Lightning activity over large cities located in mountainous tropical zone and its relationship with particulate matter PM ₁₀ distribution. Bogotá City Case. Rev.fac.ing.univ. Antioquia [online]. 2017, n.82, pp.22-30. ISSN 0120-6230.  https://doi.org/10.17533/udea.redin.n82a03.

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 (2007-2012), 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 (PM10) 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.

Palabras clave : Lightning activity; pollution; PM10; urban heat island.
