Abstract Knowledge of decadal‐centennial‐scale precipitation cycles is important for
predicting the status of water resources and thus food security in the region influenced by …

The recent extended minimum of solar and geomagnetic variability (XSM) mirrors the XSMs
in the nineteenth and twentieth centuries: 1810–1830 and 1900–1910. Such extended …

The influence of solar/geomagnetic activity on climate variables still remains a fully
unclarified problem, although many scientific efforts have been made to better understand it …

We analyze 100–150 years-long temperature and precipitation records from 14
meteorological stations in Romania, in connection with long-term trends in solar and …

A similar-cycle method is introduced to predict the maximum amplitude of the geomagnetic
index aa for the 11-yr solar cycle. This method is based on the idea that similar cycles tend …

Modern-day solar cycles due to the solar magnetic field oscillation are well recognized.
Owing to the response of Earth's climate to solar activity fluctuation, solar cycles in the …

An integral response model is proposed to describe the relationship between geomagnetic
activity (aa index) and solar activity (represented by sunspot number R z): The aa at a given …

The possible changes in temperature and precipitation regime are expected to lead to
changes in the water regime of rivers. In this study, we investigate the long-term evolution of …

Using lag-correlation function analysis, the correlation coefficient at zero lag (r 0), the
maximum (rm) and the corresponding lag time (L m) between solar (R z) and geomagnetic …

The temporal evolution of the geomagnetic field is shown, on data from 24 observatories
with 100–150 years long time series of annual means, to be composed of several …
