The study presents simulation results of flows in a rotating spherical layer under the influence of noise. The noise is introduced through random temporal fluctuations in the rotational speed, with a zero mean value. For the first time in numerical hydrodynamic simulations, it is demonstrated that at the stability limit, a local minimum in the generation of mean flows and a local maximum in flow velocity fluctuations occur. This aligns with theoretical predictions for dynamical systems with noise. Additionally, a new method is introduced allowing to simplify the determination of the critical Reynolds number value corresponding to the stability limit in flows with noise in nonlinear calculations.
