Research summary

The study couples a circulation model with radiative transfer to examine how weather controls heat escaping from hot-Jupiter interiors. Spatial differences in temperature and opacity can increase overall cooling relative to uniform atmospheric models. The simulations connect this effect to circulation and drag, showing why three-dimensional atmospheric structure matters for interpreting giant-planet evolution.
