Twelve years of continuous measurements of atmospheric electrical activity in México’s Tropical highland
Atmospheric electric activity measurements have been recorded continuously by a punctual lightning system at a tropical highland observatory from 1988 – onwards, and were analyzed to obtain lightning statistical confident results for thunderstorms occurrence on the leeward side of the southern mount...

COMO EJEMPLOS, SE MUESTRAN LOS PERFILES INDIVIDUALES DE LA ACTIVIDAD ELÉCTRICA ATMOSFÉRICA ASOCIADA CON TORMENTAS SEVERAS. LOS RESULTADOS DEJAN CLARO QUE SE REQUIERE DE LA SECUENCIA DE MEDIDAS ELÉCTRICAS LO MAS RÁPIDA POSIBLE PARA OBTENER DATOS SIGNIFICATIVOS Y APLICABLES EN RELACIÓN CON UNA SERIE COMPLETA DE TORMENTAS, CONSIDERANDO LA MEDIA DEL TIEMPO DE VARIACIÓN DE LAS MEDICIONES DE LA ACTIVIDAD ELÉCTRICA ATMOSFÉRICA A UNA ALTITUD DE 2,270 M S.N.M. LA VARIACIÓN ESTACIONAL INDICA QUE LA MAYOR ACTIVIDAD DE TORMENTAS ELÉCTRICAS SE PRODUCE EN EL VERANO, CON MENOS DE 10% EN OTOÑE E INVIERNO. SE OBTUVO UNA CORRELACIÓN SIGNIFICATIVA ENTRE LOS DATOS DE PRECIPITACIÓN DE UNA RED DE 66 ESTACIONES Y LA FRECUENCIA DE DESCARGA. SE DIO ESPECIAL ATENCIÓN A LA CUESTIÓN DE LA ACTIVIDAD ELÉCTRICA ATMOSFÉRICA Y EL CLIMA EN EL VALLE DE MÉXICO.Instituto de Ciencias de la Atmósfera y Cambio Climático, Universidad Nacional Autónoma de México2009-10-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revistascca.unam.mx/atm/index.php/atm/article/view/8525Atmósfera; Vol. 17 Núm. 2 (2004)Atmósfera; Vol. 17 No. 2 (2004)2395-88120187-6236reponame:Atmósferainstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMenghttps://www.revistascca.unam.mx/atm/index.php/atm/article/view/8525/7995info:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/85252024-08-16T16:52:34Z |

Atmospheric electric activity measurements have been recorded continuously by a punctual lightning system at a tropical highland observatory from 1988 – onwards, and were analyzed to obtain lightning statistical confident results for thunderstorms occurrence on the leeward side of the southern mountain ridge of México’s Valley. Shown, as examples, are individual profiles of the atmospheric electrical activity, associated with severe storms. The results make clear that the fastest possible sequence of electrical measurements is required to obtain significant and application oriented data in connection with a whole series of thunderstorms taking into account the mean time variation of the atmospheric electricity measurements at an altitude of 2270 m a.s.l. The seasonal variation indicates that the lightning flash peak currents were found to be larger in summer with less than 10% occurring in the autumn and winter. With rainfall data from a network of 66 stations, we obtained a significant correlation with the lightning frequency. Special attention was undertaken concerning the question of the atmospheric electrical activity and climate at the Valley of México. |
