Query: "Clusterization" and intermittency of temperature fluctuations in
  turbulent convection   Temperature time traces are obtained in turbulent thermal convection at high
Rayleigh numbers. Measurements are made in the midplane of the apparatus, near
the sidewall but outside the boundary layer. A telegraph approximation for
temperature traces is generated by setting the fluctuation amplitude to 1 or 0
depending on whether or not it exceeds the mean value. Unlike the standard
diagnostics of intermittency, the telegraph approximation allows one to
distinguish the tendency of events to cluster ("clusterization") from their
large-scale variability in amplitude. A qualitative conclusion is that
amplitude intermittency might mitigate clusterization effects.
