text: The dissolution of minute concentration of polymers in wall-bounded flows
is well-known for its unparalleled ability to reduce turbulent friction drag.
Another phenomenon, elasto-inertial turbulence (EIT), has been far less studied
even though elastic instabilities have already been observed in dilute polymer
solutions before the discovery of polymer drag reduction. EIT is a chaotic state
driven by polymer dynamics that is observed across many orders of magnitude in
Reynolds number. It involves energy transfer from small elastic scales to large
flow scales. The investigation of the mechanisms of EIT offers the possibility
to better understand other complex phenomena such as elastic turbulence and maximum
drag reduction. In this review, we survey recent research efforts that are advancing
the understanding of the dynamics of EIT. We highlight the fundamental differences
between EIT and Newtonian/inertial turbulence from the perspective of experiments,
numerical simulations, instabilities, and coherent structures. Finally, we discuss
the possible links between EIT and elastic turbulence and polymer drag reduction,
as well as the remaining challenges in unraveling the self-sustaining mechanism
of EIT.

text: 'Since the seminal studies by Osborne Reynolds in the nineteenth century,
pipe flow has served as a primary prototype for investigating the transition to
turbulence in wall-bounded flows. Despite the apparent simplicity of this flow,
various facets of this problem have occupied researchers for more than a century.
Here we review insights from three distinct perspectives: (a) stability and susceptibility
of laminar flow, (b) phase transition and spatiotemporal dynamics, and (c) dynamical
systems analysis of the Navier—Stokes equations. We show how these perspectives
have led to a profound understanding of the onset of turbulence in pipe flow.
Outstanding open points, applications to flows of complex fluids, and similarities
with other wall-bounded flows are discussed.'

text: Idealized simulations of the tropical atmosphere have predicted that clouds
can spontaneously clump together in space, despite perfectly homogeneous settings.
This phenomenon has been called self-aggregation, and it results in a state where
a moist cloudy region with intense deep convective storms is surrounded by extremely
dry subsiding air devoid of deep clouds. We review here the main findings from
theoretical work and idealized models of this phenomenon, highlighting the physical
processes believed to play a key role in convective self-aggregation. We also
review the growing literature on the importance and implications of this phenomenon
for the tropical atmosphere, notably, for the hydrological cycle and for precipitation
extremes, in our current and in a warming climate.
