The boundary layer can be considered to possess a total momentum flux deficit, due to the frictional dissipation given by:
2.
The process is responsible for production of wind kinetic energy at a rate of 2.46 W / m 2 sustaining thus the circulation of the atmosphere against frictional dissipation.
3.
The second source is the internal sensible heat generated from frictional dissipation ( equal to W _ { out } ), which occurs near the surface within the tropical cyclone and is recycled to the system.
