What is a barotrope?

Answer 1

A barotrope is another name for a barotropic system - a system in meteorology in which the pressure of the atmosphere is dependent upon its density only.

Answer 2

A barotrope is a term used in fluid mechanics to describe a substance or fluid that remains at a constant density regardless of changes in pressure. In other words, the density of a barotrope does not change with pressure. This property is often used to simplify mathematical models and simulations in fluid dynamics.
