Sažetak
In this paper we present the relationship between the soil water deficit and the solar activity as a possible factor that influences the Earth's climate. Using the Fast Fourier Transform, a periodicity of 10.9 years was found in the data series of soil water deficit based on the Thornthwaite method of calculating evapotranspiration, which is similar to the periodicity of 10.5 years found in the series of Wolf-s relative number of sunspots. According to these results we can implicitly confirm that anomalies in the series soil water regime i.e. the occurrence of dry spells (1991-1993, 2000-2003), are closely related to an increase in solar activity.
