| contents | Weather signature of El Niño in western Mexico Arturo Figueroa M. Irina E. Tereshchenko Anatoliy E. Filonov César O. Monzón Ciencias de la Tierra El Niño temperature precipitation spectral analysis The study focuses on the signature of El Niño on temperature and precipitation in Guadalajara, Manzanillo, Guanajuato,Mexicali and Ensenada, Mexico. The water level of Lake Chapala reflects to some extent the integral processes in temperature andprecipitation within the Lerma-Chapala watershed. Hidden periodicities in the monthly time series included peaks of 0.5 to 22years in the normalized spectra of temperature and precipitation oscillations, with confidence limit above 90%. Within the 2-22years range, the periods of 2 to 7 years can be related to El Niño phenomenon. The periods of 9 to 22 years may be related tosolar influence. Hourly measurements of temperature, relative humidity, speed and wind direction were used to study El Niño inGuadalajara. During El Niño year, there were a large number of hours recording temperatures over 25°C. Higher than normaltemperatures were recorded from the beginning of March 1998. Low humidity values, less than 30%, were evident from lateJanuary till June of the same year. During this time, the wind showed a West-North-West steady direction, with speeds of up to 9m/s. 2003 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56842310 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.42 |
