Possible traces of solar activity effect on the surface air temperature of Turkey
چکیده انگلیسی

In this study we investigate the effects of solar activity on the surface air temperature of Turkey. This enables us to understand existence of solar activity effects on the temperature. We used surface air temperature, pressure and tropospheric absorbing aerosol data as climate parameters and solar flare index data as solar activity indicator. We considered the parameters temperature and flare index data for the period data ranging from the beginning of January 1976 to the end of December 2006, which cover almost three solar cycles, 21st, 22nd and 23rd. However, only the period interval starting from January 1980 up to December 2005 includes the tropospheric absorbing aerosol data. We found a significant correlation between solar activity and surface air temperature for only cycle 23. We applied multitaper method to obtain the cyclic behavior of surface air temperature data sets. The most pronounced power peaks were found by this transform to be present at 1.2 and 2.5 years, which were reported earlier for some solar activity indicators. We concluded that solar activity effect exists on surface air temperature of Turkey; besides changes of greenhouse gases and tropospheric absorbing aerosols concentration have also a dominant effect on the surface air temperature of Turkey.
