Space-Time Multifractality Underlying Taylor's Hypothesis in Atmospheric Turbulence

Taylor's hypothesis is usually explained in terms of smaller features being advected by a large-scale transport velocity, while intrinsic temporal velocity fluctuations are slower than the corresponding inertial terms, and turbulent velocity fluctuations remain small in comparison with the transport velocity. This formulation, widely known as "frozen turbulence", is being questioned for atmospheric turbulence, and an alternative, space-time multifractally scaling hypothesis is being proposed.
