Periodos característicos en las oscilaciones de parámetros meteorológicos en Cayo Arcas, México

Abstract

Data analysis of relative humidity, barometric pressure, air temperature, radiation, wind speed and wind direction from a metereological station placed at Cayo Arcas, inside of campeche bay, south of the gulf of mexico are presented. observations were made from november 3, 1990 to march 17, 1991. the spectral analysis shows the existence of events with periodicities of 12 and 24 hours for each parameter analysed, which are asociated to a local breeze system. air temperature and radiation series shows additional oscilations at 6 and 8 hours, pressure and wind series present events with additional oscilations at approximatly 4 and 16.6 days, with maximum wind speed of 21 m/s and a predominant direction from the north.
