摘要：
We find a class of instabilities of convective character in the so-called thermal rotating shallow water model, which is used in literature for modelling well-mixed boundary layers in the ocean and in the atmosphere. These instabilities co-exist with standard barotropic instability, having higher than this latter growth rates in a wide range of parameters, and a whole variety of unstable modes is found.
