Several first order perturbations of moderate amplitude may easily occur together in nature in a small interval of time. Each separately leads to a family of higher order terms which may total a somewhat larger amplitude. However, all the nonlinear terms of all first order perturbations may lead for a certain phase to a very large and even a divergent result. A kind of bunching, concentration of the energy in a small phase interval, occurs. This may act as a trigger and explain sudden outbursts which occur in nature (e. g., in solar flares, CMEs, bright points, prominences, etc.), on Earth (interruption of power generators) and in the laboratory. Inducing several moderate perturbations in a quiet plasma (e.g., a Q-machine) may allow experimental verification of the theoretical convergence limit.
