Abstract
In this work the surface temperature anomaly (dTG) and sunspot number (Rz) time series in the period 1880-2000 are studied with wavelet multi-resolution analysis. We found a very low correlation of 0.11 between dTG and Rz in the 11-yr-solar cycle band. A higher correlation of 0.66 is found in the â¼22-yr-band with zero lag correlation coefficient between dTG and Rz. Furthermore, the long-term trend is markedly different between dTG and Rz. This might occurs because of the long-term warming on the last century, which is attributed mainly to anthropogenic effects.
