\u984c\u76ee: Nonlinear dynamics of fluids and plasmas: On-off intermittent
\n turbulence<\/p>\n
\u6982\u8981\uff1aThe amplitude and phase dynamics of coherent structures in
\n intermittent turbulence in fluids and plasmas is studied using
\n direct simulations of Navier-Stokes equations and
\n magnetohydrodynamics equations, as well as in-situ observations of
\n atmospheric and interplanetary turbulence. Nonlinear surrogate
\n techniques are applied to quantify the degree of phase
\n synchronization in simulated and observed data of fluid and plasma
\n turbulence. We adopt the complex Morlet wavelet to characterize
\n the amplitude dynamics by computing the Local Intermittency
\n Measure, and to characterize the phase dynamics by computing a
\n phase coherence index. Our techniques are able to detect and
\n measure coherent structures in magnetic field turbulence in
\n unshocked and shocked solar wind, as well as in atmospheric
\n turbulence above and within the Amazon forest canopy.
\n Intermittent mean-field dynamo is investigated using numerical
\n modeling of magnetohydrodynamic turbulence driven by helical
\n forcing. The importance of phase synchronization and on-off
\n intermittent turbulence in the variability of stellar magnetic
\n field and its impact on the dynamics of climate and space weather
\n of a planet and exoplanet is discussed.<\/p>\n
