| Abstract | The role of the Suns activity on the climate changes has been revived by the concern of its uncertainty associated to questions involving the anthropogenic effects on the climate. One key element to understand the connections between Sun and climate/weather has been the search for possible influences of solar activity on the different meteorological and/or climatological parameters. In this work, monthly historical data of temperature and rainfall (1912-2008) from Santa Maria - South of Brazil (29ºS, 53ºW) have been correlated with sunspot number data. Wavelets analyses have been applied in order to find cross-correlations and coherencies in terms of direct or indirect effect of the solar activity on the rainfall and temperature. The monthly cross-wavelet shows a periodicity of 12 months (1 yr) considering the solar effect on the temperature, which was constant for all period and presented the most intensity on the solar maximums. For the rainfall series, a periodicity around 12 month (1 yr) was observed and more evident near of the solar maximum, but not constant for the analysed period, as observed for the first case. The cycles of rainfall show a periodicity of 36-60 months (3-5 yr), which matches the ENSO cycle suggesting an El Niño South Oscillation ENSOs control of rainfall in the region. Therefore, in general, for temperature and rainfall, the power spectra increase significantly with the increasing of sunspot number. The maximum spectra were observed near the solar maximum. The coherencies were higher than 0.7 indicating a high correlation between the solar activity and the studied meteorological parameters. |
