Resumen
The analysis of surface monthly mean temperatures for stations of the Metereological Poligon of Camaguey, between 1980 and 1990, permits us to establish the decrement of the monthly mean temperature, of the order of 1° c, for may 1982 as a result of the decrease of the solar radiation produced by El Chichon stratospheric aerosols cloud that erupted between 28 march and 4 april of that year. the possible influence of clouds and precipitation is separated as a result of the analysis of sunshine and precipitation anomalies. the temporal avolution of the monthly mean temperature for the rest of 1982 was analyzed, showing a tendency to decrease in the longer term, as it has been reported by the scientific community.
