What is it about?
A new surface flux scheme in atmosphere/ocean models is an important determinant of the amount of momentum, heat, and vapor exchanged between the surface and fluids, such as ground-air, ocean-air, ice-air, and ice-ocean. The conventional surface flux schemes used in finite-volume models have a negative bias. A scheme to solve this problem is proposed and evaluated the scheme in large-eddy simulation and single-column model experiments.

Why is it important?
For more accurate simulations, the individual components of the simulation model need to be as accurate as possible. In addition, the negative bias associated with conventional surface flux schemes becomes more pronounced in higher-resolution simulations. Therefore, the proposed scheme will become more important for future simulations.
Perspectives
This scheme was introduced the operational weather forecasting model in Japan Meteorological Agence.
