Query: Temperature Structures Associated with Different Components of the
  Atmospheric Circulation on Tidally Locked Exoplanets   Observations of time-resolved thermal emission from tidally locked exoplanets
can tell us about their atmospheric temperature structure. Telescopes such as
JWST and ARIEL will improve the quality and availability of these measurements.
This motivates an improved understanding of the processes that determine
atmospheric temperature structure, particularly atmospheric circulation. The
circulation is important in determining atmospheric temperatures, not only
through its ability to transport heat, but also because any circulation pattern
needs to be balanced by horizontal pressure contrasts, therefore implying a
particular temperature structure. In this work, we show how the global
temperature field on a tidally locked planet can be decomposed into
contributions that are balanced by different components of the atmospheric
circulation. These are the superrotating jet, stationary Rossby waves, and the
divergent circulation. To achieve this, we partition the geopotential field
into components balanced by the divergent circulation and the rotational
circulation, with the latter comprising the jet and Rossby waves. The
partitioned geopotential then implies a corresponding partitioning of the
temperature via the hydrostatic relation. We apply these diagnostics to
idealised general circulation model simulations, to show how the separate
rotational and divergent circulations together make up the total
three-dimensional atmospheric temperature structure. We also show how each
component contributes distinct signatures to the thermal phase curve of a
tidally locked planet. We conclude that this decomposition is a physically
meaningful separation of the temperature field that explains its global
structure, and can be used to fit observations of thermal emission.
