Martian atmosphere breeding: elucidating atmospheric instabilities
Here, we apply the breeding method to the NASA/NOAA Mars Global Circulation Model. This technique is extended through the application of mean and perturbation energy equations, which are applied exactly to the base state and bred vector. This allows the specific diagnosis of instability types, clarifies conversions between kinetic and potential energy, and denotes favored locations for error growth, bolstering physical insight into the atmospheric dynamics of Mars. Although the current model only allows for constant dust profiles, with dust lifting parameterizations the bred vectors should provide a tool to assess the instability processes in dust storms. Breeding experiments can also assist in the optimal tuning of an ensemble data assimilation system, such as the selection of inflation and localization schemes.
