S. SALAZAR, T. G. JIMÉNEZ LIMA

Abstract

Besides their importance in meteorological and climatological processes natural and anthropogenic atmospheric aerosols, serve as adhesive surfaces on radioactive isotopes. One of these cases is the cosmogenic radionuclide 7Be. In this paper, the concentration of 7Be in surface air is presented, as it is detected at nine stations located in a tropical latitude in a coastal location on the Gulf of Mexico. 7Be concentrations and regional scale systems are found related, between the maxima and the fronts of polar air masses and between the minima with rainfall coincident with systems of tropical disturbances.
