On the relationship between global, hemispheric and latitudinal averaged air surface temperature (GISS time series) and solar activity
The air surface temperature is a basic meteorological parameter and its variation is a primary measure of global, regional and local climate changes. In this work, the global, hemispheric and latitudinal averaged air surface temperature time series, obtained from the NASA/Goddard Institute for Space...

Zusammenfassung: | The air surface temperature is a basic meteorological parameter and its variation is a primary measure of global, regional and local climate changes. In this work, the global, hemispheric and latitudinal averaged air surface temperature time series, obtained from the NASA/Goddard Institute for Space Studies (GISS), and the Sunspot Number (
R
z
) for the interval 1880–2005, are decomposed in frequency bands through wavelet multi-resolution analysis. We have found a very low correlation between global, hemispheric and latitudinal averaged air surface temperature and
R
z
in the 11
yr solar cycle band (8–16 years) from ∼1880 to ∼1950. Afterwards the correlation is higher. A very significant correlation (
R ∼0.57 to 0.80) is found in the ∼22 yr solar Hale cycle band (16–32 years) with lags from zero to four years between latitudinal averages air surface temperature and
R
z
. Therefore it seems that the 22
yr magnetic field solar cycle might have a higher effect on Earth's climate than solar variations related to the 11
yr sunspot cycle.
► Relationship between solar activity and air surface temperature was studied. ►
R
z
and hemispheric and latitudinal air surface temperature series were used. ► The 11 and 22 year solar signals have distinct signatures for different regions. ► It was found that the 22
yr signal may have a higher influence on surface temperature. |
