Possible direct or indirect climatic effects related to solar variability and El Niño–Southern Oscillation (ENSO) were investigated in the southern Brazil region by means of the annual mean temperatures from four weather stations 2 degrees of l

Prediction of solar activity strength for solar cycles 23 and 24 is performed on the basis of extrapolation of sunspot number spectral components. Sunspot number data during 1933-1996 periods (solar cycles 17-22) are searched for periodicities by

En el presente trabajo se hace un análisis espectral y una reconstrucción del índice geomagnético aa, usando los métodos de ondículas y de regresión iterativa (ARIST). La serie del promedio anual de aa (1868-1998) se descompuso en niveles de f

Global suface temperature has showed a rise trend in the last 150 years. This has been mainly attributed to the anthropogenic induced grenhouse gases emissions. However, the role of natural processes is not completely understood and should not be und

Physical and biological changes in the marine environment, induced by oceanic-atmospheric processes, can be imprinted in massive coral skeletons. Herein, we present an evidence of potential El Nino impacts at the Southwestern South Atlantic Ocean (SW

The aim of this work was to use an Iterative Regression Analysis Method for the determination of periodicities in geophysical time series. This method gives, for every identified sine function, its three parameters and their standard deviation due to

O aspecto mais conhecido da variabilidade solar é o ciclo de 11 anos, observado no número de manchas solares. No entanto, este ciclo tem sido observado em outros registros, como os das atividades nucleares dos cosmonuclídeos 14C e 10Be em testemun
