A regularity criterion for a 3D tropical climate model with damping

In this paper we deal with the 3D tropical climate model with damping terms in the equation of the barotropic mode u and in the equation of the first baroclinic mode v of the velocity, and we establish a regularity criterion for this system thanks to which the local smooth solution (u, v, theta) can actually be extended globally in time.(c) 2022 Elsevier Inc.
