Lightning activity over large cities located in mountainous tropical zone and its relationship with particulate matter PM10 distribution. Bogotá City Case

Abstract

ABSTRACT:This paper presents an analysis on the influence of anthropogenic phenomena over the lightning activity in large cities located in mountainous region of tropical zone, specifically in Bogotá City. Some preliminary results show an increase of lightning activity between 33% and 340% for the period under study (2007)(2008)(2009)(2010)(2011)(2012), when a comparison between urban and rural adjacent zone is carried out. An additional analysis of the influence of pollution on lightning activity was also carried out; this analysis shows that there is a tendency of correlation between number of strokes and particulate matter (PM 10 ) for the zones under study with the highest levels of contamination of the city. In order to achieve the goals of this study, data from one of the Colombian Lightning Location Systems (SID) and the monitoring network of air quality of Bogotá were used. The results are consistent with other studies carried out in different cities of the world. RESUMEN:El siguiente estudio realiza un análisis sobre la influencia de fenómenos antropogénicos en la actividad de rayos para la ciudad de Bogotá. Los resultados muestran que hay un incremento en la actividad de rayos entre el 33%-340% para el periodo de 2007-2012, cuando se compara la zona urbana de Bogotá con una zona rural adyacente. También se realizó un análisis para observar la influencia de la polución de la ciudad, sobre los rayos. Los resultados muestran que hay una tendencia entre el número de rayos y el material particulado para las zonas con mayores niveles de contaminación de la ciudad. Para realizar el estudio fueron utilizados los datos de la red de localización de rayos -SID y para la información de niveles de polución se utiliza la red de monitoreo de calidad del aire de Bogotá. Los resultados son consistentes con otros estudios llevados a cabo en otras ciudades del mundo.

A Systematic Review of the Potential Influence of Urbanization on the Regional Thunderstorm Process and Lightning Activity

“…Scholars have conducted comprehensive research on the influence of aerosols on lightning activity, exploring the intricate relationship between these atmospheric components and their role in modulating lightning occurrence [11,32,43,[73][74][75][76][77][78][79][80]. Soriano and de Pablo [43] utilized lightning detection data to analyze the lightning activities in various Spanish cities and found that higher concentrations of SO 2 correlate with an increase in CG flashes.…”

Use of the Speed of Sound for Heights Below the Troposphere in Colombia to Determine the Distance of Lightning Strikes

“…Colombia is a country located in the tropical zone (Del-Rio, Younes, & Pulgarín, 2017), and its altitudes range from sea level and its highest point at 5775 meters (Stančík, 2003). Colombia has 39 meteorological stations located in different places of the country (Instituto de Hidrología, Meteorología y Estudios Ambientales), which belong to the IDEAM(acronym in Spanish for Institute of hydrology, meteorology, and environmental studies), who is responsible of managing the data of climate in Colombia.…”
