Climatology of severe local thunderstorms (TLS) in the Metropolitan Area of Guadalajara [Climatología de las tormentas eléctricas locales severas (TELS) en la Zona Metropolitana de Guadalajara]

The presence of severe weather phenomena (tornados, hailstorms and linear winds with destructive gusts) is related to important changes in the morphology of the thunderstorms. The thunderstorms that reach that stage are considered as a special type of thunderstorms called local severe thunderstorms (TELS). The development of TELS in the Metropolitan Area of Guadalajara (ZMG) is a reality and should be considered in the protection of society due to the losses of lives, material damages and considerable effects that happen as a consequence of these. As we don't have a chronology of TELS in ZMG it was necessary to make a compilation of them as base to their climatology. Among the results obtained is that TELS happens from May until November, but especially in the months of June, July and August. Most happen during hours of the afternoon or of the night, but not a insignificant group also happens during the dawn. It is established that TELS constitute an important element of the climate of ZMG that cannot be ignored from the scientific point of view and much less in practice, for the effects that takes place in many of them
