barotropic model

barotropic model

[‚bar·ə′träp·ik ′mäd·əl]
(meteorology)
Any of a number of model atmospheres in which some of the following conditions exist throughout the motion: coincidence of pressure and temperature surfaces, absence of vertical wind shear, absence of vertical motions, absence of horizontal velocity divergence, and conservation of the vertical component of absolute vorticity.
