- Main periodicities of the minimum extreme temperature of three stations near the Mexican Pacific coast Blanca Mendoza D. Maravilla E. Jáuregui Biología solar activity Mexican Pacific coast Minimum extreme temperature Three minimum extreme temperature series from meteorological stations located in or near the Mexican Pacificcoast, Acapulco, Comitán and Manzanillo, are spectrally analyzed. The series cover a period from 1941 to1981. The spectral analysis indicates that a significant quasiquinquenial periodicity (~5 yrs) is present in Comitán and Manzanillo, even more, Acapulco also shows a frequency ~5yr if the uncertainties are takeninto account. This spectral peak can be considered either as related to solar activity or to strong El Niñoevents. The remaining periodicities can be associated to meteorological phenomena like El Niño and thequasi-biennial oscillation or to some solar activity phenomena. Furthermore, the behavior deduced from acoherence spectra analysis between the temperature and the Southern Oscillation Index, considered as aproxy of El Niño, and sunspot number, considered as a proxy of solar activity, indicates that the stationscloser to the ocean might be more influenced by El Niño than by solar activity, while the station inland hasboth influences. 2006 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56519102 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.1 Vol.19
