Nonlinearities play an important role in many fields. In the field of thermonuclear fusion, it
enters into questions such as profile resilience and fluid closure. A nonlinear phenomenon that
fusion has in common with planets in astrophysics is the generation of zonal flows. In fusion,
these have an outstanding role in setting the level of turbulence and the fluid closure. The role
of resonance broadening and the effect of nonlinearities are investigated. The similarities and
differences between our systems are discussed with the population explosion and the dynamics
of nonlinear systems for drift waves by different states in the profile resilience described with
great precision. This reinforces our belief in the drift wave model’s broad application, which
encompasses current tokamaks, ITER, and the fusion pilot plant.
