Abstract
Se analizaron los posibles efectos de la actividad solar en la temperatura superficial del aire y precipitación en Centro América. La correlación entre las series de manchas solares y las variables climáticas mencionadas es pobre. No obstante, se observó una tendencia creciente en los datos durante el periodo considerado. Usando el análisis de Fourier se encontraron picos de frecuencia aproximadamente a los 11 años y 5 años. Esto sugiere que la actividad solar puede ser un factor que afecta las variables climáticas.
Possible effects of solar activity on the records of air surface temperature and rainfall in Central America are analysed. The correlation between the series of sunspot numbers, surface air temperature and precipitation, is poor. However an increasing tendency in the series is observed for the time period considered. Using Fourier analysis, frequency peaks were found close to 11 years and 5 years for both solar and climate data. This suggest that solar activity might be a factor which affects the climate’s variables.
