotated empirical orthogonal function (REOF) analysis shows that first...
Abstract High‐energetic charged particles, such as solar protons, and phenomena Forbush decreases are eligible candidates to affect the global electric circuit. These effects have been studied by analyzing disturbances of potential gradient in ground‐based measurements fair weather regions. In this paper, we investigate deviations diurnal curve, during proton events, decreases, from mean values obtained conditions. each situation, select only events which not accompanied or followed other....
Previous research has shown that the study of global electrical circuit can be relevant to climate change studies, and this done through measurements potential gradient near surface in fair weather conditions. However, highly variable due different local effects (e.g., pollution, convective processes). In order try minimize these effects, performed at remote locations where anthropogenic influences are small. work we present from five stations high latitudes Southern Northern Hemisphere....
Abstract. The ground-level atmospheric potential gradient (PG) has been measured with a radioactive collector method in Stanisław Kalinowski Geophysical Observatory Świder (52.12° N, 21.23° E), Poland, for several decades. Long-term measurements analysed previously revealed rather typical behaviour the diurnal and seasonal variations of PG land station controlled by pollution. Observation at such usually show maximum local winter months which are mostly affected anthropogenic 1965–2005...
