Before revision:  Travelling vortex and bubble convection experiments show that the imbalance arising from assimilation of the momentum fields can be eliminated by using this blended model, thereby achieving balanced analysis fields . The leftover imbalance in the thermodynamics can be quantified by scale analysis .
