Popis: We have analyzed time series of solar wind speed, density, temperature and interplanetary magnetic field observed by ‘Advanced Composition Explorer’ (ACE) at the Earth orbits during solar maximum and minimum using nonlinear time series tools. Evidence for deterministic nonlinearity is present in all solar wind parameters. The dimension of the attractor obtained from each solar wind parameters varies from 2.5 to 4.5. Our result suggests that this variation is due to a different amount of noise in the solar wind parameters. We have also found that the dynamics of solar wind is almost identical during solar maximum and minimum at 1 AU. Our result supports the interaction of neighboring individual flow during its evolution from Sun and 1 AU.
