Before revision:  When using a spatial and vertical temporal discretisation that preserve the skew-symmetric structure of the non-canonical Hamiltonian form of the equations of motion , this scheme allows for the exact balance of all energetic exchanges in space and time.
After revision:  When using a spatial and vertical temporal discretisation that preserve the skew-symmetric structure of the non-canonical Hamiltonian form of the equations of motion . Within this context the new HEVI scheme allows for the exact balance of all energetic exchanges in space and time.
