The solar activity cycles affect all surface geosystems, including weather and climate indices, winds, rains, snow covers, mean sea level (MSL), river flowing and other hydrological cycles. The MSL and polar ice changes cause common variations of the principal moments of inertia and consequently also the Earth rotation with decadal, centennial and millennial periods. The MSL, Earth rotation and climate indices have also some oscillations with periods from several months to 10 years, whose origin is not connected with the known tidal, seasonal and other Earth effects. The shape of solar cycles is rather different from sinusoidal form, so they affect geosystems by many short-term harmonics. The solar origin of interannual oscillation of Earth rotation, MSL and climate indices is investigated by long time series of length of day, MSL variations at Stockholm, temperature and precipitation over South-Eastern Europe, El-Nino Southern Oscillation, Total Solar Irradiance, sunspot numbers and North-South solar asymmetry.
