We do not share an opinion that this 'diagnostic equation' approach to typology is completely superseded and to be discarded.
In the third section we use The AustKin database to show that the Kariera systems of Australia (in Radcliffe-Brown's sense) can be captured and mapped using diagnostic equations in grandkin terms.
The main system contrasted with Kariera was 'Aranda' that has the following diagnostic equations:
These are similar to the diagnostic equations found to define Kariera most adequately in this article.
More useful would be a method in which certain features were considered 'indicators' or 'diagnostic equations'.
It reviews the key model and diagnostic equations
, then discusses concepts based on partitioning the fields of the atmospheric state variables into a basic flow component and perturbation component, including the most often used reduced forms of the atmospheric governing equations, atmospheric wave dynamics, atmospheric instabilities, and atmospheric energetics; how the continuous governing equations can be turned into the spatially and temporally discretized equations of the numerical models; and atmospheric data assimilation.
