  We present a novel physically motivated, parametrized temperature model for
phase-curve retrieval, able to self-consistently assess the variation in
thermal structure in multidimensions. To develop this approach, we drew
motivation from both full three-dimensional general circulation models and
analytic formulations, accounting for the dominant dynamical feature of tidally
locked planets, the planetary jet. Our formulation shows notable flexibility.
It can generate planetary jets of various characteristics and redistribution
efficiencies seen in the literature, including both standard eastward and
unusual westward offset hotspots, as well as more exotic configurations for
potential future observations. In our modeling scheme we utilize a tractable
set of parameters efficient enough to enable future Bayesian analysis and, in
addition to the resolved temperature structure, we return physical insights not
yet derived from retrievals: the amplitude and the phase offset, and the
location and the extent of the equatorial jet.
